Class EnumLongMap

java.lang.Object
com.github.tommyettinger.ds.EnumLongMap
All Implemented Interfaces:
Iterable<EnumLongMap.Entry>
Direct Known Subclasses:
EnumLongOrderedMap
public class EnumLongMap extends Object implements Iterable<EnumLongMap.Entry>
An unordered map where the keys are Enums and values are primitive longs. Null keys are not allowed. Unlike EnumMap, this does not require a Class at construction time, which can be useful for serialization purposes. No allocation is done unless this is changing its table size and/or key universe.
This class never actually hashes keys in its primary operations (get(), put(), remove(), containsKey(), etc.), since it can rely on keys having an Enum type, and so having Enum.ordinal() available. The ordinal allows constant-time access to a guaranteed-unique int that will always be non-negative and less than the size of the key universe. The table of possible values always starts sized to fit exactly as many values as there are keys in the key universe.
The key universe is an important concept here; it is simply an array of all possible Enum values the EnumLongMap can use as keys, in the specific order they are declared. You almost always get a key universe by calling MyEnum.values(), but you can also use Class.getEnumConstants() for an Enum class. You can and generally should reuse key universes in order to avoid allocations and/or save memory; the constructor EnumLongMap(Enum[]) (with no values given) creates an empty EnumLongMap with a given key universe. If you need to use the zero-argument constructor, you can, and the key universe will be obtained from the first key placed into the EnumLongMap. You can also set the key universe with clearToUniverse(Enum[]), in the process of clearing the map.
This class tries to be as compatible as possible with EnumMap while using primitive keys, though this expands on that where possible.

  • Field Details

  • Constructor Details

    • EnumLongMap

      public EnumLongMap()
      Empty constructor; using this will postpone creating the key universe and allocating the value table until put(java.lang.Enum<?>, long) is first called (potentially indirectly). You can also use clearToUniverse(java.lang.Enum<?>[]) to set the key universe and value table.

    • EnumLongMap

      public EnumLongMap(Enum<?>[] universe)
      Initializes this map so that it has exactly enough capacity as needed to contain each Enum constant defined in universe, assuming universe stores every possible constant in one Enum type. This map will start empty. You almost always obtain universe from calling values() on an Enum type, and you can share one reference to one Enum array across many EnumLongMap instances if you don't modify the shared array. Sharing the same universe helps save some memory if you have (very) many EnumLongMap instances.
      Parameters:
      universe - almost always, the result of calling values() on an Enum type; used directly, not copied

    • EnumLongMap

      public EnumLongMap(Class<? extends Enum<?>> universeClass)
      Initializes this map so that it has exactly enough capacity as needed to contain each Enum constant defined by the Class universeClass, assuming universeClass is non-null. This simply calls EnumLongMap(Enum[]) for convenience. Note that this constructor allocates a new array of Enum constants each time it is called, where if you use EnumLongMap(Enum[]), you can reuse an unmodified array to reduce allocations.
      Parameters:
      universeClass - the Class of an Enum type that defines the universe of valid Enum items this can hold

    • EnumLongMap

      public EnumLongMap(EnumLongMap map)
      Creates a new map identical to the specified EnumLongMap. This will share a key universe with the given EnumLongMap, if non-null.
      Parameters:
      map - an EnumLongMap to copy

    • EnumLongMap

      public EnumLongMap(Enum<?>[] keys, long[] values)
      Given two side-by-side arrays, one of Enum keys, one of long values, this constructs a map and inserts each pair of key and value into it. If keys and values have different lengths, this only uses the length of the smaller array.
      Parameters:
      keys - an array of Enum keys
      values - an array of long values

    • EnumLongMap

      public EnumLongMap(Collection<? extends Enum<?>> keys, PrimitiveCollection.OfLong values)
      Given two side-by-side collections, one of Enum keys, one of long values, this constructs a map and inserts each pair of key and value into it. If keys and values have different lengths, this only uses the length of the smaller collection.
      Parameters:
      keys - a Collection of Enum keys
      values - a PrimitiveCollection of long values

  • Method Details

    • putAll

      public void putAll(Collection<? extends Enum<?>> keys, PrimitiveCollection.OfLong values)
      Given two side-by-side collections, one of Enum keys, one of long values, this inserts each pair of key and value into this map with put().
      Parameters:
      keys - a Collection of Enum keys
      values - a PrimitiveCollection of long values

    • put

      public long put(Enum<?> key, long value)
      Returns the old value associated with the specified key, or this map's defaultValue if there was no prior value. If this EnumLongMap does not yet have a key universe and/or value table, this gets the key universe from key and uses it from now on for this EnumLongMap.
      Parameters:
      key - the Enum key to try to place into this EnumLongMap
      value - the long value to associate with key
      Returns:
      the previous value associated with key, or getDefaultValue() if the given key was not present

    • putOrDefault

      public long putOrDefault(Enum<?> key, long value, long defaultValue)
      Acts like put(Enum, long), but uses the specified defaultValue instead of the default value for this EnumLongMap.
      Parameters:
      key - the Enum key to try to place into this EnumLongMap
      value - the long value to associate with key
      defaultValue - the long value to return if key was not already present
      Returns:
      the previous value associated with key, or the given defaultValue if the given key was not present

    • putAll

      public void putAll(EnumLongMap map)
      Puts every key-value pair in the given map into this, with the values from the given map overwriting the previous values if two keys are identical. If this EnumLongMap doesn't yet have a key universe, it will now share a key universe with the given map. Even if the given EnumLongMap is empty, it can still be used to obtain a key universe for this EnumLongMap (assuming it has a key universe).
      Parameters:
      map - another EnumLongMap with an equivalent key universe

    • putAll

      public void putAll(Enum<?>[] keys, long[] values)
      Given two side-by-side arrays, one of keys, one of values, this inserts each pair of key and value into this map with put(). Delegates to putAll(Enum[], int, long[], int, int).
      Parameters:
      keys - an array of keys
      values - an array of values

    • putAll

      public void putAll(Enum<?>[] keys, long[] values, int length)
      Given two side-by-side arrays, one of keys, one of values, this inserts each pair of key and value into this map with put(). Delegates to putAll(Enum[], int, long[], int, int).
      Parameters:
      keys - an array of keys
      values - an array of values
      length - how many items from keys and values to insert, at-most

    • putAll

      public void putAll(Enum<?>[] keys, int keyOffset, long[] values, int valueOffset, int length)
      Given two side-by-side arrays, one of keys, one of values, this inserts each pair of key and value into this map with put(Enum, long).
      Parameters:
      keys - an array of keys
      keyOffset - the first index in keys to insert
      values - an array of values
      valueOffset - the first index in values to insert
      length - how many items from keys and values to insert, at-most

    • get

      public long get(Object key)
      Returns the value for the specified key, or defaultValue if the key is not in the map. Note that defaultValue is often null, which is also a valid value that can be assigned to a legitimate key. Checking that the result of this method is null does not guarantee that the key is not present.
      Parameters:
      key - a non-null Object that should always be an Enum

    • getOrDefault

      public long getOrDefault(Object key, long defaultValue)
      Returns the value for the specified key, or the given default value if the key is not in the map.

    • remove

      public long remove(Object key)

    • putAll

      public void putAll(ObjectLongMap<Enum<?>> m)
      Copies all the mappings from the specified map to this map (optional operation). The effect of this call is equivalent to that of calling put(k, v) on this map once for each mapping from key k to value v in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress.
      Note that putAll(EnumLongMap) is more specific and can be more efficient by using the internal details of this class.
      Parameters:
      m - mappings to be stored in this map
      Throws:
      UnsupportedOperationException - if the putAll operation is not supported by this map
      ClassCastException - if the class of a key or value in the specified map prevents it from being stored in this map
      NullPointerException - if the specified map is null, or if this map does not permit null keys or values, and the specified map contains null keys or values
      IllegalArgumentException - if some property of a key or value in the specified map prevents it from being stored in this map

    • getAndIncrement

      public long getAndIncrement(Enum<?> key, long defaultValue, long increment)
      Returns the key's current value and increments the stored value. If the key is not in the map, defaultValue + increment is put into the map and defaultValue is returned.

    • notEmpty

      public boolean notEmpty()
      Returns true if the map has one or more items.

    • size

      public int size()
      Returns the number of key-value mappings in this map.
      Returns:
      the number of key-value mappings in this map

    • isEmpty

      public boolean isEmpty()
      Returns true if the map is empty.

    • getDefaultValue

      public long getDefaultValue()
      Gets the default value, a long which is returned by get(Object) if the key is not found. If not changed, the default value is 0.
      Returns:
      the current default value

    • setDefaultValue

      public void setDefaultValue(long defaultValue)
      Sets the default value, a long which is returned by get(Object) if the key is not found. If not changed, the default value is 0. Note that getOrDefault(Object, long) is also available, which allows specifying a "not-found" value per-call.
      Parameters:
      defaultValue - may be any long; should usually be one that doesn't occur as a typical value

    • clear

      public void clear()
      Removes all the elements from this map. The map will be empty after this call returns. This does not change the universe of possible Enum items this can hold.

    • clearToUniverse

      public void clearToUniverse(Enum<?>[] universe)
      Removes all the elements from this map and can reset the universe of possible Enum items this can hold. The map will be empty after this call returns. This changes the universe of possible Enum items this can hold to match universe. If universe is null, this resets this map to the state it would have after EnumLongMap() was called. If the table this would need is the same size as or smaller than the current table (such as if universe is the same as the universe here), this will not allocate, but will still clear any items this holds and will set the universe to the given one. Otherwise, this allocates and uses a new table of a larger size, with nothing in it, and uses the given universe. This always uses universe directly, without copying.
      This can be useful to allow an EnumLongMap that was created with EnumLongMap() to share a universe with other EnumLongMaps.
      Parameters:
      universe - the universe of possible Enum items this can hold; almost always produced by values() on an Enum

    • clearToUniverse

      public void clearToUniverse(Class<? extends Enum<?>> universe)
      Removes all the elements from this map and can reset the universe of possible Enum items this can hold. The map will be empty after this call returns. This changes the universe of possible Enum items this can hold to match the Enum constants in universe. If universe is null, this resets this map to the state it would have after EnumLongMap() was called. If the table this would need is the same size as or smaller than the current table (such as if universe is the same as the universe here), this will not allocate, but will still clear any items this holds and will set the universe to the given one. Otherwise, this allocates and uses a new table of a larger size, with nothing in it, and uses the given universe. This calls Class.getEnumConstants() if universe is non-null, which allocates a new array.
      You may want to prefer calling clearToUniverse(Enum[]) (the overload that takes an array), because it can be used to share one universe array between many EnumLongMap instances. This overload, given a Class, has to call Class.getEnumConstants() and thus allocate a new array each time this is called.
      Parameters:
      universe - the Class of an Enum type that stores the universe of possible Enum items this can hold

    • getUniverse

      public Enum<?>[] getUniverse()
      Gets the current key universe; this is a technically-mutable array, but should never be modified. To set the universe on an existing EnumLongMap (with existing contents), you can use clearToUniverse(Enum[]). If an EnumLongMap has not been initialized, just adding a key will set the key universe to match the given item.
      Returns:
      the current key universe

    • containsValue

      public boolean containsValue(long value)
      Returns true if the specified value is in the map. Note this traverses the entire map and compares every value, which may be an expensive operation.

    • containsKey

      public boolean containsKey(Object key)

    • findKey

      public Enum<?> findKey(long value)
      Returns the key for the specified value, or null if it is not in the map. Note this traverses the entire map and compares every value, which may be an expensive operation.
      Returns:
      the corresponding Enum if the value was found, or null otherwise

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public boolean equals(Object obj)
      Overrides:
      equals in class Object

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • toString

      public String toString(String entrySeparator)
      Delegates to toString(String, boolean) with the given entrySeparator and without braces. This is different from toString(), which includes braces by default.
      Parameters:
      entrySeparator - how to separate entries, such as ", "
      Returns:
      a new String representing this map

    • toString

      public String toString(String entrySeparator, boolean braces)

    • toString

      public String toString(String entrySeparator, String keyValueSeparator, boolean braces, Appender<Enum<?>> keyAppender, LongAppender valueAppender)
      Makes a String from the contents of this ObjectObjectMap, but uses the given Appender and LongAppender to convert each key and each value to a customizable representation and append them to a temporary StringBuilder. To use the default toString representation, you can use Appender::append as an appender, or to use the readable Enum Enum.name(), use Appender.ENUM_NAME_APPENDER. Use LongAppender.DEFAULT or LongAppender.READABLE for human-readable or source-code-readable results, respectively.
      Parameters:
      entrySeparator - how to separate entries, such as ", "
      keyValueSeparator - how to separate each key from its value, such as "=" or ":"
      braces - true to wrap the output in curly braces, or false to omit them
      keyAppender - a function that takes a StringBuilder and an Enum, and returns the modified StringBuilder
      valueAppender - a function that takes a StringBuilder and a long, and returns the modified StringBuilder
      Returns:
      a new String representing this map

    • appendTo

      public StringBuilder appendTo(StringBuilder sb, String entrySeparator, boolean braces)

    • appendTo

      public StringBuilder appendTo(StringBuilder sb, String entrySeparator, String keyValueSeparator, boolean braces, Appender<Enum<?>> keyAppender, LongAppender valueAppender)
      Appends to a StringBuilder from the contents of this ObjectObjectMap, but uses the given Appender and Appender to convert each key and each value to a customizable representation and append them to a StringBuilder. To use the default toString representation, you can use Appender::append as an appender, or to use the readable Enum Enum.name(), use Appender.ENUM_NAME_APPENDER. Use LongAppender.DEFAULT or LongAppender.READABLE for human-readable or source-code-readable results, respectively.
      Parameters:
      sb - a StringBuilder that this can append to
      entrySeparator - how to separate entries, such as ", "
      keyValueSeparator - how to separate each key from its value, such as "=" or ":"
      braces - true to wrap the output in curly braces, or false to omit them
      keyAppender - a function that takes a StringBuilder and an Enum, and returns the modified StringBuilder
      valueAppender - a function that takes a StringBuilder and a long, and returns the modified StringBuilder
      Returns:
      sb, with the appended keys and values of this map

    • replace

      public long replace(Enum<?> key, long value)

    • computeIfAbsent

      public long computeIfAbsent(Enum<?> key, com.github.tommyettinger.function.ObjToLongFunction<? super Enum<?>> mappingFunction)

    • remove

      public boolean remove(Object key, long value)

    • combine

      public long combine(Enum<?> key, long value, com.github.tommyettinger.function.LongLongToLongBiFunction remappingFunction)
      Just like Map's merge() default method, but this doesn't use Java 8 APIs (so it should work on RoboVM), this uses primitive values, and this won't remove entries if the remappingFunction returns null (because that isn't possible with primitive types). This uses a functional interface from Funderby.
      Parameters:
      key - key with which the resulting value is to be associated
      value - the value to be merged with the existing value associated with the key or, if no existing value is associated with the key, to be associated with the key
      remappingFunction - given a long from this and the long value, this should return what long to use
      Returns:
      the value now associated with key

    • combine

      public void combine(EnumLongMap other, com.github.tommyettinger.function.LongLongToLongBiFunction remappingFunction)
      Simply calls combine(Enum, long, LongLongToLongBiFunction) on this map using every key-value pair in other. If other isn't empty, calling this will probably modify this map, though this depends on the remappingFunction.
      Parameters:
      other - a non-null ObjectLongMap (or subclass) with a compatible key type
      remappingFunction - given a long value from this and a value from other, this should return what long to use

    • iterator

      public EnumLongMap.EntryIterator iterator()
      Reuses the iterator of the reused EnumLongMap.Entries produced by entrySet(); does not permit nested iteration. Iterate over Entries(EnumLongMap) if you need nested or multithreaded iteration. You can remove an Entry from this EnumLongMap using this Iterator.
      Specified by:
      iterator in interface Iterable<EnumLongMap.Entry>
      Returns:
      an Iterator over Map.Entry key-value pairs; remove is supported.

    • keySet

      public EnumLongMap.Keys keySet()
      Returns a Set view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.

      Note that the same Collection instance is returned each time this method is called. Use the EnumLongMap.Keys constructor for nested or multithreaded iteration.

      Returns:
      a set view of the keys contained in this map

    • values

      public EnumLongMap.Values values()
      Returns a PrimitiveCollection of the values in the map. Remove is supported. Note that the same PrimitiveCollection instance is returned each time this method is called. Use the EnumLongMap.Values constructor for nested or multithreaded iteration.
      Returns:
      a PrimitiveCollection of long values

    • entrySet

      public EnumLongMap.Entries entrySet()
      Returns a Set of Map.Entry, containing the entries in the map. Remove is supported by the Set's iterator. Note that the same iterator instance is returned each time this method is called. Use the EnumLongMap.Entries constructor for nested or multithreaded iteration.
      Returns:
      a Set of EnumLongMap.Entry key-value pairs

    • with

      public static EnumLongMap with()
      Constructs an empty map. This is usually less useful than just using the constructor, but can be handy in some code-generation scenarios when you don't know how many arguments you will have.
      Returns:
      a new map containing nothing

    • with

      public static EnumLongMap with(Enum<?> key0, Number value0)
      Constructs a single-entry map given one key and one value. This is mostly useful as an optimization for with(Enum, Number, Object...) when there's no "rest" of the keys or values. Like the more-argument with(), this will convert its Number value to a primitive long, regardless of which Number type was used.
      Parameters:
      key0 - the first and only Enum key
      value0 - the first and only value; will be converted to primitive long
      Returns:
      a new map containing just the entry mapping key0 to value0

    • with

      public static EnumLongMap with(Enum<?> key0, Number value0, Enum<?> key1, Number value1)
      Constructs a map given alternating keys and values. This is mostly useful as an optimization for with(Enum, Number, Object...) when there's no "rest" of the keys or values. Like the more-argument with(), this will convert its Number values to primitive longs, regardless of which Number type was used.
      Parameters:
      key0 - an Enum key
      value0 - a Number for a value; will be converted to primitive long
      key1 - an Enum key
      value1 - a Number for a value; will be converted to primitive long
      Returns:
      a new map containing the given key-value pairs

    • with

      public static EnumLongMap with(Enum<?> key0, Number value0, Enum<?> key1, Number value1, Enum<?> key2, Number value2)
      Constructs a map given alternating keys and values. This is mostly useful as an optimization for with(Enum, Number, Object...) when there's no "rest" of the keys or values. Like the more-argument with(), this will convert its Number values to primitive longs, regardless of which Number type was used.
      Parameters:
      key0 - an Enum key
      value0 - a Number for a value; will be converted to primitive long
      key1 - an Enum key
      value1 - a Number for a value; will be converted to primitive long
      key2 - an Enum key
      value2 - a Number for a value; will be converted to primitive long
      Returns:
      a new map containing the given key-value pairs

    • with

      public static EnumLongMap with(Enum<?> key0, Number value0, Enum<?> key1, Number value1, Enum<?> key2, Number value2, Enum<?> key3, Number value3)
      Constructs a map given alternating keys and values. This is mostly useful as an optimization for with(Enum, Number, Object...) when there's no "rest" of the keys or values. Like the more-argument with(), this will convert its Number values to primitive longs, regardless of which Number type was used.
      Parameters:
      key0 - an Enum key
      value0 - a Number for a value; will be converted to primitive long
      key1 - an Enum key
      value1 - a Number for a value; will be converted to primitive long
      key2 - an Enum key
      value2 - a Number for a value; will be converted to primitive long
      key3 - an Enum key
      value3 - a Number for a value; will be converted to primitive long
      Returns:
      a new map containing the given key-value pairs

    • with

      public static EnumLongMap with(Enum<?> key0, Number value0, Object... rest)
      Constructs a map given alternating keys and values. This can be useful in some code-generation scenarios, or when you want to make a map conveniently by-hand and have it populated at the start. You can also use EnumLongMap(Enum[], long[]), which takes all keys and then all values. This needs all keys to be Enum constants. All values must be some type of boxed Number, such as Integer or Double, and will be converted to primitive longs. Any keys that don't have Enum as their type or values that aren't Numbers have that entry skipped.
      Parameters:
      key0 - the first Enum key
      value0 - the first value; will be converted to primitive long
      rest - an array or varargs of alternating Enum, Number, Enum, Number... elements
      Returns:
      a new map containing the given keys and values

    • putPairs

      public void putPairs(Object... pairs)
      Attempts to put alternating key-value pairs into this map, drawing a key, then a value from pairs, then another key, another value, and so on until another pair cannot be drawn. All values must be some type of boxed Number, such as Integer or Double, and will be converted to primitive longs. Any keys that don't have some Enum as their type or values that aren't Numbers have that entry skipped.
      If any item in pairs cannot be cast to the Enum or Number type for its position in the arguments, that pair is ignored and neither that key nor value is put into the map. If any key is null, that pair is ignored, as well. If pairs is an Object array that is null, the entire call to putPairs() is ignored. If the length of pairs is odd, the last item (which will be unpaired) is ignored.
      Parameters:
      pairs - an array or varargs of alternating Enum, Number, Enum, Number... elements

    • putLegible

      public void putLegible(String str, PartialParser<Enum<?>> keyParser)
      Adds items to this map drawn from the result of toString(String) or appendTo(StringBuilder, String, boolean). Every key-value pair should be separated by ", ", and every key should be followed by "=" before the value (which toString() does). A PartialParser will be used to parse keys from sections of str, and values are parsed with Base.readLong(CharSequence, int, int). Usually, keyParser is produced by PartialParser.enumParser(ObjToObjFunction). Any brackets inside the given range of characters will ruin the parsing, so increase offset by 1 and reduce length by 2 if the original String had brackets added to it.
      Parameters:
      str - a String containing parseable text
      keyParser - a PartialParser that returns a Enum<?> key from a section of str, typically produced by PartialParser.enumParser(ObjToObjFunction)

    • putLegible

      public void putLegible(String str, String entrySeparator, PartialParser<Enum<?>> keyParser)
      Adds items to this map drawn from the result of toString(String) or appendTo(StringBuilder, String, boolean). Every key-value pair should be separated by entrySeparator, and every key should be followed by "=" before the value (which toString(String) does). A PartialParser will be used to parse keys from sections of str, and values are parsed with Base.readLong(CharSequence, int, int). Usually, keyParser is produced by PartialParser.enumParser(ObjToObjFunction). Any brackets inside the given range of characters will ruin the parsing, so increase offset by 1 and reduce length by 2 if the original String had brackets added to it.
      Parameters:
      str - a String containing parseable text
      entrySeparator - the String separating every key-value pair
      keyParser - a PartialParser that returns a Enum<?> key from a section of str, typically produced by PartialParser.enumParser(ObjToObjFunction)

    • withPrimitive

      public static EnumLongMap withPrimitive()
      Constructs an empty map. This is usually less useful than just using the constructor, but can be handy in some code-generation scenarios when you don't know how many arguments you will have.
      Returns:
      a new map containing nothing

    • withPrimitive

      public static EnumLongMap withPrimitive(Enum<?> key0, long value0)
      Constructs a single-entry map given one key and one value. This is mostly useful as an optimization for with(Enum, Number, Object...) when there's no "rest" of the keys or values. Unlike with(), this takes unboxed long as its value type, and will not box it.
      Parameters:
      key0 - an Enum for a key
      value0 - a long for a value
      Returns:
      a new map containing just the entry mapping key0 to value0

    • withPrimitive

      public static EnumLongMap withPrimitive(Enum<?> key0, long value0, Enum<?> key1, long value1)
      Constructs a map given alternating keys and values. This is mostly useful as an optimization for with(Enum, Number, Object...) when there's no "rest" of the keys or values. Unlike with(), this takes unboxed long as its value type, and will not box it.
      Parameters:
      key0 - an Enum key
      value0 - a long for a value
      key1 - an Enum key
      value1 - a long for a value
      Returns:
      a new map containing the given key-value pairs

    • withPrimitive

      public static EnumLongMap withPrimitive(Enum<?> key0, long value0, Enum<?> key1, long value1, Enum<?> key2, long value2)
      Constructs a map given alternating keys and values. This is mostly useful as an optimization for with(Enum, Number, Object...) when there's no "rest" of the keys or values. Unlike with(), this takes unboxed long as its value type, and will not box it.
      Parameters:
      key0 - an Enum key
      value0 - a long for a value
      key1 - an Enum key
      value1 - a long for a value
      key2 - an Enum key
      value2 - a long for a value
      Returns:
      a new map containing the given key-value pairs

    • withPrimitive

      public static EnumLongMap withPrimitive(Enum<?> key0, long value0, Enum<?> key1, long value1, Enum<?> key2, long value2, Enum<?> key3, long value3)
      Constructs a map given alternating keys and values. This is mostly useful as an optimization for with(Enum, Number, Object...) when there's no "rest" of the keys or values. Unlike with(), this takes unboxed long as its value type, and will not box it.
      Parameters:
      key0 - an Enum key
      value0 - a long for a value
      key1 - an Enum key
      value1 - a long for a value
      key2 - an Enum key

    • of

      public static EnumLongMap of()
      Constructs an empty map. This is usually less useful than just using the constructor, but can be handy in some code-generation scenarios when you don't know how many arguments you will have. This is an alias for with().
      Returns:
      a new map containing nothing

    • of

      public static EnumLongMap of(Enum<?> key0, Number value0, Object... rest)
      Constructs a map given alternating keys and values. This can be useful in some code-generation scenarios, or when you want to make a map conveniently by-hand and have it populated at the start. You can also use EnumLongMap(Enum[], long[]), which takes all keys and then all values. This needs all keys to be Enum constants. All values must be some type of boxed Number, such as Integer or Double, and will be converted to primitive longs. Any keys that don't have Enum as their type or values that aren't Numbers have that entry skipped. This is an alias for with(Enum, Number, Object...).
      Parameters:
      key0 - the first Enum key
      value0 - the first value; will be converted to primitive long
      rest - an array or varargs of alternating Enum, Number, Enum, Number... elements
      Returns:
      a new map containing the given keys and values
