All Implemented Interfaces:

EnhancedCollection<I>, Iterable<I>, Collection<I>, Set<I>

public class FilteredIterableSet<T,I extends Iterable<T>>
extends ObjectSet<I>

A customizable variant on ObjectSet that uses Iterable items made of T sub-items, and only considers a sub-item (for equality and hashing purposes) if that sub-item satisfies a predicate. This can also edit the sub-items that pass the filter, such as by normalizing their data during comparisons (and hashing). You will usually want to call setFilter(ObjPredicate) and/or setEditor(ObjToSameFunction) to change the behavior of hashing and equality before you enter any items, unless you have specified the filter and/or editor you want in the constructor. Calling setModifiers(ObjPredicate, ObjToSameFunction) is recommended if you need to set both the filter and the editor; you could also set them in the constructor.
This class is related to FilteredStringSet, which can be seen as using a String as an item and the characters of that String as its sub-items. That means this is also similar to CaseInsensitiveSet, which is essentially a specialized version of FilteredIterableSet (which can be useful for serialization).

Method Details

getFilter

public com.github.tommyettinger.function.ObjPredicate<T> getFilter()

setFilter

public FilteredIterableSet<T,I> setFilter(com.github.tommyettinger.function.ObjPredicate<T> filter)

Sets the filter that determines which sub-items in an Iterable are considered for equality and hashing, then returns this object, for chaining. ObjPredicate filters could be lambdas or method references that take a sub-item and return true if that sub-item will be used for hashing/equality, or return false to ignore it. The default filter always returns true. If the filter changes, that invalidates anything previously entered into this, so before changing the filter this clears the entire data structure, removing all existing items.

Parameters:

filter - a ObjPredicate that should return true iff a sub-item should be considered for equality/hashing

Returns:

this, for chaining

getEditor

public com.github.tommyettinger.function.ObjToSameFunction<T> getEditor()

setEditor

public FilteredIterableSet<T,I> setEditor(com.github.tommyettinger.function.ObjToSameFunction<T> editor)

Sets the editor that can alter the sub-items in an Iterable item when they are being used for equality and hashing. This does not apply any changes to the items in this data structure; it only affects how they are hashed or compared. An editor could be a lambda or method reference; the only real requirement is that it takes a T sub-item and returns a T sub-item. The default filter returns the sub-item it is passed without changes. If the editor changes, that invalidates anything previously entered into this, so before changing the editor this clears the entire data structure, removing all existing items.

Parameters:

editor - a ObjToSameFunction that will be given a sub-item and may return a potentially different T sub-item

Returns:

this, for chaining

setModifiers

public FilteredIterableSet<T,I> setModifiers(com.github.tommyettinger.function.ObjPredicate<T> filter,
 com.github.tommyettinger.function.ObjToSameFunction<T> editor)

Equivalent to calling mySet.setFilter(filter).setEditor(editor), but only clears the data structure once.

Parameters:

filter - a ObjPredicate that should return true iff a sub-item should be considered for equality/hashing

editor - a ObjToSameFunction that will be given a sub-item and may return a potentially different T sub-item

Returns:

this, for chaining

• setFilter(ObjPredicate)
• setEditor(ObjToSameFunction)

hashHelper

protected int hashHelper(I s)

place

protected int place(Object item)

Description copied from class: ObjectSet

Returns an index >= 0 and <= ObjectSet.mask for the specified item, mixed.

Overrides:

place in class ObjectSet<I extends Iterable<T>>

Parameters:

item - a non-null Object; its hashCode() method should be used by most implementations

Returns:

an index between 0 and ObjectSet.mask (both inclusive)

equate

public boolean equate(Object left,
 Object right)

Compares two objects for equality by the rules this filtered data structure uses for keys. This will return true if the arguments are reference-equivalent or both null. Otherwise, it requires that both are Iterables and compares them using the filter and editor of this object.

Overrides:

equate in class ObjectSet<I extends Iterable<T>>

Parameters:

left - must be non-null; typically a key being compared, but not necessarily

right - may be null; typically a key being compared, but can often be null for an empty key slot, or some other type

Returns:

true if left and right are equivalent according to the rules this filtered type uses

hashCode

public int hashCode()

Specified by:

hashCode in interface Collection<T>

Specified by:

hashCode in interface Set<T>

Overrides:

hashCode in class ObjectSet<I extends Iterable<T>>

I - the type of items, which must be either Iterable or an implementing class, containing T sub-items

Parameters:

filter - a ObjPredicate<T> that should return true iff a sub-item should be considered for equality/hashing

editor - a ObjToSameFunction<T> that will be given a sub-item and may return a potentially different T sub-item

items - an array or varargs of I that will be used in the new set

Returns:

a new FilteredIterableSet containing the entirety of items, as the filter and editor permit

parse

public static <T,
I extends Iterable<T>>
FilteredIterableSet<T,I> parse(com.github.tommyettinger.function.ObjPredicate<T> filter,
 com.github.tommyettinger.function.ObjToSameFunction<T> editor,
 String str,
 String delimiter,
 PartialParser<I> parser)

Calls parse(ObjPredicate, ObjToSameFunction, String, String, PartialParser, boolean) with brackets set to false.

Type Parameters:

T - the type of item in each Iterable

I - the Iterable of T type this holds

Parameters:

filter - a ObjPredicate<T> that should return true iff a sub-item should be considered for equality/hashing

editor - a ObjToSameFunction<T> that will be given a sub-item and may return a potentially different T sub-item

str - a String that will be parsed in full

delimiter - the delimiter between items in str

parser - a PartialParser that returns an I item from a section of str

Returns:

a new collection parsed from str

parse

public static <T,
I extends Iterable<T>>
FilteredIterableSet<T,I> parse(com.github.tommyettinger.function.ObjPredicate<T> filter,
 com.github.tommyettinger.function.ObjToSameFunction<T> editor,
 String str,
 String delimiter,
 PartialParser<I> parser,
 boolean brackets)

Creates a new HolderSet using extractor and fills it by calling EnhancedCollection.addLegible(String, String, PartialParser, int, int) on either all of str (if brackets is false) or str without its first and last chars (if brackets is true). Each item is expected to be separated by delimiter.

Type Parameters:

T - the type of item in each Iterable

I - the Iterable of T type this holds

Parameters:

filter - a ObjPredicate<T> that should return true iff a sub-item should be considered for equality/hashing

editor - a ObjToSameFunction<T> that will be given a sub-item and may return a potentially different T sub-item

str - a String that will be parsed in full (depending on brackets)

delimiter - the delimiter between items in str

parser - a PartialParser that returns an I item from a section of str

brackets - if true, the first and last chars in str will be ignored

Returns:

a new collection parsed from str

parse

public static <T,
I extends Iterable<T>>
FilteredIterableSet<T,I> parse(com.github.tommyettinger.function.ObjPredicate<T> filter,
 com.github.tommyettinger.function.ObjToSameFunction<T> editor,
 String str,
 String delimiter,
 PartialParser<I> parser,
 int offset,
 int length)

Creates a new HolderSet using extractor and fills it by calling EnhancedCollection.addLegible(String, String, PartialParser, int, int) with the other five parameters as-is.

Type Parameters:

T - the type of item in each Iterable

I - the Iterable of T type this holds

Parameters:

filter - a ObjPredicate<T> that should return true iff a sub-item should be considered for equality/hashing

editor - a ObjToSameFunction<T> that will be given a sub-item and may return a potentially different T sub-item

str - a String that will have the given section parsed

delimiter - the delimiter between items in str

parser - a PartialParser that returns an I item from a section of str

offset - the first position to parse in str, inclusive

length - how many chars to parse, starting from offset

Returns:

a new collection parsed from str
