Interface LongAppender

public interface LongAppender
A functional interface that takes and returns an object that is a CharSequence and is Appendable, appending a long item to it. This is often a method reference to a method in Base, such as Base.appendSigned(CharSequence, long).

    Fields
    Modifier and Type
    Field
    Description
    static final LongAppender
    DEFAULT
    A static constant to avoid Android and its R8 compiler allocating a new lambda every time StringBuilder::append is present at a call-site.
    static final LongAppender
    DENSE
    An alternative LongAppender constant that appends five Base.BASE90 digits for every long input.
    static final LongAppender
    READABLE
    Appends long constants as they would be read in Java sources, in base 10 with a trailing 'L'.

    <S extends CharSequence & Appendable>
    S
    apply(S sb, long item)
    Appends item to sb and returns sb for chaining.

  • Field Details

    • DEFAULT

      static final LongAppender DEFAULT
      A static constant to avoid Android and its R8 compiler allocating a new lambda every time StringBuilder::append is present at a call-site. This should be used in place of StringBuilder.append(long) when you want to use that as an LongAppender. This actually calls Base.appendSigned(CharSequence, long) on Base.BASE10, and works with more than StringBuilder.

    • DENSE

      static final LongAppender DENSE
      An alternative LongAppender constant that appends five Base.BASE90 digits for every long input. The five ASCII chars are not expected to be human-readable.
      This is a static constant to avoid Android and its R8 compiler allocating a new lambda every time this lambda would be present at a call-site.

    • READABLE

      static final LongAppender READABLE
      Appends long constants as they would be read in Java sources, in base 10 with a trailing 'L'.

  • Method Details

    • apply

      <S extends CharSequence & Appendable> S apply(S sb, long item)
      Appends item to sb and returns sb for chaining.
      Type Parameters:
      S - any type that is both a CharSequence and an Appendable, such as StringBuilder, StringBuffer, CharBuffer, or CharList
      Parameters:
      sb - an Appendable CharSequence that will be modified, such as a StringBuilder
      item - the item to append
      Returns:
      first, after modification
