Interface IntAppender

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

    Modifier and Type
    Field
    Description
    static final IntAppender
    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 IntAppender
    DENSE
    An alternative IntAppender constant that appends five Base.BASE90 digits for every int input.
    static final IntAppender
    READABLE
    Appends int constants as they would be read in Java sources, in base 10, signed.

  • Field Details

    • DEFAULT

      static final IntAppender 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(int) when you want to use that as an IntAppender.

    • DENSE

      static final IntAppender DENSE
      An alternative IntAppender constant that appends five Base.BASE90 digits for every int 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 IntAppender READABLE
      Appends int constants as they would be read in Java sources, in base 10, signed.

  • Method Details

    • apply

      <S extends CharSequence & Appendable> S apply(S sb, int 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
