Interface FloatAppender

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

  • Field Summary

    Fields
    Modifier and Type
    Field
    Description
    static final FloatAppender
    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 FloatAppender
    DENSE
    An alternative FloatAppender constant that appends five Base.BASE90 digits for every float input.
    static final FloatAppender
    READABLE
    Appends float constants as they would be read in Java sources, in base 10 with a trailing 'f'.

    Appends item to sb and returns sb for chaining.

  • Field Details

    • DEFAULT

      static final FloatAppender 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(float) when you want to use that as an FloatAppender. This actually calls Base.appendSigned(CharSequence, float) on Base.BASE10, and works with more than StringBuilder.

    • DENSE

      static final FloatAppender DENSE
      An alternative FloatAppender constant that appends five Base.BASE90 digits for every float 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 FloatAppender READABLE
      Appends float constants as they would be read in Java sources, in base 10 with a trailing 'f'.

  • Method Details

    • apply

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

    • appendDense

      static <S extends CharSequence & Appendable> S appendDense(S sb, float item)
