  • Field Details

    • numEntries

      protected int numEntries
      number of entries in expanded array
    • translate

      protected int translate
      translate all values by this amount
  • Constructor Details

    • CountEmitter

      protected CountEmitter(String name)
      Create a count/value emitter for a specific field with values in the range of [0..0xFFFF].
      Parameters:
      name - name of the generated array
    • CountEmitter

      protected CountEmitter(String name, int translate)
      Create a count/value emitter for a specific field with translated values in the range of [0..0xFFFF].
      Parameters:
      name - name of the generated array
      translate - translate all values by this amount, e.g provide +1 to allow values in [-1, 0xFFFE]
  • Method Details

    • emitUnpack

      public void emitUnpack()
      Emits count/value unpacking code for the generated array.
      Specified by:
      emitUnpack in class PackEmitter
      See Also:
    • emitUnpackChunk

      protected void emitUnpackChunk()
      Emits count/value unpacking code for one chunk of the generated array. Base class assumes values are in [0, 0xFFFF]. Subclasses may override.
      See Also:
    • emit

      public void emit(int count, int value)
      Emit one count/value pair.

      Automatically translates value by the translate value.

      Parameters:
      count - a int.
      value - a int.
    • emitValue

      protected void emitValue(int value)
      Emit one value. Base class assumes range [0, 0xFFFF], subclasses may override.
      Parameters:
      value - integer value to emit, assumed to be in the range [0, 0xFFFF]
    • emitCountValueString

      public void emitCountValueString(int[] a)
      Emits a plain int array as a count/value string. Expects the preamble code (declaration, javadoc) to already be emitted. Values in the array must be no larger than 0xFFFF (encoded as char), array must have at least one element.
    • emitter

      public static CountEmitter emitter(int states, int translation, String name)
