      • getPaddedSize

         Integer getPaddedSize(Integer offset)

        Get the padded size in bytes of this instruction.

        Parameters:
        offset - the offset at which this instruction is found.

      • read

         Unit read(ByteCodeInput input)

        Read this instruction from the given ByteCodeInput. Expects ByteCodeInput to be in JVM class file format and just before a instruction of this kind.

        Parameters:
        input - the ByteCodeInput from which to read

      • write

         Unit write(ByteCodeOutput output)

        Write this instruction to the given ByteCodeOutput.

        Parameters:
        output - the ByteCodeOutput to which to write
