All Implemented Interfaces:

java.lang.Cloneable, Instruction, BytesCountable

public class IInc
extends InstructionAncestor

This class maps the IINC bytecode instruction which increments the int referenced by the first IINC parameter (this is an index into the local variable array of the current frame) by a constant given as second paramenter of the bytecode instruction.
