      jef.dna.instructions.impl.IXOr

All Implemented Interfaces:

java.lang.Cloneable, Instruction, BytesCountable

public class IXOr
extends InstructionAncestor

This class maps the IXOR bytecode instruction which performs the boolean xor over the first two values popped from the operand stack. The result is then pushed onto the operand stack.
