Class Goto

java.lang.Object
  jef.dna.instructions.impl.InstructionAncestor
      jef.dna.instructions.impl.Goto

All Implemented Interfaces:

java.lang.Cloneable, Instruction, BytesCountable

public class Goto
extends InstructionAncestor

This class maps the GOTO bytecode instruction which branches always. Execution proceeds at that offset from the address of the opcode of this goto instruction. The target address must be that of an opcode of an instruction within the method that contains this goto instruction.
