    • JumpInsnNode

      public JumpInsnNode(int opcode, LabelNode label)
      Constructs a new JumpInsnNode.
      参数:
      opcode - the opcode of the type instruction to be constructed. This opcode must be IFEQ, IFNE, IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPLT, IF_ICMPGE, IF_ICMPGT, IF_ICMPLE, IF_ACMPEQ, IF_ACMPNE, GOTO, JSR, IFNULL or IFNONNULL.
      label - the operand of the instruction to be constructed. This operand is a label that designates the instruction to which the jump instruction may jump.

    • setOpcode

      public void setOpcode(int opcode)
      Sets the opcode of this instruction.
      参数:
      opcode - the new instruction opcode. This opcode must be IFEQ, IFNE, IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPLT, IF_ICMPGE, IF_ICMPGT, IF_ICMPLE, IF_ACMPEQ, IF_ACMPNE, GOTO, JSR, IFNULL or IFNONNULL.

    • getType

      public int getType()

      Returns the type of this instruction.
      指定者:
      getType 在类中 AbstractInsnNode
      返回:
      the type of this instruction, i.e. one the constants defined in this class.

    • accept

      public void accept(MethodVisitor mv)
      从类复制的说明: AbstractInsnNode
      Makes the given code visitor visit this instruction.
      指定者:
      accept 在类中 AbstractInsnNode
      参数:
      mv - a code visitor.

    • clone

      public AbstractInsnNode clone(Map<LabelNode,LabelNode> labels)
      从类复制的说明: AbstractInsnNode
      Returns a copy of this instruction.
      指定者:
      clone 在类中 AbstractInsnNode
      参数:
      labels - a map from LabelNodes to cloned LabelNodes.
      返回:
      a copy of this instruction. The returned instruction does not belong to any InsnList.
