    • getOpcode

      public int getOpcode()
      Returns the opcode of this instruction.
      返回:
      the opcode of this instruction.

    • getType

      public abstract int getType()
      Returns the type of this instruction.
      返回:
      the type of this instruction, i.e. one the constants defined in this class.

    • getPrevious

      public AbstractInsnNode getPrevious()
      Returns the previous instruction in the list to which this instruction belongs, if any.
      返回:
      the previous instruction in the list to which this instruction belongs, if any. May be null.

    • getNext

      public AbstractInsnNode getNext()
      Returns the next instruction in the list to which this instruction belongs, if any.
      返回:
      the next instruction in the list to which this instruction belongs, if any. May be null.

    • accept

      public abstract void accept(MethodVisitor cv)
      Makes the given code visitor visit this instruction.
      参数:
      cv - a code visitor.

    • acceptAnnotations

      protected final void acceptAnnotations(MethodVisitor mv)
      Makes the given visitor visit the annotations of this instruction.
      参数:
      mv - a method visitor.

    • clone

      public abstract AbstractInsnNode clone(Map<LabelNode,LabelNode> labels)
      Returns a copy of this instruction.
      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.

    • cloneAnnotations

      protected final AbstractInsnNode cloneAnnotations(AbstractInsnNode insn)
      Clones the annotations of the given instruction into this instruction.
      参数:
      insn - the srccode instruction.
      返回:
      this instruction.
