  • Method Details

    • getType

      public int getType()
      Description copied from class: AbstractInsnNode
      Returns the type of this instruction.
      Specified by:
      getType in class AbstractInsnNode
      Returns:
      the type of this instruction, i.e. one the constants defined in this class.
    • accept

      public void accept(MethodVisitor methodVisitor)
      Description copied from class: AbstractInsnNode
      Makes the given method visitor visit this instruction.
      Specified by:
      accept in class AbstractInsnNode
      Parameters:
      methodVisitor - a method visitor.
    • clone

      public AbstractInsnNode clone(Map<LabelNode,LabelNode> clonedLabels)
      Description copied from class: AbstractInsnNode
      Returns a copy of this instruction.
      Specified by:
      clone in class AbstractInsnNode
      Parameters:
      clonedLabels - a map from LabelNodes to cloned LabelNodes.
      Returns:
      a copy of this instruction. The returned instruction does not belong to any InsnList.
