  - ### accept

    public void accept(Visitor v)
    Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, i.e., the most specific visitXXX() call comes last.
    Specified by:
      `accept` in class `Instruction`
    Parameters:
      `v` - Visitor object

  - ### dump

    public void dump(DataOutputStream out) throws IOException
    Dump instruction as byte code to stream out.
    Overrides:
      `dump` in class `CPInstruction`
    Parameters:
      `out` - Output stream
    Throws:
      `IOException` - Thrown when an I/O exception of some sort has occurred.

  - ### getExceptions

    public Class<?>[] getExceptions()
