- - ### Constructor Detail

    - #### INVOKEVIRTUAL

          public INVOKEVIRTUAL(int index)

  - ### Method Detail

    - #### 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`

    - #### getExceptions

          public Class<?>[] getExceptions()
