    - #### INSTANCEOF

          public INSTANCEOF(int index)

  - ### Method Detail

    - #### getExceptions

          public Class<?>[] getExceptions()

      Specified by:
        `getExceptions` in interface `ExceptionThrower`

    - #### getLoadClassType

          public ObjectType getLoadClassType(ConstantPoolGen cpg)

      Description copied from interface: `LoadClass`
      Returns the ObjectType of the referenced class or interface that may be loaded and resolved.
      Specified by:
        `getLoadClassType` in interface `LoadClass`
      Returns:
        object type that may be loaded or null if a primitive is referenced

    - #### 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
