20  * Wrapper class for `compound' operations, virtual instructions that
21  * don't exist as byte code, but give a useful meaning. For example,
22  * the (virtual) PUSH instruction takes an arbitray argument and produces the
23  * appropiate code at dump time (ICONST, LDC, BIPUSH, ...). Also you can use the
24  * SWITCH instruction as a useful template for either LOOKUPSWITCH or
25  * TABLESWITCH.
26  *
27  * The interface provides the possibilty for the user to write
28  * `templates' or `macros' for such reuseable code patterns.
