57 /**
58  * Wrapper class for `compound' operations, virtual instructions that
59  * don't exist as byte code, but give a useful meaning. For example,
60  * the (virtual) PUSH instruction takes an arbitray argument and produces the
61  * appropiate code at dump time (ICONST, LDC, BIPUSH, ...). Also you can use the
62  * SWITCH instruction as a useful template for either LOOKUPSWITCH or
63  * TABLESWITCH.
64  *
65  * The interface provides the possibilty for the user to write
66  * `templates' or `macros' for such reuseable code patterns.
