1.3. Making UML Executable
Earlier versions of UML were not executable; they provided for an extremely limited set of actions (sending a signal, creating an object, destroying an object, as well as our personal favorite, “uninterpreted string”). In late 2001, the UML was extended by a semantics for actions. The action semantics provides a complete set of actions at a high level of abstraction. For example, actions are defined for manipulating collections of objects directly, thus avoiding the need for explicit programming of loops and iterators. Executable UML relies on these new actions to be complete.
