Execution Level

In a code debugger, we set breakpoints on lines of code. In a modeled system, we define various kinds of points in the model execution where activity might be suspended. In Executable UML, for example, we might want to stop when a state is entered or when an event is dispatched, or when any modeled action executes. Each kind of suspendable modeled activity is characterized as an Execution Unit.

Identifiers
