Stateflow

Transition Flow Graph Types

Before transitions are executed for an active state or for a chart, they are grouped by the following types:

• Default flow graphs are all default transition segments that start with the same parent.
• Inner flow graphs are all transition segments that originate on a state and reside entirely within that state.
• Outer flow graphs are all transition segments that originate on the respective state but reside at least partially outside that state.

Each set of flow graphs includes other transition segments connected to a qualifying transition segment through junctions and transitions. Consider the following example:

In this example, state A has both an inner and a default transition that connect to a junction with outgoing transitions to states A.A1 and A.A2. If state A is active, its set of inner flow graphs includes the inner transition and the outgoing transitions from the junction to state A.A1 and A.A2. In addition, state A's set of default flow graphs includes the default transition to the junction along with the two outgoing transitions from the junction to state A.A1 and A.A2. In this case, the two outgoing transition segments from the junction become members of more than one flow graph type.
