Full quote If the Transition terminates on the edge of the composite State (i.e., without entering the State), then all the Regions are entered using the default entry rule above. Next snippet If the Transition explicitly enters one or more Regions (in case of a fork), these Regions are entered explicitly and the others by default. Related snippets A Transition represents an arc between exactly one source Vertex and exactly one Target vertex (the source and targets may be the same Vertex). It may form part of a compound transition, which takes the StateMachine from one steady State configuration... If the composite State is also an orthogonal State with multiple Regions, each of its Regions is also entered, either by default or explicitly. Related snippets (backlinks) If the Transition explicitly enters one or more Regions (in case of a fork), these Regions are entered explicitly and the others by default. Regardless of how a State is entered, the StateMachine is deemed to be “in” that State even before any entry Behavior or effect Behavior (if defined) of that State start executing. Exit points are the inverse of entry points. That is, Transitions originating from a Vertex within the composite State can terminate on the exit point. In a well-formed model, such a Transition should have a corresponding external Transition outgoing from the same exit point, representing a continuation of the terminating Transition. If the composite State has an exit Behavior defined, it is executed after any effect Behavior of the incoming inside Transition and before any effect Behavior of the outgoing external Transition. Entry points represent termination points (sources) for incoming Transitions and origination points (targets) for Transitions that terminate on some internal Vertex of the composite State. In effect, the latter is a continuation of the external incoming Transition, with the proviso that the execution of the entry Behavior of the composite State (if defined) occurs between the effect Behavior of the incoming Transition and the effect ... If there is no outgoing Transition inside the composite State, then the incoming Transition simply performs a default State entry. Visit also Visit also (backlinks) Flags
