In this example, an activity
is executed each time a branch that executed in a multi-choice construct
is complete. This example is implemented using events and subprocesses:
Each branch that executes in the multi-choice construct
ends with the throw of an asynchronous event type. If the multi-choice
construct used gateways, each branch in the gateways throw the event.
If the multi-choice construct used events, the final step in each
subprocess is a throw of the event.
A subprocess that includes the activity to execute receives
the event as a start point.
The following illustration shows
two branches from a multi-choice construct that throws the asynchronous
event type and the subprocess that uses the event type as a start
point. The branches are represented as an activity element. The
branches are inside either a gateway or a subprocess, depending on
the type of implementation used for the multi-choice construct that precedes
the multi-merge construct.
