It is a CompositeActivity that is used to handle an event; typically it can be raised from the host or by the run time in reponse to a delay timer expiring. EventDrivenActivity is inherited from SequenceActivity; therefore it is a sequence that has the additional restriction that the first activity should be an IEventActivity.
The first child of an EventDrivenActivity activity must be an activity that inherits from IEventActivity. All subsequent children can be activities of any type. The IEventActivity blocks and waits for the pending occurrence of some events, such as starting a timer or the arrival of a message. When the event occurs, the IEventActivity finishes running, and then all subsequent activities are executed.
For example, an activity that supports event handling can be used inside the EventDrivenActivity but the activity cannot have event handlers attached to itself.
Derivative of Activity that is the base class for all activities that contain other activities. A Composite Activity is responsible for managing the execution of its child activities.
