031
032/**
033 An action implementing this interface is a choice action. When an FSMActor
034 is fired, an enabled transition among the outgoing transitions of the
035 current state is chosen. The choice actions contained by the chosen
036 transition are executed. A choice action may be executed more than once
037 during an iteration in domains with fixed-point semantics.
