Class UML 2.5::MessageOccurrenceSpecification
Description:
A MessageOccurrenceSpecification specifies the occurrence of Message events,
such as sending and receiving of Signals or invoking or receiving of Operation
calls. A MessageOccurrenceSpecification is a kind of MessageEnd. Messages
are generated either by synchronous Operation calls or asynchronous Signal
sends. They are received by the execution of corresponding AcceptEventActions.
