Description
A reception is a declaration stating that a classifier is prepared to react to the receipt of a signal. A reception designates
a signal and specifies the expected behavioral response. The details of handling a signal are specified by the behavior associated
with the reception or the classifier itself.

Associations
• signal: Signal [0..1] The signal that this reception handles.
Constraints

Semantics
The receipt of a signal instance by the instance of the classifier owning a matching reception will cause the asynchronous
invocation of the behavior specified as the method of the reception. A reception matches a signal if the received signal is
a subtype of the signal referenced by the reception. The details of how the behavior responds to the received signal depends
on the kind of behavior associated with the reception. (For example, if the reception is implemented by a state machine, the
signal event will trigger a transition and subsequent effects as specified by that state machine.)
Reception s specify triggered effects (see BehavioredClassifier on page 451).
Notation
Reception s are shown using the same notation as for operations with the keyword «signal», as shown
in Figure 13.16.
