Reception
A Reception is a feature of a Classifier, and is derived from a Signal element; it models receipt of the Signal. Receptions are treated in the same way as Operations and, where element compartments are displayed, are shown within their own compartment.
A Reception cannot be created without a Signal element, which either already exists or is created as a step in creating the Reception. The name of the Reception is drawn from the name of the Signal element, and the attributes of the Signal define the parameters of the Reception. Any changes to the Signal are reflected in the Reception, and vice versa.

OMG Specification
(UML Superstructure Specification, v2.1.1, p.447 - 448):
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. ... Receptions are shown using the same notation as for operations with the keyword <signal>.
