Send Dependency
A send dependency is a type of usage dependency that exists between an operation in a classifier and a signal. It signifies that the operation (tail end) can send the signal. (arrowhead end).
Explanation
Signals are a type of classifier and instances of them represent asynchronous messages that can be sent between two classifiers. This dependency signifies that the operation (tail end) can send the signal at the arrowhead end of the relationship. It does not specify who is the receiver of the signal but simply that the signal can be sent. An example of a single is an exception, whether in a business system or a computer system when an exception is sent (thrown) the sending instance does not wait for a return from the classifier that is expected to receive (catch) the exception.
A usage is a related element because it is the base element for the send usage which is a stereotyped usage and a type of dependency. The send stereotype adds more precision to the less specific or standard usage relationship.
