UML Standard Profile
stereotype call
Call is a stereotyped usage dependency whose source is an operation and whose target is an operation. The relationship may also be subsumed to the class containing an operation, with the meaning that there exists an operation in the class to which the dependency applies. A call dependency specifies that the source operation or an operation in the source class invokes the target operation or an operation in the target class. A call dependency may connect a source operation to any target operation that is within scope including, but not limited to, operations of the enclosing classifier and operations of other visible classifiers.
