Class UML 2.3::Signal
Description:
A signal is a specification of send request instances communicated between objects. The receiving object handles the received request instances as specified by its receptions. The data carried by a send request (which was passed to it by the send invocation occurrence that caused that request) are represented as attributes of the signal. A signal is defined independently of the classifiers handling the signal occurrence.Direct Superclasses: ClassifierDirect Subclasses: Class Precedence List: Signal, Classifier, TemplateableElement, Type, PackageableElement, ParameterableElement, Namespace, RedefinableElement, NamedElement, ElementProperties:

If the value is true, then it is not possible to further redefine the RedefinableElement.
Note that this property is preserved through package merge operations;
that is, the capability to redefine a RedefinableElement (i.e., isLeaf=false)
must be preserved in the resulting RedefinableElement of a package merge
operation where a RedefinableElement with isLeaf=false is merged with a
matching RedefinableElement with isLeaf=true: the resulting RedefinableElement
will have isLeaf=false. Default value is false.Default value: FALSE
