Class UML 2.5::Component
Description:
A Component represents a modular part of a system that encapsulates its contents and whose manifestation is replaceable within its environment.Direct Superclasses: ClassDirect Subclasses: Class Precedence List: Component, Class, BehavioredClassifier, EncapsulatedClassifier, StructuredClassifier, Classifier, Namespace, Type, PackageableElement, ParameterableElement, TemplateableElement, RedefinableElement, NamedElement, ElementProperties:
isIndirectlyInstantiated : Boolean (1 1); -- source Component packagedElement : PackageableElement (0 *); -- source Component provided : Interface (0 *); -- source Component realization : ComponentRealization (0 *); -- source Component required : Interface (0 *); -- source Component extension : Extension (0 *); -- source Class isAbstract : Boolean (1 1); -- source Class
isActive : Boolean (1 1); -- source ClassDetermines whether an object specified by this Class is active or not.
If true, then the owning Class is referred to as an active Class. If false,
then such a Class is referred to as a passive Class.Default value: FALSE

included, e.g., inherited features.{readonly}
