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: Class

Direct Subclasses:

Class Precedence List: Component, Class, BehavioredClassifier, EncapsulatedClassifier, StructuredClassifier, Classifier, Namespace, Type, PackageableElement, ParameterableElement, TemplateableElement, RedefinableElement, NamedElement, Element

Properties:

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 Class

Determines 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
