org.apache.tuscany.spi.component.CompositeComponent
The runtime instantiation of an SCA composite component. Composites may contain child components, offer services, and have references. Children are contained in two namespaces, an application namespace for end-user components deployed to a runtime, and a system namespace for components that provide system services. @version $Rev: 451895 $ $Date: 2006-10-01 23:58:18 -0700 (Sun, 01 Oct 2006) $
