Examples of org.osoa.sca.ComponentContext

org.osoa.sca.ComponentContext
Interface providing programmatic access to a component's SCA context as an alternative to injection. It provides access to reference and property values for the component and provides a mechanism for obtaining a reference to a service that can be passed to other components.
SCA components obtain an instance of this interface through injection. Non-SCA client code may also obtain an instance through runtime-specific mechanisms. @version $Rev: 512440 $ $Date: 2007-02-27 22:08:01 +0000 (Tue, 27 Feb 2007) $
