Examples of ISharedObjectContext

org.eclipse.ecf.core.sharedobject.ISharedObjectContext
Context reference provided to all ISharedObjects upon initialization. Implementers of this interface provide a runtime context for ISharedObject instances. Upon initialization within a container (see {@link ISharedObject#init(ISharedObjectConfig)}, ISharedObject instances can access an instance of this context by calling {@link ISharedObjectConfig#getContext()}. They then can have access to the functions provided by this context object for use in implementing their behavior. @see ISharedObject#init @see ISharedObjectConfig#getContext()
