use of org.osgi.service.blueprint.container.ComponentDefinitionException in project aries by apache.

the class Parser method handleCustomScope.

     * require that characters presence.

     * @param scope Value of scope attribute
     * @param bean DOM element for bean associated to this scope 
     * @return Metadata as processed by NS Handler.
     * @throws ComponentDefinitionException if an undeclared prefix is used, 
     *           if a namespace handler is unavailable for a resolved prefix, 
     *           or if the resolved prefix results as the blueprint namespace.
