Description copied from interface: ExportService

export to clients an internal service provided by a subcomponent Composites generally rename the export method to allow the discrimination among exported services (overload is not possible since there is only a return type). After the export, a client component may bind to the service, the binding crosscuts the composite boundary. It is possible to filter the service by promoting the inner service to the enclosing composite, as a provided service (in this case, the service is *not* exported).

Specified by:

exportService in interface ExportService

Returns:

the exported service

Throws:

ServiceExportException - if the export is not allowed
