The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some are

21、 interface Subsystem-F : System-F ; / interface Subsystem-F 2) New Appendix I Add the following new non-normative appendix: Appendix I User guide for bulk attribute retrieval This appendix provides additional information about the TMN CORBA framework intended to help those implementing systems that

22、conform to the framework Recommendations. The top-most managed object facade, Managedobject-F, defines two operations that enable a managing system to retrieve multiple attributes from managed objects in one operation. The first, attributesGet, retrieves attributes from a single managed object. The

23、second, UttributesBulkGet, can be used to retrieve multiple attributes from multiple managed objects of the same type. The signatures of these operations are shown below: ManagedObjectValueType attributesGet ( in NameType name, inout StringSetType attributeNames) raises (ApplicationError); boolean a

24、ttributesBulkGet ( in Name Set Type names , in StringSetType attributeNames, in unsigned short howMany , out AttributesGetResultSet attributes, out AttributesGetResultIterator iterator) raises (ApplicationError) ; Note that in the first operation, attributesGet, the names of the attributes requested

25、 by the managing system are submitted in the attributeNames parameter, and the names of the attributes actually returned by the managed object are also returned in the attributehrames parameter. Because the list of attributes returned by the managed object may differ from the requested list, the dou

26、t parameter UttributeNames may be changed by the managed object. Managing system implementations that wish to repeatedly use the same list of attributes will not want that list modified by the managed object. One solution to this problem is made possible by the way in which CODA ORBs exchange messag

27、es to remotely invoke methods on objects and return results. Operation parameters are passed by order, not by name. Thus, a single inout parameter can be replaced with separate in and out parameters without impacting the inter-operability of systems. This is because the in parameter will take the sa

28、me place in the invocation message as would the inout parameter, and the out parameter will take the same place in the results message as would the inout parameter. As long as the order of the parameters is not changed, the ORBs will correctly match the parameters in the messages to the parameters o

29、n the method invocations. So, the developer of an implementation using the ManagedObject-F interface may modi the IDL by replacing the UttributesGet signature above with the signature below. 2 ITU-T Rec.
