ITU-T Recommendation X.780 TMN guidelines for defining CORBA managed objects CORRIGENDUM 1 Source Corrigendum 1 to IT-T Recommendation X.780 (2001) was pre
9、pared by ITU-T Study Group 4 (2001-2004) and approved under the WTSA Resolution 1 procedure on 7 October 2001. ITU-T Rec. X.780 (2001)/Cor.l (10/2001) i FOREWORD The International Telecommunication Union is the United Nations specialized agency in the field of telecommunications. The ITU Telecommuni
10、cation Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembl
11、y (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which
12、fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Aministration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY
13、 RIGHTS IT draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by
14、 members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this m
15、ay not represent the latest information and are therefore strongly urged to consult the TSB patent database. o ITU 2002 All rights reserved.

19、nal package string name. 3) Subclause 5.5 In the IDL, delete the following lines: valuetype CreateErrorInfoType : ApplicationErrorInfoType public MOSetType relatedobjects; public AttributeSetType attributelist; 1; valuetype DeleteErrorInfoType : ApplicationErrorInfoType public MOSetType relatedobjec
20、ts; public AttributeSetType attributeList; 1; and replace them with the following: valuetype CreateErrorInfoType : ApplicationErrorInfoType public MONameSetType relatedobjects; public AttributeSetType attributelist; 1; valuetype DeleteErrorInfoType : ApplicationErrorInfoType public MONameSetType rel
21、atedobjects; public AttributeSetType attributelist; 1; 4) Subclause 6.3 Delete the last line of the first paragraph: Future versions of CORBA plan to allow user-defined exceptions on attribute access, and these guidelines may change to take advantage of this. AJter the $rst paragraph, add the follow
22、ing paragraph: The definition of attributes containing references to managed objects should be avoided. Instead, managed object names should be used. ITU-T Rec. X.780 (2001)/Cor.l(10/2001) 1 5) New subclause 6.3.6 Add a new subclause 6.3.6 entitled “Common Types“ as follows: 6.3.6 Commontypes A modu
23、le dening common types is found in Annex C. These types are used by more than one Recommendation. This module is used to provide a single place for the definition of these types. Additional types will be added to this module as needed. 6) Subclause 6.4 In the$rst paragraph, aJter the second sentence
24、, add the following sentence: The use of parameters containing references to managed objects, however, should be avoided. Instead, managed object names should be used 7) Subclause 6.6 After the third paragraph, add the following paragraph: In addition, for each defined conditional package, there sha
25、ll be defined a constant string that can be used in the packages attribute for managed object instances using that conditional package. To differentiate packages from different IDL files, this string must be fully qualified. For example: const string administrativestatepackage = 1itut-m3120:administ
26、rativeStatePackage11; 8) Subclause 6.9.1 Replace subclause 6.9.1 with the following: 6.9.1 Create Operations Each factory interface shall define a single operation for clients to use to create objects. The name of this operation shall be “create“ and it shall return a ManagedObject reference. This s
27、hall be used to return a reference to the newly created object, which may then be “narrowed“ by the client to the specific interface type for that object, or used directly for base class operations. The first five parameters to every create operation are always the same. Mer these come parameters fo
28、r each writeable or set-by-create attribute defined for the managed object. (A set-by-create attribute is one for which the object has no “set“ operation, but for which a value is specified on the create operation.) The names of these parameters are the same as the name of the attribute. (This is th
29、e name of an attribute accessor operation minus the ending “Get“ or “Set“.) Each create operation also has to accept parameters to set the values of any writeable or set-by-create attributes of all super- classes of the object created by the factory. Here is equipment factory: ManagedObject create(
30、in NameBindingType nameBinding, / / in MONameType superiorobject, / in string reqID, / / out MONameType name, / in StringSetType packages, / . / / . / / an example of a create operation for an module name containing Name Binding info. Name of containing object. Requested ID value for name, will be e
31、mpty if auto-naming is to be used. Entire name of newly created object. List of packages requested. Writeable and set-by-create values for Equipment superclass attributes. Writeable and set-by-create values for Equipment attributes. ITU-T Rec. X.780/Cor.l(10/2001) 9) Subclause 6.9.1.2 In the first s
32、entence of the jrst paragraph, replace the words “is a reference to“ with “is the name of.“ In the third sentence of the first paragraph, replace the words “supplied reference“ with “superior object.“ In the last sentence of the second paragraph, replace the words “reference would be null“ with “nam
33、e would be an empty string.“ 10) New subclause 6.9.1.3 Insert a new subclause 6.9.1.3 entitled “Requested ID“ and renumber the existing subclause 6.9.1.3 and subsequent subclauses. 6.9.1.3 Requested ID The third parameter is the ID requested to be assigned to the new object. This string will become
34、the ID field of the COIU3A Name Binding created in the COBA naming service for the new object. Thus, this ID string, along with the kind field contained in the name binding module, names the new object relative to the superior object. If the client supplies an empty string for this parameter, the fa
35、ctory shall automatically choose an ID value. The factory raises a dupliCateName CreateError exception if the supplied ID is a duplicate. (This means both the ID and kind fields match an existing object contained by the superior object.) 11) Subclause 6.9.1.4 Replace the contents of subclause 6.9.1.
36、4 (entitled “Name,“ and newly renumbered by the item above) with the following: The fourth parameter shall be used by the factory to return the entire name of the newly created managed object to the client. 12) Subclause 9.1 After the 8th list item, add the following list item: 9) The subsequent ite
37、ms should be renumbered. Adhere to the conditional package string constant conventions specified in 6.6. 13) Anna A In the IDL, delete the following lines: /* A SuspectObject identifies an object that may be the cause of a failure.
