    6、 Rec. ITU-T Z.107 (04/2016) i Recommendation ITU-T Z.107 Specification and Description Language Object-oriented data in SDL-2010 Summary Recommendation ITU-T Z.107 defines the object-oriented data features of the Specification and Description Language building on the foundation of the data definitio

    7、ns and expressions defined in Recommendation ITU-T Z.104. Together with Recommendations ITU-T Z.100, ITU-T Z.101, ITU-T Z.102, ITU-T Z.103, ITU-T Z.104, ITU-T Z.105 and ITU-T Z.106, this Recommendation is part of a reference manual for the language. The language defined in this Recommendation partia

    8、lly overlaps features of the language included in Basic SDL-2010 in Recommendation ITU-T Z.101 and used in Comprehensive SDL-2010 in Recommendation ITU-T Z.102, and the features of Recommendations ITU-T Z.103 and ITU-T Z.104. Coverage The Specification and Description Language has concepts for behav

    9、iour, data description and (particularly for larger systems) structuring. The basis of behaviour description is extended finite state machines communicating by messages. Data description is based on data types for values. The basis for structuring is hierarchical decomposition and type hierarchies.

    10、Though a distinctive feature of the Specification and Description Language is the graphical representation, the data and expression language is textual. Features to encode and decode data communicated by channels, define data types with values and operations, variables (including parameters) based o

    11、n data types and expression actions that use the data types have been defined in previous Recommendations. This Recommendation covers the features of the language used to provide object-oriented, hierarchical abstraction to allow the representation of larger and data-intensive systems. This Recommen

    12、dation does not always provide a canonical syntax, but by applying the Model descriptions given, a specification can be transformed to Basic SDL-2010 defined in Recommendation ITU-T Z.101, except in those cases where additional abstract syntax is added in this Recommendation. Applications The Specif

    13、ication and Description Language is applicable within standards bodies and industry. The main application areas for which the Specification and Description Language has been designed are stated in Recommendation ITU-T Z.100, but the language is generally suitable for describing reactive systems. The

    14、 range of applications is from requirement description to implementation. The features of the language defined in Recommendation ITU-T Z.107 are essential for scalable description of data-intensive systems using object-oriented abstractions.

ITU-T Z.107 (04/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologie

    17、s (ICTs). The ITU Telecommunication 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 Telecommunic

    18、ation Standardization Assembly (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

    19、information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating

    20、 agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or

    21、 some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice

    22、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 ITU members or others outside of the Recommendation development

    23、 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, implementers are cautioned that this may not represent the latest information and are therefore st

ITU-T Z.107 (04/2016) Introduction Status/Stability This Recommendation is part of the ITU-T Z.100 to ITU-T Z.107 series of Recommendations that give the

    27、 complete language reference manual for SDL-2010. The text of this Recommendation is stable. For more details see Recommendation ITU-T Z.100. Rec. ITU-T Z.107 (04/2016) 1 Recommendation ITU-T Z.107 Specification and Description Language Object-oriented data in SDL-2010 1 Scope This Recommendation de

    28、fines the object-oriented data features of the Specification and Description Language. The features defined in this document include: polymorphic object-oriented data including virtual methods, multiple inheritance of abstract types, run-time type identification and type coercion, as well as accessi

    29、ng data values by references. Without these features the language would afford limited scalability and be unsuitable for the definition of real-time embedded software applications. For this reason, specifications in the Specification and Description Language use ITU-T Z.107 features. Together with I

    30、TU-T Z.100, ITU-T Z.101, ITU-T Z.102, ITU-T Z.103, ITU-T Z.104, ITU-T Z.105 and ITU-T Z.106, this Recommendation forms a reference manual for the language. 1.1 Objective The objective of this Recommendation is to fully define the object-oriented data related features of the Specification and Descrip

    31、tion Language. Some of the ITU-T Z.107 material is also in ITU-T Z.100, ITU-T Z.101 and ITU-T Z.104. These definitions should be entirely consistent. The descriptions in ITU-T Z.100 and ITU-T Z.101 are overviews to enable data to be used with other features of SDL-2010. The ITU-T Z.104 definition is

    32、 intended to be complete (with the exception of definition of data types in ASN.1 modules see ITU-T Z.105). The ITU-T Z.107 definition extends the language with object-oriented data. 1.2 Application This Recommendation is part of the reference manual for the Specification and Description Language. T

    33、he use of object-oriented data is fundamental to the description of scalable and efficient real-time embedded applications. Thus, it is almost certain that some features defined in Recommendation ITU-T Z.107 will appear in any specification of applications in SDL-2010. 2 References The following ITU
