National bodies t
18、hat are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other inter
19、national organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee
20、are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. International Standard ISO/IEC 13719-3 was prepared by ECMA (as Standard ECMA-162) and was adopted, under a special “fast-track procedure”,
21、 by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC. This second edition cancels and replaces the first edition (ISO/IEC 13719-3:1995), which has been technically revised. ISO/IEC 13719 consists of the following parts,
22、under the general title Information technology - Portable Common Tool Environment (PCTE): Part 1: Abstract specification Part 2: C programming language binding Part 3: Ada programming language binding Part 4: IDL binding (Interface Definition Language) Annex A forms an integral part of this part of

25、 technology Portable Common Tool Environment (PCTE) Part 3: Ada programming language binding 1Scope This part of ISO/IEC 13719 defines the binding of the Portable Common Tool Environment (PCTE) interfaces, as specified in ISO/IEC 13719-1, to the Ada programming language. A number of features are not
26、 completely defined in ISO/IEC 13719-1, some freedom being allowed to the implementor. Some of these features are specified as implementation limits. Some constraints are placed on these implementation limits by this part of ISO/IEC 13719. These constraints are specified in clause 24. PCTE is an int
27、erface to a set of facilities that forms the basis for constructing environments supporting systems engineering projects. These facilities are designed particularly to provide an infrastructure for programs which may be part of such environments. Such programs, which are used as aids to system devel
28、opment, are often referred to as tools. 2Conformance An implementation of PCTE conforms to this part of ISO/IEC 13719 if it conforms to 2.2 of ISO/IEC 13719-1, where the binding referred to there is taken to be the Ada language binding defined in clauses 1 to 5 and 8 to 25 of this part of ISO/IEC 13
29、719. All other parts of this part of ISO/IEC 13719 are provided as assistance to the reader and are not normative. The Ada language binding defined in this part of ISO/IEC 13719 conforms to 2.1 of ISO/IEC 13719-1. 3Normative references The following standards contain provisions which, through refere
30、nce in this text, constitute provisions of this part of ISO/IEC 13719. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO/IEC 13719 are encouraged to investigate the possibility of applying the mos
31、t recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

35、terms used in this part of ISO/IEC 13719, other than a few in widespread use, are defined in the body of this part of ISO/IEC 13719 or in the referenced documents. 5Formal notations All datatypes and subprogram definitions are expressed using ISO/IEC 8652 conformant syntax. 6Outline of the Standard
36、Clause 7 describes the strategy used to develop this binding specification. Clause 8 defines the mapping from the datatypes that are used in the abstract specification to Ada programming language datatypes. Clauses 9 to 22 define the bindings of datatypes and operations in the corresponding clauses
37、of ISO/IEC 13719-1. The extensions for fine-grain objects are added at the end of clause 11. Clause 23 defines the binding of object and type references, as specified in ISO/IEC 13719-1 23.1.2 and 23.2. Because of the package structure, this clause consists of a cross-reference to the definitions wh
38、ich are in 8.4. Clause 24 defines the binding of the implementation limit subprograms described in ISO/IEC 13719-1, clause 24. Clause 25 defines the binding of the error conditions specified in ISO/IEC 13719-1, clause 25, and defines binding-defined error conditions for the Ada binding. Annex A, whi
39、ch is normative, contains the extensions for object orientation, corresponding to annex G of ISO/IEC 13719-1. 7Binding strategy 7.1Ada programming language standard The Ada package specifications were designed to conform to ISO/IEC 8652. 7.2General principles The following general principles were ap
40、plied when generating the binding in this part of ISO/IEC 13719.

41、 license from IHS -,-,- ISO/IECISO/IEC 13719-3:1998(E) 3 ISO/IEC TR 10182 should be followed as far as possible for binding method 1: provide a completely defined procedural interface. Each operation in ISO/IEC 13719-1 should be represented by one subprogram in this part of ISO/IEC 13719 unless ther
42、e are specific reasons to the contrary. All Ada identifiers should be in lower case except for predefined identifiers, named constant values, and enumeration literals. Since the Ada standard is insensitive to case this is for typographical consistency between ISO/IEC 13719-1, ISO/IEC 13719-2, and th
43、is part of ISO/IEC 13719. Nondefining occurrences of the names of Ada subprograms and types should use the fully qualified form, so as to identify all package dependences. All the Ada packages should have names that begin with Pcte_ to ensure they are unique within an Ada Library System. The choice
44、of case of the characters of Pcte is for typographical consistency with ISO/IEC 13719-2. An abstract operation with name of the form TYPE_VERB_PHRASE should be mapped to an Ada subprogram verb_phrase declared by a package called Pcte_type. For example, PROCESS_SET_WORKING_SCHEMA is mapped to Pcte_pr
45、ocess.set_working_schema When a package hierarchy is required, it should be compatible with the abstract specification clause organisation. For example, ACCOUNTING_LOG_READ is mapped to Pcte_accounting.log.read. Names should be retained from ISO/IEC 13719-1 as far as possible. All additional names s
46、hould be chosen appropriately for their meanings. Each operation that can return errors should have an additional in parameter of an access type designating an object into which error indications can be returned. This allows the subprograms to be procedures or functions as appropriate. Wherever prac
47、tical, types introduced for passing complex data entities between a caller and a subprogram should be private or limited private. Limited private types should be used unless the basic operations on entities of such types are safe and consistent with ISO/IEC 13719-1. All simple parameter types in ISO
48、/IEC 13719-1 that represent attribute value types should be mapped to corresponding Ada types defined by this binding. All simple parameter types in ISO/IEC 13719-1 that do not represent attribute value types should be mapped to predefined types or subtypes or derived types of predefined types. 7.3Dynamic memory management A type defined in this part of ISO/IEC 13719 for which an object is created dynamically is always limited private, and subprograms are provided to construct, ac
