13、ation for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respe

Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of informati

15、on technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different t

21、nThis Technical Report is a compilation of the experience and knowledge gained by the members of ISO/IEC JTC1/SC22/WG11 (Techniques for Bindings) from the generation of programmers interfaces to FUNCTIONAL INTERFACE STANDARDS. Although current experience was derived from the fields of computer graph

22、ics and database management, the problems discussed are thought to be generally applicable for mappings of other functional interface standards to programming languages. This Technical Report is intendeda) to identify the problems and conflicts which shall be resolved;b) to suggest guidelines for fu

23、ture use;c) to provide scope and direction to required additional work, such as common procedural callingmechanisms and data types; andd) as a historical record of past experiences and decisions.This Technical Report is incomplete; the authors have concentrated on those areas where experience and ex

24、pertise was readily available. The ideas and issues brought forward here emerged from more than 10 years of work, and are represented in International Standards.Clause 3 of this Technical Report contains the results of a survey of current methods used for language binding development. Characteristic

25、s of each method are given, followed by reasons for the selection of the method.Application of the methods has suggested some guidelines that are presented in Clause 4. Clauses 3 and 4 contain documentation of the current state of language binding efforts; Clause 5 addresses future directions for la

26、nguage bindings.Circulation of this Technical Report is necessary at this stage, as input and discussion from representatives of ISO/IEC JTC1/SC21 (functional specification standards developers), ISO/IEC JTC1/SC24 (computer graphics standards developers), and ISO/IEC JTC1/SC22 (language standards de

27、velopers) is urgently sought. The Technical Report in its current form may be useful for those about to embark on language binding developments.

28、em software interfaces Guidelines for language bindings1 ScopeThis Technical Report is based on experience gained in the standardization of two major areas in information processing. One area covers programming languages. The other area is composed of the services necessary to an application program

29、 to achieve its goal. The services are divided into coherent groups, each referred to as a SYSTEM FACILITY, that are accessed through a FUNCTIONAL INTERFACE. The specification of a system facility, referred to as a FUNCTIONAL SPECIFICATION, defines a collection of SYSTEM FUNCTIONS, each of which car

30、ries out some well-defined service.Since in principle there is no reason why a particular system facility should not be used by a program, regardless of the language in which it is written, it is the practice of system facility specifiers to define an abstract functional interface that is language i

31、ndependent. In this way, the concepts in a particular system facility may be refined by experts in that area without regard for language peculiarities. An internally coherent view of a particular system facility is defined, relating the system functions to each other in a consistent way and relating

32、 the system functions to other layers within the system facility, including protocols for communication with other objects in the total system.However, if these two areas are standardized independently, it is not possible to guarantee that programs from one operating environment can be moved to anot

33、her, even if the programs are written in a standard programming language and use only standard system facilities. A language binding of a system facility to a programming language provides language syntax that maps the system facilitys functional interface. This allows a program written in the langu

34、age to access the system functions constituting the system facility in a standard way. The purpose of a language binding is to achieve portability of a program that uses particular facilities in a particular language. Examples of system facilities that have had language bindings developed for them a

35、re GKS, NDL, and SQL (see Bibliography). It is anticipated that further language binding development will be required. Some system facilities currently being standardized have no language bindings and additional system facilities will be standardized. There is a possibility of n m language bindings,

36、 where n is the number of languages and m the number of system facilities.The scope of this Technical Report is to classify language binding methods, reporting on particular instances in detail, and to produce suggested guidelines for future language binding standards.Note that the language bindings

37、 and the abstract facility interfaces shall have a compatible run time representation, but the abstract facility does not necessarily have to be written in the host language. For example, if the application program is using a Pascal language binding and the corresponding facility is written in FORTR

38、AN, there shall be a compatible run time representation in that operating environment. How this compatibility is achieved is outside the scope of these guidelines. This is generally a property of the operating environment defined by the implementor, and is reviewed briefly in this Technical Report.2

39、 Terms and definitions2.1 TermsABSTRACT SERVICE INTERFACE: An interface having an abstract definition that defines the format and the semantics of the function invoked independently of the concrete syntax (actual representation) of the values and the invocation mechanism.TECHNICAL REPORT ISO/IEC TR

In the context of

42、this Technical Report, the functional specification is normally a potential or actual standard. For each system function the specification defines the parameters for invocation and their effects.HOST LANGUAGE: The programming language for which a standard language binding is produced; the language i

43、n which a program is written.IDENTIFIER: Name of an object in an application program that uses a system facility.IMPLEMENTATION-DEFINED: Possibly differing between different processors for the same language, but required by the language standard to be defined and documented by the implementor.IMPLEM

44、ENTATION-DEPENDENT: Possibly differing between different processors for the same language, and not necessarily defined for any particular processor.IMPLEMENTOR: The individual or organization that realizes a system facility through software, providing access to the system functions by means of the s

A procedure has a name and a set of formal parameters with defined data types. Invoking a procedure transfers control to that procedure.PROCESSOR: A system or mecha

49、nism that accepts a program as input, prepares it for execution, and executes the process so defined with data to produce results.PROGRAMMING LANGUAGE EXTENSIONS WITH NATIVE SYNTAX or native syntax binding: The functionality of the system facilities is incorporated into the host programming language so that the system functions appear as natural parts of the language. The compiler processes the language extensions and generates the appropriate calls to the system facility functions.SYSTEM FACILITY: A coherent collection of services to be ma
