Information technology. Programming languages, their environments and system software interfaces. Guidelines for language bindings
信息技术 编程语言及其环境和系统软件接口 语言绑定指南
BS PD ISO/IEC TR 10182:2016 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 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 carries 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 independent. 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 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 another, 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 facility's
functional interface. This allows a program written in the language 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 are 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, 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 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 FORTRAN, 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.Cross References:ISO/IEC 1539-1:2010ISO/IEC 1989:2014ISO 6373:1984ISO 7185:1990ISO/IEC 7942-1ISO 8651-1:1988ISO 8651-2:1988ISO 8651-3:1988ISO/IEC 8651-4:1995ISO/IEC 8652:2012ISO 8805:1988ISO 8907:1987ISO/IEC 9075-1ISO/IEC 9075-2ISO/IEC 9075-3ISO/IEC 9075-4ISO/IEC 9075-11ISO/IEC 9593-1ISO/IEC 9593-3ISO/IEC 9593-4ISO/IEC 9899:2011ISO/IEC 10206:1991All current amendments available at time of purchase are included with the purchase of this document.
