Programming languages. C++ Extensions for ranges
1 Scope
[intro.scope]
This document describes extensions to the C++ Programming Language (2) that permit operations on ranges of data. These extensions include changes and additions to the existing library facilities as well as the extension of one core language facility. In particular, changes and extensions to the Standard Library include:
— The formulation of the foundational and iterator concept requirements using the syntax of the Concepts TS (2 ).
— Analogues of the Standard Library algorithms specified in terms of the new concepts.
— The loosening of the algorithm constraints to permit the use of sentinels to denote the end of a range and corresponding changes to algorithm return types where necessary.
— The addition of new concepts describing range and view abstractions; that is, objects with a begin iterator and an end sentinel.
— New algorithm overloads that take range objects.
— Support of callable objects (as opposed to function objects ) passed as arguments to the algorithms.
— The addition of optional projection arguments to the a...
