[[support]](support "17 Language support library") through [[exec]](exec "33 Execution control library") and[[depr]](depr "Annex D (normative) Compatibility features") do not specify the representation of classes, and intentionally
|
||
omit specification of [class members](class.mem "11.4 Class members [class.mem]")[.](#1.sentence-1)
|
||
|
||
An implementation may
|
||
define static or non-static class members, or both, as needed to implement the
|
||
semantics of the member functions specified in [[support]](support "17 Language support library") through [[exec]](exec "33 Execution control library") and [[depr]](depr "Annex D (normative) Compatibility features")[.](#1.sentence-2)

|

|
||
For the sake of exposition,
|
||
some subclauses provide representative declarations, and semantic requirements, for
|
||
private members of classes that meet the external specifications of the classes[.](#2.sentence-1)
|
||
|
||
The declarations for such members are
|
||
followed by a comment that ends with *exposition only*, as in:streambuf* sb; // *exposition only*

An implementation may use any technique that provides equivalent observable behavior[.](#3.sentence-1)
