Expression | Return type | Assertion/note pre-/post-condition |
X::char_type | charT | The character container type used in the implementation of class
template basic_regex. |
X::string_type | basic_string<charT> | |
X::locale_type | A copy constructible type | A type that represents the locale used by the traits class. |
X::char_class_type | A bitmask type representing a particular character classification. | |
X::length(p) | size_t | Complexity is
linear in i . |
v.translate(c) | X::char_type | Returns a character such that for any character d that is to
be considered equivalent to c then v.translate(c) == v.translate(d). |
v.translate_nocase(c) | X::char_type | For all characters C that are to be considered equivalent
to c when comparisons are to be performed without regard to
case, then v.translate_nocase(c) == v.translate_nocase(C). |
v.transform(F1, F2) | X::string_type | Returns a sort key for the character sequence designated by the
iterator range [F1, F2) such that if the character sequence
[G1, G2) sorts before the character sequence [H1, H2)
then v.transform(G1, G2) < v.transform(H1, H2). |
v.transform_primary(F1, F2) | X::string_type | Returns a sort key for the character sequence designated by the
iterator range [F1, F2) such that if the character sequence
[G1, G2) sorts before the character sequence [H1, H2)
when character case is not considered
then v.transform_primary(G1, G2) < v.transform_primary(H1, H2). |
v.lookup_collatename(F1, F2) | X::string_type | Returns a sequence of characters that represents the collating element
consisting of the character sequence designated by the iterator range
[F1, F2). Returns an empty string if the character sequence is not
a valid collating element. |
v.lookup_classname(F1, F2, b) | X::char_class_type | Converts the character sequence designated by the iterator range
[F1, F2) into a value of a bitmask type that can
subsequently be passed to isctype. Values returned from
lookup_classname can be bitwise OR'ed together; the
resulting value represents membership in either of the
corresponding character classes. If b is true, the returned bitmask is suitable for
matching characters without regard to their case. The value returned shall be independent of the case of
the characters in the sequence. |
v.isctype(c, cl) | bool | Returns true if character c is a member of
one of the character classes designated by cl,
false otherwise. |
v.value(c, I) | int | Returns the value represented by the digit c in base
I if the character c is a valid digit in base I;
otherwise returns -1. |
u.imbue(loc) | X::locale_type | |
v.getloc() | X::locale_type | Returns the current locale used by v, if any. |
