Describes aspects of a regular expression.
A regular expression traits class that satisfies the requirements of section [28.7].
The class regex is parameterized around a set of related types and functions used to complete the definition of its semantics. This class satisfies the requirements of such a traits class.

Imbues the regex_traits object with a copy of a new locale.
| __loc | A locale. |
| bool std::regex_traits< _Ch_type >::isctype | ( | _Ch_type | __c, |
| char_class_type | __f | ||
| ) | const |
Determines if c is a member of an identified class.
| __c | a character. |
| __f | a class type (as returned from lookup_classname). |
__c is a member of the classification represented by __f, false otherwise.| std::bad_cast | if the current locale does not have a ctype facet. |
|
inlinestatic |
Gives the length of a C-style string starting at __p.
| __p | a pointer to the start of a character sequence. |
*__p and the first default-initialized value of type char_type. In other words, uses the C-string algorithm for determining the length of a sequence of characters. | char_class_type std::regex_traits< _Ch_type >::lookup_classname | ( | _Fwd_iter | __first, |
| _Fwd_iter | __last, | ||
| bool | __icase = false |
||
| ) | const |
Maps one or more characters to a named character classification.
| __first | beginning of the character sequence. |
| __last | one-past-the-end of the character sequence. |
| __icase | ignores the case of the classification name. |
icase is true, the returned mask identifies the classification regardless of the case of the characters to be matched (for example, [[:lower:]] is the same as [[:alpha:]]), otherwise a case-dependent classification is returned. The value returned shall be independent of the case of the characters in the character sequence. If the name is not recognized then returns a value that compares equal to 0.At least the following names (or their wide-character equivalent) are supported.
| string_type std::regex_traits< _Ch_type >::lookup_collatename | ( | _Fwd_iter | __first, |
| _Fwd_iter | __last | ||
| ) | const |
Gets a collation element by name.
| __first | beginning of the collation element name. |
| __last | one-past-the-end of the collation element name. |
|
inline |
Gets a sort key for a character sequence.
| __first | beginning of the character sequence. |
| __last | one-past-the-end of the character sequence. |
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).
What this really does is provide a more efficient way to compare a string to multiple other strings in locales with fancy collation rules and equivalence classes.

Gets a sort key for a character sequence, independent of case.
| __first | beginning of the character sequence. |
| __last | one-past-the-end of the character sequence. |
Effects: if typeid(use_facet<collate<_Ch_type> >) == typeid(collate_byname<_Ch_type>) and the form of the sort key returned by collate_byname<_Ch_type>::transform(__first, __last) is known and can be converted into a primary sort key then returns that key, otherwise returns an empty string.

| int std::regex_traits< _Ch_type >::value | ( | _Ch_type | __ch, |
| int | __radix | ||
| ) | const |
Converts a digit to an int.
| __ch | a character representing a digit. |
| __radix | the radix if the numeric conversion (limited to 8, 10, or 16). |
