namespace boost{ template <class charT, class implementationT = sensible_default_choice> struct regex_traits : public implementationT { regex_traits() : implementationT() {} }; template <class charT> struct c_regex_traits; template <class charT> class cpp_regex_traits; template <class charT> class w32_regex_traits; } // namespace boost
The class regex_traits is
just a thin wrapper around an actual implementation class, which may be one
of:
c_regex_traits: this
class is deprecated, it wraps the C locale, and is used as the default
implementation when the platform is not Win32, and the C++ locale is
not available.
cpp_regex_traits: the
default traits class for non-Win32 platforms, allows the regex class
to be imbued with a std::locale instance.
w32_regex_traits: the
default traits class implementation on Win32 platforms, allows the regex
class to be imbued with an LCID.
The default behavior can be altered by defining one of the following configuration macros in boost/regex/user.hpp
c_regex_traits
the default.
cpp_regex_traits
the default.
All these traits classes fulfil the traits class requirements.
