Detailed Description

template<typename CharT = char>
class boost::chrono::time_point_units< CharT >

time_point_units facet gives useful information about the time_point pattern, the text associated to a time_point's epoch,

Member Typedef Documentation

template<typename CharT = char>

typedef CharT boost::chrono::time_point_units< CharT >::char_type

Type of character the facet is instantiated on.

template<typename CharT = char>

typedef std::basic_string<char_type> boost::chrono::time_point_units< CharT >::string_type

Type of character string used by member functions.

Constructor & Destructor Documentation

template<typename CharT = char>

boost::chrono::time_point_units< CharT >::time_point_units ( size_t  refs = 0 )

inlineexplicit

Construct a time_point_units facet.

Parameters

refs

Construct a time_point_units facet. If the refs argument is 0 then destruction of the object is delegated to the locale, or locales, containing it. This allows the user to ignore lifetime management issues. On the other had, if refs is 1 then the object must be explicitly deleted; the locale will not do so. In this case, the object can be maintained across the lifetime of multiple locales.

template<typename CharT = char>

virtual boost::chrono::time_point_units< CharT >::~time_point_units ( )

inlineprotectedvirtual

Destroy the facet.
