template<class CharT , class InputIterator = std::istreambuf_iterator<CharT>>

typedef CharT boost::chrono::time_point_get< CharT, InputIterator >::char_type

Type of character the facet is instantiated on.

template<class CharT , class InputIterator = std::istreambuf_iterator<CharT>>

typedef InputIterator boost::chrono::time_point_get< CharT, InputIterator >::iter_type

Type of iterator used to scan the character buffer.

Constructor & Destructor Documentation

template<class CharT , class InputIterator = std::istreambuf_iterator<CharT>>

boost::chrono::time_point_get< CharT, InputIterator >::time_point_get ( size_t  refs = 0 )

inlineexplicit

Construct a time_point_get facet.

Parameters

refs

Construct a time_point_get 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.

Parameters

s	start input stream iterator
end	end input stream iterator
ios	a reference to a ios_base
err	the ios_base state
d	the duration
pattern	begin of the formatting pattern
pat_end	end of the formatting pattern

Requires: [pattern,pat_end) shall be a valid range.

Effects: The function starts by evaluating err = std::ios_base::goodbit. It then enters a loop, reading zero or more characters from s at each iteration. Unless otherwise specified below, the loop terminates when the first of the following conditions holds:

• The expression pattern == pat_end evaluates to true.
• The expression err == std::ios_base::goodbit evaluates to false.
• The expression s == end evaluates to true, in which case the function evaluates err = std::ios_base::eofbit | std::ios_base::failbit.
• The next element of pattern is equal to '', followed by a conversion specifier character, the functions get_duration or get_epoch are called depending on whether the format is 'd' or 'e'. If the number of elements in the range [pattern,pat_end) is not sufficient to unambiguously determine whether the conversion specification is complete and valid, the function evaluates err = std::ios_base::failbit. Otherwise, the function evaluates s = do_get(s, end, ios, err, d). If err == std::ios_base::goodbit holds after the evaluation of the expression, the function increments pattern to point just past the end of the conversion specification and continues looping.
• The expression isspace(*pattern, ios.getloc()) evaluates to true, in which case the function first increments pattern until pattern == pat_end || !isspace(*pattern, ios.getloc()) evaluates to true, then advances s until s == end || !isspace(*s, ios.getloc()) is true, and finally resumes looping.
• The next character read from s matches the element pointed to by pattern in a case-insensitive comparison, in which case the function evaluates ++pattern, ++s and continues looping. Otherwise, the function evaluates err = std::ios_base::failbit.

Returns: s

Let facet be the time_point_units facet associated to is or a new instance of the default time_point_units_default facet.

Let epoch be the epoch string associated to the Clock using this facet. Scans i to match epoch or e is reached.

If not match before the e is reached std::ios_base::failbit is set in err. If e is reached std::ios_base::failbit is set in err.

An iterator pointing just beyond the last character that can be determined to be part of a valid epoch.
