template<class CharT, class OutputIterator = std::ostreambuf_iterator<CharT>>
class boost::chrono::duration_put< CharT, OutputIterator >
- Template Parameters
-
ChatT | a character type |
OutputIterator | a model of OutputIterator |
The duration_put
facet provides facilities for formatted output of duration values. The member function of duration_put
take a duration and format it into character string representation.
template<class CharT, class OutputIterator = std::ostreambuf_iterator<CharT>>
template<typename Rep , typename Period >
- Parameters
-
s | an output stream iterator |
ios | a reference to a ios_base |
fill | the character used as filler |
d | the duration |
pattern | begin of the formatting pattern |
pat_end | end of the formatting pattern |
Steps through the sequence from pattern
to pat_end
, identifying characters that are part of a pattern sequence. Each character that is not part of a pattern sequence is written to s
immediately, and each pattern sequence, as it is identified, results in a call to put_value
or put_unit
; thus, pattern elements and other characters are interleaved in the output in the order in which they appear in the pattern. Pattern sequences are identified by converting each character c
to a char
value as if by ct.narrow(c,0)
, where ct
is a reference to ctype<charT>
obtained from ios.getloc()
. The first character of each sequence is equal to ''
, followed by a pattern specifier character spec
, which can be 'v'
for the duration value or 'u'
for the duration unit. . For each valid pattern sequence identified, calls put_value(s, ios, fill, d)
or put_unit(s, ios, fill, d)
.
An iterator pointing immediately after the last character produced.
