Expression | Return type | Requirement | |
g.parse(pc) | PC::iterator | Parses format-spec ([format.string])
for type T
in the range [pc.begin(), pc.end())
until the first unmatched character.
Stores the parsed format specifiers in *this and
returns an iterator past the end of the parsed range. | |
f.format(u, fc) | FC::iterator | Formats u according to the specifiers stored in *this,
writes the output to fc.out(), and
returns an iterator past the end of the output range. The output shall only depend on
u,
fc.locale(),
fc.arg(n) for any value n of type size_t,
and the range [pc.begin(), pc.end())
from the last call to f.parse(pc). |
