Performs stream input and output operations on pseudo-random number distribution d
.
1) Writes a textual representation of the distribution parameters and internal state to ost
as textual representation. The formatting flags and fill character of ost
are unchanged.
2) Restores the distribution parameters and internal state with data read from ist
. The formatting flags of ist
are unchanged. The data must have been written using a stream with the same locale, CharT
and Traits
template parameters, otherwise the behavior is undefined. If bad input is encountered, ist.setstate(std::ios::failbit) is called, which may throw std::ios_base::failure. d
is unchanged in that case.
[edit] Parameters
ost | - | output stream to insert the data to |
ist | - | input stream to extract the data from |
d | - | pseudo-random number distribution |
[edit] Return value
1) ost
2) ist
[edit] Exceptions
1) (none)
2) may throw std::ios_base::failure on bad input.
