template< class OutputIt >
void param( OutputIt dest ) const;
(since C++11)
void param( OutputIt dest ) const;
Copies the stored seeds to the range beginning with dest. Equivalent to std::copy (v .begin(), v .end(), dest);.
If values of type result_type are not writable to dest, the program is ill-formed.
If OutputIt does not satisfy the requirements of LegacyOutputIterator, the behavior is undefined.
[edit] Parameters
dest
-
the beginning iterator of the output range
[edit] Exceptions
Only throws the exceptions thrown by the operations on dest.
[edit] Example
Run this code
#include <iostream> #include <iterator> #include <random> int main() { std::seed_seq s1 = {-1, 0, 1}; s1.param(std::ostream_iterator <int>(std::cout, " ")); }
Output:
-1 0 1
[edit] Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
|---|---|---|---|
| LWG 2180 | C++11 | seed_seq::param is non-throwing
|
it may throw exceptions |
