std::linear_congruential_engine<UIntType,a,c,m>::seed
void seed( result_type value = default_seed ); | (1) | (since C++11) |
template< class SeedSeq > void seed( SeedSeq& seq ); | (2) | (since C++11) |
Sets the state of the random-number engine.
1) Right after the state is set,
*this == std::linear_congruential_engine(value) is true.
2) Right after the state is set,
*this == std::linear_congruential_engine(seq) is true.Parameters
| value | - | seed value to use to set the state |
| seq | - | seed sequence to use to set the state |
Exceptions
Complexity
1) Same as
std::linear_congruential_engine(value).
2) Same as
std::linear_congruential_engine(seq).Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
