Reinitializes the internal state of the underlying engine using a new seed value.
1) Seeds the underlying engine with the default seed value. Effectively callse.seed(), wheree is the underlying engine.
2) Seeds the underlying engine with the seed valuevalue. Effectively callse.seed(value), wheree is the underlying engine.
3) Seeds the underlying engine with the seed sequenceseq. Effectively callse.seed(seq), wheree is the underlying engine.
This overload participates in overload resolution only if
SeedSeq
satisfies the requirements of
SeedSequence.
[edit]Parameters
value | - | seed value to use in the initialization of the internal state of the underlying engine |
seq | - | seed sequence to use in the initialization of the internal state of the underlying engine |
[edit]Exceptions
3) If
SeedSeq
is not
std::seed_seq, throws the exceptions thrown by the
seq.generate
call.
