shuffle_order_engine();
 (1) (since C++11)
explicit shuffle_order_engine( result_type s );
 (2) (since C++11)
template < class SeedSeq >
explicit shuffle_order_engine( SeedSeq& seq ) ;
(3) (since C++11)
explicit shuffle_order_engine( const Engine& e );
(4) (since C++11)
explicit shuffle_order_engine( Engine&& e );
 (5) (since C++11)

Constructs new pseudo-random engine adaptor.

1) Default constructor. The underlying engine is also default-constructed.
2) Constructs the underlying engine with s.
3) Constructs the underlying engine with seed sequence seq.
This overload participates in overload resolution only if Sseq satisfies the requirements of SeedSequence
4) Constructs the underlying engine with a copy of e.
5) Move-constructs the underlying engine with e. e

Parameters

s - integer value to construct the underlying engine with
seq - seed sequence to construct the underlying engine with
e - pseudo-random number engine to initialize with

Exceptions

3) If SeedSeq is not std::seed_seq, throws the exceptions thrown by the seq.generate

Example

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 2181 C++11 overload (3) would not throw even if the seq.generate call throws propagates the exception
