C++ named requirements: SeedSequence (since C++11) (original) (raw)

A SeedSequence is an object that produces unsigned integer values i in the range 0 ≤ i < 232
based on a consumed range of integer data.

**S** is a SeedSequence type.
**q** is an object of S and **r** is a potentially constant object of S.
**T** is the result_type.
**ib**, **ie** are LegacyInputIterators with a value_type of unsigned integer values of at least 32 bits.
**il** is a std::initializer_list<T>.
**rb**, **re** are mutable LegacyRandomAccessIterators with a value_type of unsigned integer values of at least 32 bits.
**ob** is a LegacyOutputIterator.

Expression	Type	Notes	Complexity
S::result_type	T	Unsigned integer of at least 32 bits.	Compile-time
S()	Creates a seed sequence with the same initial state as other default-constructed seed sequences of type S.	Constant
S(ib, ie)	Creates a seed sequence with internal state depending on some or all supplied input bits by [ib, ie).	O(ie - ib)
S(il)	The same as S(il.begin(), il.end()).
q.generate(rb, re)	void	Fills [rb, re) with 32-bit quantities depending on the initial supplied values and potential previous calls to generate. If rb == re, it does nothing.	O(re - rb)
r.size()	size_t	The amount of 32-bit integers copied by param.	Constant
r.param(ob)	void	Copies 32-bit values to ob that would reproduce the current state of the object if passed to a constructor of S.	O(r.size())
