C++ named requirements: SeedSequence (od C++11)
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.
Requirements
S
is a SeedSequence type.q
is an object of S andr
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 anstd::initializer_list<T>
.rb
,re are mutable LegacyRandomAccessIterators with a value_type of unsigned integer values of at least 32 bits.ob
is an 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() ) |
