SeedSequence
C++概念：SeedSequence
阿seed sequence是一个在0≤i<232范围内产生无符号整数值i的对象。
基于消耗的整数数据范围。
所需
S是种子序列。
q是S和r的潜在常量对象S...
T是result_type...
ib，，，ie是InputIterator斯带着value_type至少32位的无符号整数值。
- il是std::initializer_list<T>...
rb，，，re是可变RandomAccessIterator斯带着value_type至少32位的无符号整数值。
ob是OutputIterator...
| 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 default values as other objects of type S | constant |
| S(ib,ie) | | Creates a seed sequence based on the 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()) |
