比较二个 scoped_allocator_adaptors 。若满足下列条件则二个这种分配器相等:
- lhs.outer_allocator() == rhs.outer_allocator() ,且
- 若 sizeof...(InnerAllocs) > 0 ,则 lhs.inner_allocator() == rhs.inner_allocator() 。
参数
lhs, rhs | - | 要比较的 scoped_allocator_adaptors |
返回值
1) 若
lhs
与 rhs
相等,则返回 true ,否则返回 false 。2) 若
lhs
与 rhs
不相等,则返回 true ,否则返回 false 。
