operators (std::scoped_allocator_adaptor)
template< class OuterAlloc1, class OuterAlloc2, class... InnerAllocs > bool operator==( const scoped_allocator_adaptor<OuterAlloc1, InnerAllocs...>& lhs, const scoped_allocator_adaptor<OuterAlloc2, InnerAllocs...>& rhs ); | | (since C++11) |
|---|---|---|
template< class OuterAlloc1, class OuterAlloc2, class... InnerAllocs > bool operator!=( const scoped_allocator_adaptor<OuterAlloc1, InnerAllocs...>& lhs, const scoped_allocator_adaptor<OuterAlloc2, InnerAllocs...>& rhs ); | | (since C++11) |
比较两个作用域分配器适配器。如果下列情况下，两个这样的分配器是相等的：
lhs.outer_allocator() == rhs.outer_allocator()，和
- 如果
sizeof...(InnerAllocs) > 0，，，lhs.inner_allocator() == rhs.inner_allocator()...
参数
lhs, rhs | - | scoped allocator adaptors to compare |
|---|
返回值
1%29true如果lhs和rhs是平等的，false否则。
2%29true如果lhs和rhs是不平等的，false否则。
例外
