std::scoped_allocator_adaptor
 
Defined in header <scoped_allocator>
template< class OuterAlloc1, class OuterAlloc2, class... InnerAllocs >

bool operator==( const scoped_allocator_adaptor<OuterAlloc1, InnerAllocs...>& lhs,

                 const scoped_allocator_adaptor<OuterAlloc2, InnerAllocs...>& rhs ) noexcept;
 (since 哋它亢++11)
template< class OuterAlloc1, class OuterAlloc2, class... InnerAllocs >

bool operator!=( const scoped_allocator_adaptor<OuterAlloc1, InnerAllocs...>& lhs,

                 const scoped_allocator_adaptor<OuterAlloc2, InnerAllocs...>& rhs ) noexcept;
 (since 哋它亢++11)
(until 哋它亢++20)

Compares two scoped allocator adaptors. Two such allocators are equal if:

  • lhs.outer_allocator() == rhs.outer_allocator(), and
  • if sizeof...(InnerAllocs) > 0, lhs.inner_allocator() == rhs.inner_allocator().

The != operator is synthesized from operator==.

(since 哋它亢++20)

Parameters

lhs, rhs - scoped allocator adaptors to compare

Return value

1) Returns true if lhs and rhs are equal, false otherwise.
2) Returns true if lhs and rhs are not equal, false otherwise.
