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 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 ) noexcept ;
(since C++11)
(until C++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 C++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.
