    std::scoped_allocator_adaptor
    Definiert im 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 ;
    		(seit 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 ;
    		(seit C++11)
    (bis C++20)

    Vergleicht zwei Scoped-Allocator-Adapter. Zwei solche Allokatoren sind gleich, wenn:

    • lhs. outer_allocator ( ) == rhs. outer_allocator ( ) , und
    • falls sizeof... ( InnerAllocs ) > 0 , lhs. inner_allocator ( ) == rhs. inner_allocator ( ) .

    Der != -Operator wird synthetisiert aus operator== .

    		(seit C++20)

    Parameter

    lhs, rhs - Scoped-Allocator-Adapter zum Vergleichen

    Rückgabewert

    1) Gibt true zurück, falls lhs und rhs gleich sind, andernfalls false .
    2) Gibt true zurück, wenn lhs und rhs nicht gleich sind, false andernfalls.
