NAME

operator==,!=(std::experimental::pmr::polymorphic_allocator) - operator==,!=(std::experimental::pmr::polymorphic_allocator)

Synopsis

template< class T1, class T2 >
bool operator==( const polymorphic_allocator<T1>& lhs, const polymorphic_allocator<T2>& rhs ) noexcept;
template< class T1, class T2 >
bool operator!=( const polymorphic_allocator<T1>& lhs, const polymorphic_allocator<T2>& rhs ) noexcept;

Compares two polymorphic allocators. Two polymorphic allocators compare equal if their underlying memory resource compares equal.
1) Returns *lhs.resource() == *rhs.resource()
2) Returns !(lhs == rhs)

Parameters

lhs, rhs - polymorphic allocators to compare

Return value

1) *lhs.resource() == *rhs.resource()
2) !(lhs == rhs)
