template<class Key,class T,class Compare, class KeyContainer,class MappedContainer,class Allocator> | (since C++23) | |
Provides a transparent specialization of thestd::uses_allocator type trait forstd::flat_multimap: the container adaptor uses allocator if and only if the underlying container does.
