std::experi...ic_allocator(3) C++ Standard Libarystd::experi...ic_allocator(3) NAME std::experimental::pmr::polymorphic_allocator - std::experimen- tal::pmr::polymorphic_allocator Synopsis Defined in header <experimental/memory_resource> template< class T > (library fundamen- tals TS) class polymorphic_allocator; The class template std::experimental::pmr::polymorphic_allocator is an Allocator whose allocation behavior depends on the memory resource it is con- structed with. Thus, different instances of polymorphic_allocator can exhibit en- tirely different allocation behavior. This runtime polymorphism allows objects using polymorphic_allocator to behave as if they used different allocator types at run time despite the identical static allocator type.
