详细描述

template<typename K, typename V, typename HASH = DefaultCompare, typename HANDLER = RefCountHashMapDefaultHandler>
class maxon::RefCountHashMap< K, V, HASH, HANDLER >

Use a RefCountHashMap for cache-like use cases where a map entry shall be automatically removed when it isn't used any longer.

To add an entry to a RefCountHashMap , you have to use and store an EntryRef as in

EntryRef ref; Bool created; V* value = ref.Set(map, key, created) iferr_return ;

This will add an entry for key , and this entry will stay in the map as long as there are EntryRefs pointing to it. The map keeps track of those entries by means of reference counting.
