Detailed Description

template<typename Key, typename Value, template< typename SKey, typename SValuePtr > class DeleteStrategy = CacheRemoveOnlyWhenDeleted>
struct plask::StrongCache< Key, Value, DeleteStrategy >

Cache values of type Value using Key type to index it.

It stores shared_ptr to values, so each value will be live when it's only is included in cache. Cache entries are removed on key changes (see deleteStrategy).

Template Parameters

Key	type using as index in cache (pointer to this type will be used), must be able to emit events;
Value	type for cache values, will be stored in shared_ptr;
deleteStrategy	when cache entries should be deleted: CacheRemoveOnlyWhenDeleted - when key is deleted (default), CacheRemoveOnEachChange - when key is changed, other class template which derives from plask::CacheRemoveStrategyBase and have void onEvent(typename Key::Event& evt) method - custom.
