Detailed Description

template<typename Key, class Value, class Map = std::map<Key, MemCore::WeakPtr<Value> >>
class MemCore::WeakRefMap< Key, Value, Map >

Convenience template class for mapping of keys to weak reference pointers; provides a read-only search operation using the () operator.

All objects stored in this RefMap are not kept alive.

operator()()

ValuePtr_t MemCore::WeakRefMap< Key, Value, Map >::operator() ( const Key &  K ) const

Search for an object stored in this map.

Note that this operation is ambigious, as it may find a null pointer stored in this map. If it is important to distinguish between a stored null pointer versus a key not found, then the map's find() version needs to be used.
