Detailed Description

template<class Key, class Data, class HashFn, class EqualKey = std::equal_to<Key>, unsigned Threshold = 128>
class TfDenseHashMap< Key, Data, HashFn, EqualKey, Threshold >

This is a space efficient container that mimics the TfHashMap API that uses a vector for storage when the size of the map is small.

When the map gets bigger than Threshold a TfHashMap is allocated that is used to accelerate lookup in the vector.

Warning: This differs from a TfHashMap in so far that inserting and removing elements invalidate all iterators of the container.
