Detailed Description

template<class Element, class HashFn, class EqualElement = std::equal_to<Element>, unsigned Threshold = 128>
class TfDenseHashSet< Element, HashFn, EqualElement, Threshold >

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

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

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

Member Typedef Documentation

template<class Element, class HashFn, class EqualElement = std::equal_to<Element>, unsigned Threshold = 128>
typedef _Vector::const_iterator TfDenseHashSet< Element, HashFn, EqualElement, Threshold >::const_iterator

A const_iterator type for this set.

Definition at line 64 of file denseHashSet.h.

template<class Element, class HashFn, class EqualElement = std::equal_to<Element>, unsigned Threshold = 128>
typedef std::pair<const_iterator, bool> TfDenseHashSet< Element, HashFn, EqualElement, Threshold >::insert_result

Return type for insert() method.

template<class Element, class HashFn, class EqualElement = std::equal_to<Element>, unsigned Threshold = 128>
typedef _Vector::const_iterator TfDenseHashSet< Element, HashFn, EqualElement, Threshold >::iterator

An iterator type for this set. Note that this one is const as well, as we can't allow in-place modification of elements due to the potentially allocated hash map.
