Public Member Functions

 HashSet ()
 Construct empty.
 
 HashSet (const HashSet< T > &set)
 Construct from another hash set.
 
 HashSet (const std::initializer_list< T > &list)
 Aggregate initialization constructor.
 
 ~HashSet ()
 Destruct.
 
HashSetoperator= (const HashSet< T > &rhs)
 Assign a hash set.
 
HashSetoperator+= (const T &rhs)
 Add-assign a value.
 
HashSetoperator+= (const HashSet< T > &rhs)
 Add-assign a hash set.
 
bool operator== (const HashSet< T > &rhs) const
 Test for equality with another hash set.
 
bool operator!= (const HashSet< T > &rhs) const
 Test for inequality with another hash set.
 
Iterator Insert (const T &key)
 Insert a key. Return an iterator to it.
 
Iterator Insert (const T &key, bool &exists)
 Insert a key. Return an iterator and set exists flag according to whether the key already existed.
 
void Insert (const HashSet< T > &set)
 Insert a set.
 
Iterator Insert (const ConstIterator &it)
 Insert a key by iterator. Return iterator to the value.
 
bool Erase (const T &key)
 Erase a key. Return true if was found.
 
Iterator Erase (const Iterator &it)
 Erase a key by iterator. Return iterator to the next key.
 
void Clear ()
 Clear the set.
 
void Sort ()
 Sort keys. After sorting the set can be iterated in order until new elements are inserted.
 
bool Rehash (unsigned numBuckets)
 Rehash to a specific bucket count, which must be a power of two. Return true if successful.
 
Iterator Find (const T &key)
 Return iterator to the key, or end iterator if not found.
 
ConstIterator Find (const T &key) const
 Return const iterator to the key, or end iterator if not found.
 
bool Contains (const T &key) const
 Return whether contains a key.
 
Iterator Begin ()
 Return iterator to the beginning.
 
ConstIterator Begin () const
 Return iterator to the beginning.
 
Iterator End ()
 Return iterator to the end.
 
ConstIterator End () const
 Return iterator to the end.
 
const T & Front () const
 Return first key.
 
const T & Back () const
 Return last key.

NodeInsertNode (Node *dest, const T &key)
 Insert a node into the list. Return the new node.
 
NodeEraseNode (Node *node)
 Erase a node from the list. Return pointer to the next element, or to the end if could not erase.
 
NodeReserveNode ()
 Reserve a node.
 
NodeReserveNode (const T &key)
 Reserve a node with specified key.
 
void FreeNode (Node *node)
 Free a node.

 Compute a hash based on the key and the bucket size.
 

Static Private Member Functions

static bool CompareNodes (Node *&lhs, Node *&rhs)
 Compare two nodes.
