const_iterator	constFind (const int &key) const
	Returns an iterator pointing to the item with the key in the hash. More...

bool	contains (const int &key) const

iterator	end ()
	Returns an STL-style iterator pointing to the imaginary item after the last item in the hash. More...

iterator	find (const int &key)
	Returns an iterator pointing to the item with the key in the hash. More...

const_iterator	find (const int &key) const
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. More...

	Assigns other to this hash and returns a reference to this hash. More...

bool	operator== (const QHash< int, ObjectRef > &other) const

ObjectRef &	operator[] (const int &key)
	Returns the value associated with the key as a modifiable reference. More...
