Public member functions RWTIsvSlist<T>* container() const;
Returns a pointer to the collection over which this iterator is iterating.
T* findNext(RWBoolean
(*testFun)(const T*, void*),
void*);
Advances the iterator to the first link for which the tester function pointed to
by testFun returns TRUE and returns it, or nil if there is no such link.
void insertAfterPoint(T* a);
Inserts the link pointed to by a into the iterator's associated collection in the
position immediately after the iterator's current position.
T* key() const;
Returns the link at the iterator's current position. Returns nil if the iterator is
not valid.
T* remove();
Removes and returns the current link from the iterator's associated collection.
Returns nil if unsuccessful. Afterwards, if successful, the iterator will be
positioned at the element immediately before the removed link. This function
is relatively inefficient for a singly-linked list.
T* removeNext(RWBoolean
(*testFun)(const T*, void*),
void*);
Advances the iterator to the first link for which the tester function pointed to
by testFun returns TRUE , removes and returns it. Returns FALSE if
unsuccessful. Afterwards, if successful, the iterator will be positioned at the
element immediately before the removed element.
void reset();
Resets the iterator to the state it had immediately after construction.
void reset(RWTIsvSlist<TL>& c);
Resets the iterator to iterate over the collection c .
