Function documentation

TMapIter(const TMap* map, Bool_t dir = kIterForward)
 Create a map iterator. Use dir to specify the desired iteration direction.
TMapIter(const TMapIter& iter)
 Copy ctor.
TIterator & operator=(const TIterator& rhs)
 Overridden assignment operator.
TMapIter & operator=(const TMapIter& rhs)
 Overloaded assignment operator.
~TMapIter()
 Map iterator dtor.
TObject * Next()
 Returns the next key from a map. Use TMap::GetValue() to get the value
 associated with the key. Returns 0 when no more items in map.
void Reset()
 Reset the map iterator.
Bool_t operator!=(const TIterator& aIter) const
 This operator compares two TIterator objects.
Bool_t operator!=(const TMapIter& aIter) const
 This operator compares two TMapIter objects.
TObject * operator*() const
 Return pointer to current object (a TPair) or nullptr.
TMapIter()
{ }
const TCollection * GetCollection() const
{ return fMap; }
