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 operator!=(const TIterator &aIter)

 This operator compares two TIterator objects.

bool operator!=(const TMapIter &aIter)

 This operator compares two TMapIter objects.

TObject * operator*()

 Return pointer to current object (a TPair) or nullptr.

TMapIter(const TMapIter& iter)

{ }

const TCollection * GetCollection()

{ return fMap; }
