class TMapIter: public TIterator


TMap

TMap implements an associative array of (key,value) pairs using a
THashTable for efficient retrieval (therefore TMap does not conserve
the order of the entries). The hash value is calculated
using the value returned by the keys Hash() function. Both key and
value need to inherit from TObject.

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.

TMapIter(const TMapIter& iter)

{ }

const TCollection * GetCollection()

{ return fMap; }
