Class Description

 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.                                  




TMapIter(const TMap *m, Bool_t dir)
 Create a map iterator. Use dir to specify the desired iteration direction.

TMapIter(const TMapIter &iter)
 Copy ctor.

 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.
