Class Description

                                                                      
 THashTable                                                           
                                                                      
 THashTable implements a hash table to store TObject's. The hash      
 value is calculated using the value returned by the TObject's        
 Hash() function. Each class inheriting from TObject can override     
 Hash() as it sees fit.                                               
 THashTable does not preserve the insertion order of the objects.     
 If the insertion order is important AND fast retrieval is needed     
 use THashList instead.

THashTableIter(const THashTable *ht, Bool_t dir)
 Create a hashtable iterator. By default the iteration direction
 is kIterForward. To go backward use kIterBackward.

THashTableIter(const THashTableIter &iter)
 Copy ctor.

~THashTableIter()
 Delete hashtable iterator.

TObject* Next()
 Return next object in hashtable. Returns 0 when no more objects in table.

Int_t NextSlot()
 Returns index of next slot in table containing list to be iterated.

void Reset()
 Reset the hashtable iterator. Either to beginning or end, depending on
 the initial iteration direction.
