TIter

Class Description

                                                                      
 Collection abstract base class. This class describes the base        
 protocol all collection classes have to implement. The ROOT          
 collection classes always store pointers to objects that inherit     
 from TObject. They never adopt the objects. Therefore, it is the     
 user's responsability to take care of deleting the actual objects    
 once they are not needed anymore. In exceptional cases, when the     
 user is 100% sure nothing else is referencing the objects in the     
 collection, one can delete all objects and the collection at the     
 same time using the Delete() function.                               
                                                                      
 Collections can be iterated using an iterator object (see            
 TIterator). Depending on the concrete collection class there may be  
 some additional methods of iterating. See the repective classes.     
                                                                      
 TCollection inherits from TObject since we want to be able to have   
 collections of collections.                                          
                                                                      
 In a later release the collections may become templatized.
