Class Description

 Ordered collection. An ordered collection has TList insertion        
 semantics but is implemented using an array of TObject*'s. It uses   
 less space than a TList (since there is no need for the prev and     
 next pointers), but it is more costly to insert objects (since it    
 has to create a gap by copying object pointers). TOrdCollection      
 is better than TList when objects are only added at the end of the   
 collection since no copying needs to be done.                        




TOrdCollectionIter(const TOrdCollection *col, Bool_t dir)
 Create collection iterator. By default the iteration direction
 is kIterForward. To go backward use kIterBackward.

TOrdCollectionIter(const TOrdCollectionIter &iter)
 Copy ctor.

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

void Reset()
 Reset collection iterator.
