Class Description

                                                                      
 TOrdCollection                                                       
                                                                      
 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.

TIterator & operator=(const TIterator &rhs)

 Overridden assignment operator.

TOrdCollectionIter & operator=(const TOrdCollectionIter &rhs)

 Overloaded assignment operator.

TObject * Next()

 Return next object in collection. Returns 0 when no more objects in
 collection.

void Reset()

 Reset collection iterator.

TOrdCollectionIter()

{ }

~TOrdCollectionIter()

{ }

const TCollection * GetCollection()

{ return fCol; }
