class TOrdCollectionIter: public TIterator


TOrdCollection

Ordered collection. An ordered collection has TList insertion
mantics but is implemented using an array of TObject*'s. It us
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.

Function documentation

TOrdCollectionIter(const TOrdCollection* col, Bool_t dir = kIterForward)

 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(const TOrdCollectionIter& iter)

{ }

~TOrdCollectionIter()

{ }

const TCollection * GetCollection()

{ return fCol; }
