class TOrdCollection: public TSeqCollection


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.

Function documentation

TOrdCollection(Int_t capacity = kDefaultCapacity)
 Create an ordered collection.
 Delete the collection. Objects are not deleted unless the TOrdCollection
 is the owner (set via SetOwner()).
void AddAt(TObject* obj, Int_t idx)
 Insert object at position idx in the collection.
void AddFirst(TObject* obj)
 Insert object at beginning of collection.
void AddLast(TObject* obj)
 Add object at the end of the collection.
void AddBefore(const TObject* before, TObject* obj)
 Insert object before object before in the collection.
void AddAfter(const TObject* after, TObject* obj)
 Insert object after object after in the collection.
TObject * After(const TObject* obj) const
 Return the object after object obj. Returns 0 if obj is last
 in collection.
TObject * At(Int_t idx) const
 Returns the object at position idx. Returns 0 if idx is out of range.
TObject * Before(const TObject* obj) const
 Returns the object before object obj. Returns 0 if obj is first
 in collection.
void Clear(Option_t* option = "")
 Remove all objects from the collection. Does not delete the objects
 unless the TOrdCollection is the owner (set via SetOwner()).
void Delete(Option_t* option = "")
 Remove all objects from the collection AND delete all heap based objects.
TObject * First() const
 Return the first object in the collection. Returns 0 when collection
 is empty.
TObject ** GetObjectRef(const TObject* obj) const
 return address of pointer obj
TObject * Last() const
 Return the last object in the collection. Returns 0 when collection
 is empty.
Bool_t IllegalIndex(const char* method, Int_t idx) const
 Return true when index out of bounds and print error.
Int_t IndexOf(const TObject* obj) const
 Return index of object in collection. Returns -1 when object not found.
 Uses member IsEqual() to find object.
void Init(Int_t capacity)
 Initialize ordered collection.
TIterator * MakeIterator(Bool_t dir = kIterForward) const
 Return an ordered collection iterator.
void MoveGapTo(Int_t newGapStart)
 Move gap to new position. Gap needs to be moved when objects are
 inserted not at the end.
void PutAt(TObject* obj, Int_t idx)
 Put object at index idx. Overwrites what was at idx before.
TObject * RemoveAt(Int_t idx)
 Remove object at index idx.
TObject * Remove(TObject* obj)
 Remove object from collection.
void SetCapacity(Int_t newCapacity)
 Set/change ordered collection capacity.
void Sort()
 If objects in collection are sortable (i.e. IsSortable() returns true
 for all objects) then sort collection.
Int_t BinarySearch(TObject* obj)
 Find object using a binary search. Collection must first have been
Bool_t LowWaterMark() const
Int_t PhysIndex(Int_t idx) const
{ return (idx < fGapStart) ? idx : idx + fGapSize; }
Int_t LogIndex(Int_t idx) const
{ return (idx < fGapStart) ? idx : idx - fGapSize; }
TOrdCollection(const TOrdCollection& )
TOrdCollection& operator=(const TOrdCollection& )
