void TSortedList::Add ( TObject *  obj )

virtual

Reimplemented from TList.

Referenced by AddAfter(), AddAt(), AddBefore(), AddFirst(), AddLast(), RooThresholdCategory::addThreshold(), TQueryResultManager::ApplyMaxQueries(), TProofLite::CleanupSandbox(), TProofPerfAnalysis::FillFileInfo(), TProofPerfAnalysis::FillWrkInfo(), TProofBench::GetPerfSpecs(), TProofMgrLite::GetSessionLogs(), TPluginManager::LoadHandlerMacros(), and RooThresholdCategory::RooThresholdCategory().

void TSortedList::Add ( TObject *  obj, Option_t *  opt  )

virtual

Add object in sorted list.

Uses object Compare() member to find right position and also store option. See TList::Add for explanation of usage of option.

Reimplemented from TList.

Definition at line 65 of file TSortedList.cxx.

void TSortedList::AddAfter ( const TObject *  after, TObject *  obj  )

inlinevirtual

Insert object after object after in the list.

Reimplemented from TList.

Definition at line 46 of file TSortedList.h.

void TSortedList::AddAfter ( TObjLink *  after, TObject *  obj  )

inlinevirtual

Insert object after the specified ObjLink object.

If after = 0 then add to the tail of the list. An ObjLink can be obtained by looping over a list using the above describe iterator method 3.

Reimplemented from TList.

Definition at line 47 of file TSortedList.h.

void TSortedList::AddAt ( TObject *  obj, Int_t  idx  )

inlinevirtual

Insert object at position idx in the list.

Reimplemented from TList.

Definition at line 45 of file TSortedList.h.

void TSortedList::AddBefore ( const TObject *  before, TObject *  obj  )

inlinevirtual

Insert object before object before in the list.

Reimplemented from TList.

Definition at line 48 of file TSortedList.h.

void TSortedList::AddBefore ( TObjLink *  before, TObject *  obj  )

inlinevirtual

Insert object before the specified ObjLink object.

If before = 0 then add to the head of the list. An ObjLink can be obtained by looping over a list using the above describe iterator method 3.

Reimplemented from TList.

Definition at line 49 of file TSortedList.h.

void TSortedList::AddFirst ( TObject *  obj )

inlinevirtual

Add object at the beginning of the list.

Reimplemented from TList.

Definition at line 41 of file TSortedList.h.

void TSortedList::AddFirst ( TObject *  obj, Option_t *  opt  )

inlinevirtual

Add object at the beginning of the list and also store option.

Storing an option is useful when one wants to change the behaviour of an object a little without having to create a complete new copy of the object. This feature is used, for example, by the Draw() method. It allows the same object to be drawn in different ways.

Reimplemented from TList.

Definition at line 42 of file TSortedList.h.

void TSortedList::AddLast ( TObject *  obj )

inlinevirtual

Add object at the end of the list.

Reimplemented from TList.

Definition at line 43 of file TSortedList.h.

void TSortedList::AddLast ( TObject *  obj, Option_t *  opt  )

inlinevirtual

Add object at the end of the list and also store option.

inlinevirtual

Reimplemented from TSeqCollection.

Definition at line 38 of file TSortedList.h.

void TSortedList::Sort ( Bool_t  order = kSortAscending )

inlinevirtual

Sort linked list.

Real sorting is done in private function DoSort(). The list can only be sorted when is contains objects of a sortable class.
