TList Class Reference

A doubly linked list.

All classes inheriting from TObject can be inserted in a TList. Before being inserted into the list the object pointer is wrapped in a TObjLink object which contains, besides the object pointer also a previous and next pointer.

There are several ways to iterate over a TList; in order of preference, if not forced by other constraints: 0. (Preferred way) Using the C++ range-based for or begin() / end():

for(const auto&& obj: *GetListOfPrimitives())
obj->Write();
  1. Using the R__FOR_EACH macro:
    GetListOfPrimitives()->R__FOR_EACH(TObject,Paint)(option);
  2. Using the TList iterator TListIter (via the wrapper class TIter):
    TIter next(GetListOfPrimitives());
    while ((TObject *obj = next()))
    obj->Draw(next.GetOption());
  3. Using the TList iterator TListIter and std::for_each algorithm:
    // A function object, which will be applied to each element
    // of the given range.
    struct STestFunctor {
    bool operator()(TObject *aObj) {
    ...
    return true;
    }
    }
    ...
    ...
    TIter iter(mylist);
    for_each( iter.Begin(), TIter::End(), STestFunctor() );
  4. Using the TObjLink list entries (that wrap the TObject*):
    TObjLink *lnk = GetListOfPrimitives()->FirstLink();
    while (lnk) {
    lnk->GetObject()->Draw(lnk->GetOption());
    lnk = lnk->Next();
    }
  5. Using the TList's After() and Before() member functions:
    TFree *idcur = this;
    while (idcur) {
    ...
    ...
    idcur = (TFree*)GetListOfFree()->After(idcur);
    }
    Methods 2, 3 and 4 can also easily iterate backwards using either a backward TIter (using argument kIterBackward) or by using LastLink() and lnk->Prev() or by using the Before() member.

void TList::AddFirst ( TObject obj,
Option_t opt

virtual

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.

Obj is found using the object's IsEqual() method. Returns 0 if obj is first in list.

Implements TSeqCollection.

Reimplemented in TListOfFunctions, TViewPubDataMembers, TViewPubFunctions, and TListOfEnumsWithLock.

Definition at line 348 of file TList.cxx.

void TList::Clear ( Option_t option = "")
virtual

Remove all objects from the list.

Does not delete the objects unless the TList is the owner (set via SetOwner()) and option "nodelete" is not set. If option="nodelete" then don't delete any heap objects that were marked with the kCanDelete bit, otherwise these objects will be deleted (this option is used by THashTable::Clear()).

Implements TCollection.

virtual

Remove all objects from the list AND delete all heap based objects.

Find an object in this list using the object's IsEqual() member function.

Requires a sequential scan till the object has been found. Returns 0 if object is not found. This method overrides the generic FindObject() of TCollection for efficiency reasons.

Reimplemented from TCollection.

Reimplemented in TListOfFunctions, THashList, TListOfEnumsWithLock, TViewPubDataMembers, and TViewPubFunctions.

TObject * TList::First ( ) const
virtual

Return the first object in the list. Returns 0 when list is empty.

Bool_t TList::LnkCompare ( TObjLink l1,

Compares the objects stored in the TObjLink objects.

Depending on the flag IsAscending() the function returns true if the object in l1 <= l2 (ascending) or l2 <= l1 (descending).
