◆ GetLast()

Int_t TSeqCollection::GetLast ( ) const
virtual

Returns index of last object in collection.

Returns -1 when no objects in collection.

Reimplemented in TListOfFunctions, TRefArray, TObjArray, and TListOfEnumsWithLock.

Definition at line 47 of file TSeqCollection.cxx.

◆ IndexOf()

Int_t TSeqCollection::IndexOf ( const TObject obj) const
virtual

Return index of object in collection.

Returns -1 when object not found. Uses member IsEqual() to find object.

Reimplemented in TObjArray, TRefArray, TListOfFunctions, TOrdCollection, and TListOfEnumsWithLock.

◆ LastIndex()

Int_t TSeqCollection::LastIndex ( ) const
inline

Definition at line 55 of file TSeqCollection.h.

◆ Merge()

Long64_t TSeqCollection::Merge ( TCollection list)

Merge this collection with all collections coming in the input list.

The input list must contain other collections of objects compatible with the ones in this collection and ordered in the same manner. For example, if this collection contains a TH1 object and a tree, all collections in the input list have to contain a histogram and a tree. In case the list contains collections, the objects in the input lists must also be collections with the same structure and number of objects. If some objects inside the collection are instances of a class that do not have a Merge function (like TObjString), rather than merging, a copy of each instance (via a call to Clone) is appended to the output.

Example

this list
____________ ---------------------|
| A (TH1F) | __________ | L1 (TSeqCollection)|- [A1, B1(C1,D1,E1)]
| B (TList)|-| C (TTree)| | L1 (TSeqCollection)|- [A2, B2(C2,D2,E2)]
|__________| | D (TH1F) | | ... |- [...]

Int_t TSeqCollection::ObjCompare ( TObject a,
TObject b 
)
static

Compare to objects in the collection. Use member Compare() of object a.

◆ QSort() [1/3]

void TSeqCollection::QSort ( TObject **  a,
Int_t  first,
Int_t  last 
)
static

Sort array of TObject pointers using a quicksort algorithm.

The algorithm used is a non stable sort (i.e. already sorted elements might switch/change places). Uses ObjCompare() to compare objects.

Definition at line 70 of file TSeqCollection.cxx.

Int_t  nBs,
TObject ***  b,
Int_t  first,
Int_t  last 
)
static

Sort array a of TObject pointers using a quicksort algorithm.

Arrays b will be sorted just like a (a determines the sort). Argument nBs is the number of TObject** arrays in b. The algorithm used is a non stable sort (i.e. already sorted elements might switch/change places). Uses ObjCompare() to compare objects.
