class TDSetElement: public TNamed


TDSet

This class implements a data set to be used for PROOF processing.
The TDSet defines the class of which objects will be processed,
the directory in the file where the objects of that type can be
found and the list of files to be processed. The files can be
specified as logical file names (LFN's) or as physical file names
(PFN's). In case of LFN's the resolution to PFN's will be done
according to the currently active GRID interface.
Examples:
TDSet treeset("TTree", "AOD");
treeset.Add("lfn:/alien.cern.ch/alice/prod2002/file1");

treeset.AddFriend(friendset);

or

TDSet objset("MyEvent", "*", "/events");
objset.Add("root://cms.cern.ch/user/prod2002/hprod_1.root");

objset.Add(set2003);

Validity of file names will only be checked at processing time
(typically on the PROOF master server), not at creation time.

Function documentation

TDSetElement()

 Default constructor

TDSetElement(const char* file, const char* objname = 0, const char* dir = 0, Long64_t first = 0, Long64_t num = -1, const char* msd = 0, const char* dataset = 0)

 Create a TDSet element.

TDSetElement(const TDSetElement& elem)

 copy constructor

~TDSetElement()

 Clean up the element.

Int_t MergeElement(TDSetElement* elem)

 Check if 'elem' is overlapping or subsequent and, if the case, return
 a merged element.
 Returns:
     1    if the elements are overlapping
     0    if the elements are subsequent
    -1    if the elements are neither overlapping nor subsequent

TFileInfo * GetFileInfo(const char* type = "TTree")

 Return the content of this element in the form of a TFileInfo

const char * GetDirectory() const

 Return directory where to look for object.

void Print(Option_t* options = "") const

 Print a TDSetElement. When option="a" print full data.

void Validate(Bool_t isTree)

 Validate by opening the file.

void Validate(TDSetElement* elem)

 Validate by checking against another element.

Int_t Compare(const TObject* obj) const

Compare elements by filename (and the fFirst).

void AddFriend(TDSetElement* friendElement, const char* alias)

 Add friend TDSetElement to this set. The friend element will be copied to this object.

void DeleteFriends()

 Deletes the list of friends and all the friends on the list.

Long64_t GetEntries(Bool_t istree = kTRUE, Bool_t openfile = kTRUE)

 Returns number of entries in tree or objects in file.
 If not yet defined and 'openfile' is TRUE, get the number from the file
 (may considerably slow down the application).
 Returns -1 in case of error.

Int_t Lookup(Bool_t force = kFALSE)

 Resolve end-point URL for this element
 Return 0 on success and -1 otherwise

void SetEntryList(TObject* aList, Long64_t first = -1, Long64_t num = -1)

 Set entry (or event) list for this element

void AddAssocObj(TObject* assocobj)

 Add an associated object to the list

TObject * GetAssocObj(Long64_t i, Bool_t isentry = kFALSE)

 Get i-th associated object.
 If 'isentry' fFirst is subtracted, so that i == fFirst returns the first
 object in the list.
 If there are not enough elements in the list, the element i%list_size is
 returned (if the list has only one element this only one element is always
 returned.
 This method is used when packet processing consist in processing the objects
 in the associated object list.

void Streamer(TBuffer& b)

 Stream an object of class TDSetElement.
