Bool_t fIsTree true if type is a TTree (or TTree derived)
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.
TDSetElement(const char *file, const char *objname, const char *dir,
Long64_t first, Long64_t num,
const char *msd)
Create a TDSet element.
TDSetElement(const TDSetElement& elem) : TObject()
copy constructor
~TDSetElement()
Clean up the element.
const char* GetObjName() const
Return object name.
const char* GetDirectory() const
Return directory where to look for object.
void Print(Option_t *opt) 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.
