TDSet Class Reference

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.

◆ TDSet() [1/4]

iterator on fSrvMaps

Definition at line 704 of file TDSet.cxx.

◆ TDSet() [3/4]

TDSet::TDSet ( const char *  name,
const char *  objname = "*",
const char *  dir = "/",
const char *  type = 0 
)

Create a named TDSet object.

The "type" defines the class of which objects will be processed (default 'TTree'). The optional "objname" argument specifies the name of the objects of the specified class. If the "objname" is not given the behaviour depends on the 'type': for 'TTree' the first TTree is analyzed; for other types, all objects of the class found in the specified directory are processed. The "dir" argument specifies in which directory the objects are to be found, the top level directory ("/") is the default. Directories can be specified using wildcards, e.g. "*" or "/*" means to look in all top level directories, "/dir/*" in all directories under "/dir", and "/*/*" to look in all directories two levels deep. For backward compatibility the type can also be passed via 'name', in which case 'type' is ignored.

Definition at line 741 of file TDSet.cxx.

◆ TDSet() [4/4]

TDSet::TDSet ( const TChain chain,
Bool_t  withfriends = kTRUE 
)

Create a named TDSet object from existing TChain 'chain'.

If 'withfriends' is kTRUE add also friends. This constructor substituted the static methods TChain::MakeTDSet removing any residual dependence of 'tree' on 'proof'.

Add files passed as list of TFileInfo, TUrl or TObjString objects .

If TFileInfo, the first entry and the number of entries are also filled. The argument 'meta' can be used to specify one of the subsets in the file as described in the metadata of TFileInfo. By default the first one is taken. If 'availableOnly' is true only files available ('staged' and non corrupted) are taken: those not satisfying this requirement are added to 'badlist', if the latter is defined. By default availableOnly is false.
