19 // This class helps passing information from the TFileMerger to //
20 // the objects being merged. //
21 // //
22 // It provides access to the output directory pointer (fOutputDirectory)//
23 // to whether or not this is the first time Merge is being called in the//
24 // serie (for example for TTree, the first time we also need to Clone //
25 // the object on which Merge is called), and provides for a User Data //
26 // object to be passed along to each of the calls to Merge. //
27 // The fUserData object is owned by the TFileMergeInfo and will be //
28 // deleted when the TFileMerger moves on to the next set of objects. //
