Class Description

 TFileSet class is a class to convert the                             
      "native file system structure"                                  
 into an instance of the TDataSet class                               
    How to convert your home directory into the OO dataset            
  root [0] TString home = "$HOME";                                    
  root [1] TFileSet set(home);                                        
  root [2] TBrowser b("MyHome",&set);                                 
  root [3]"*");                                               

TFileSet() : TDataSet()

TFileSet(const TString &dirname,const Char_t *setname,Bool_t expand, Int_t maxDepth) : TDataSet()
 Creates TFileSet
 Convert the "opearting system" file system tree into the memory resided TFileSet

  dirname  - the name of the "native file system" directory
             to convert into TFileSet
  setname  - the name of this TFileSet (it is the "base name"
                                 of the "dirname" by default)
  expand   - flag whether the "dirname" must be "expanded
             (kTRUE by default)
  maxDeep  - the max number of the levels of the directory to read in
             (=10 by default)
  Note: If the "dirname" points to non-existent object, for examoe it is dead-link
  ----  the object is marked as "Zombie" and this flag is propagated upwards


Bool_t IsEmpty() const

Long_t HasData() const
 This implementation is done in the TDataSet::Purge() method in mind
 Since this method returns non-zero for files the last are NOT "purged"
 by TDataSet::Purge()

Bool_t IsFolder() const
 If the title of this TFileSet is "file" it is NOT folder
 see: TFileSet(TString &dirname,const Char_t *setname,Bool_t expand)
