Data Members

    private:

       TString fFilename   ROOT filename
       TString fDirectory  Path to object
       TString fClassName  Class name or base class of the object
      TObject* fObject     Object pointer

 This class is responsible or reading and writing ROOT objects in   
 ROOT files. It can be used only with objects which are independent 
 of the TFile once they have been loaded by their streamer. It      
 means, for example, that a TTree object cannot be loaded in memory 
 using QSigExIO.                                                    
                                                                    

This function loads an object from a ROOT file which filename is filename.
The objectname argument can be a simple object name, if the object is
located in the root directory of the file, or it can be the path to the
object (ex: "mydir/myobject").

This function saves the object to the file and directory where it has been
read/saved the last time.

This function saves the object in directory directory of ROOT file which
filename is filename. If the second argument is not provided, the object
will be saved in the root directory of the file.

This function copies by value the content of object QSigExIO to this.

This function returns a pointer to the object.

This function resets the current object.

This function checks if the TObject which pointer is uptr belong to or is
derived from class classname.

 Stream an object of class QSigExIO.
