        protected:

          TObject* fObject  pointer to object being represented by this entry

## Class Description

     TLegendEntry   Matthew.Adam.Dobbs@Cern.CH, September 1999
     Storage class for one entry of a TLegend

TLegendEntry(): TAttText(), TAttLine(), TAttFill(), TAttMarker()

     TLegendEntry do-nothing default constructor

TLegendEntry(TObject* obj, const char* label, Option_t* option ) :TAttText(12,0,1,0,0), TAttLine(1,1,1), TAttFill(0,0), TAttMarker(1,21,1)

    ___________________________________
     TLegendEntry normal constructor for one entry in a TLegend
       obj is the object this entry will represent. If obj has
       line/fill/marker attributes, then the TLegendEntry will display
       these attributes.
       label is the text that will describe the entry, it is displayed using
       TLatex, so may have a complex format.
       option may have values
        L draw line associated w/ TAttLine if obj inherits from TAttLine
        P draw polymarker assoc. w/ TAttMarker if obj inherits from TAttMarker
        F draw a box with fill associated w/ TAttFill if obj inherits TAttFill
       default is object = "LPF"

TLegendEntry( const TLegendEntry &entry ) : TObject(entry), TAttText(entry), TAttLine(entry), TAttFill(entry), TAttMarker(entry)

     TLegendEntry copy constructor

~TLegendEntry()

     TLegendEntry default destructor

void Copy( TObject &obj ) const

     copy this TLegendEntry into obj

void Print( Option_t *) const

     dump this TLegendEntry to cout

void SaveEntry( ofstream &out, const char* name )

     Save this TLegendEntry as C++ statements on output stream out
      to be used with the SaveAs .C option

void SetObject(TObject* obj )

     (re)set the obj pointed to by this entry

void SetObject( const char* objectName)

     (re)set the obj pointed to by this entry
