    AsciiString         from TCollection

-- raises

is

    -- Specific methods -------------------------------------------------------

    Data (me : mutable; aDF : Data from TDF);

    Data (me)
    returns Data from TDF;
    
    OpenRoot(me)
    	returns AsciiString from TCollection;
	---Purpose: Returns a string composed with the sub-label
	--          entries of <myDF>.

    OpenLabel(me; aLab : Label from TDF)
    	returns AsciiString from TCollection;
	---Purpose: Returns a string composed with the sub-label
	--          entries of <aLab>.

    OpenAttributeList(me : mutable;
    	    	      aLab : Label from TDF)
    	returns AsciiString from TCollection;
	---Purpose: Returns a string composed with the attribute index
	--          (found in <myAttMap>) of <aLab>.

    OpenAttribute(me : mutable;
    	    	  anIndex : Integer from Standard = 0)
    	returns AsciiString from TCollection;
	---Purpose: Returns a string composed with the list of
	--          referenced attribute index of the attribute
	--          <anIndex>. For exemple, it is usefull for
	--          TDataStd_Group. It uses a mecanism based on a

    Information(me)
    	returns AsciiString from TCollection;
	---Purpose: Returns information about <me> to be displayed in
	--          information window.

    Information(me; aLab : Label from TDF)
    	returns AsciiString from TCollection;
	---Purpose: Returns information about <aLab> to be displayed
	--          in information window.

    Information(me; anIndex : Integer from Standard = 0)
    	returns AsciiString from TCollection;
	---Purpose: Returns information about attribute <anIndex> to
	--          be displayed in information window.
