It is specific -- of each sub-class of Signature. For a Null Handle, it should -- provide "" -- It can work with the model which contains the entity Label (me) returns AsciiString; ---Purpose : The label of a Signature uses its name as follow : -- "Signature : " Matches (me; ent : Transient; model : InterfaceModel; text : AsciiString; exact : Boolean) returns Boolean is virtual; ---Purpose : Tells if the value for in matches a text, with -- a criterium . -- The default definition calls MatchValue -- Can be redefined MatchValue (myclass; val : CString; text : AsciiString; exact : Boolean) returns Boolean; ---Purpose : Default procedure to tell if a value matches a text -- with a criterium . = True requires equality, -- else only contained (no reg-exp) IntValue (myclass; val : Integer) returns CString; ---Purpose : This procedure converts an Integer to a CString -- It is a convenient way when the value of a signature has the -- form of a simple integer value -- The value is to be used immediately (one buffer only, no copy) fields thecasi : Integer[3]; thecasl : HSequenceOfAsciiString; thename : AsciiString is protected; end Signature;
