All Implemented Interfaces:

ISOValidator

public class ISOMsgFieldValidatingPackager
extends ISOMsgFieldPackager
implements ISOValidator

THIS CLASS SHOWS THAT IsoMsgFieldValidator IS NOT NECESSARY. IF WE MODIFY CURRENT PACKAGER ISOMsgFieldPackager. IF IT IMPLEMENTS ISOValidator INTERFACE, AND ADD validate(ISOComponent c) METHOD LIKE HERE. IN TesterValidatingPackager FILE WE COULD CHANGE FIELD 48 VALIDATOR TO THAT NEW ISOMsgFieldValidator. SEE COMMENTED LINE.
