      • getDigester

        Digester getDigester()

        void setDigester​(Digester digester)
        Set the Digester instance with which this Rules instance is associated.
        Parameters:

      • add

        void add​(String pattern,
         Rule rule)
        Register a new Rule instance matching the specified pattern.
        Parameters:

        rule - Rule instance to be registered

      • clear

        void clear()
        Clear all existing Rule instance registrations.

      • match

        List<Rule> match​(String namespaceURI,
                 String pattern)
        Return a List of all registered Rule instances that match the specified nesting pattern, or a zero-length List if there are no matches. If more than one Rule instance matches, they must be returned in the order originally registered through the add() method.
        Parameters:
