    • Method Detail

      • getDigester

        Digester getDigester()
        Returns:
        the Digester instance with which this Rules instance is associated.
      • setDigester

        void setDigester​(Digester digester)
        Set the Digester instance with which this Rules instance is associated.
        Parameters:
        digester - The newly associated Digester instance
      • add

        void add​(String pattern,
                 Rule rule)
        Register a new Rule instance matching the specified pattern.
        Parameters:
        pattern - Nesting pattern to be matched for this Rule
        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:
        namespaceURI - Namespace URI for which to select matching rules, or null to match regardless of namespace URI
        pattern - Nesting pattern to be matched
        Returns:
        a rules list
      • rules

        List<Rule> rules()
        Return a List of all registered Rule instances, or a zero-length List if there are no registered Rule instances. If more than one Rule instance has been registered, they must be returned in the order originally registered through the add() method.
        Returns:
        a rules list
