    • Method Detail

      • lookupClass

        public static Class<? extends CharFilterFactory> lookupClass​(String name)
        looks up a charfilter class by name from context classpath
      • availableCharFilters

        public static Set<String> availableCharFilters()
        returns a list of all available charfilter names
      • findSPIName

        public static String findSPIName​(Class<? extends CharFilterFactory> serviceClass)
        looks up a SPI name for the specified char filter factory
      • reloadCharFilters

        public static void reloadCharFilters​(ClassLoader classloader)
        Reloads the factory list from the given ClassLoader. Changes to the factories are visible after the method ends, all iterators (availableCharFilters(),...) stay consistent.

        NOTE: Only new factories are added, existing ones are never removed or replaced.

        This method is expensive and should only be called for discovery of new factories on the given classpath/classloader!

      • create

        public abstract Reader create​(Reader input)
        Wraps the given Reader with a CharFilter.
      • normalize

        public Reader normalize​(Reader input)
        Normalize the specified input Reader While the default implementation returns input unchanged, char filters that should be applied at normalization time can delegate to create method.
