    - #### addMappingForServletNames

          void addMappingForServletNames(java.util.EnumSet<DispatcherType> dispatcherTypes,
                                       boolean isMatchAfter,
                                       java.lang.String... servletNames)

      Add a mapping for this filter to one or more named Servlets.
      Parameters:
        `dispatcherTypes` - The dispatch types to which this filter should apply
        `isMatchAfter` - Should this filter be applied after any mappings defined in the deployment descriptor (`true`) or before?
        `servletNames` - Requests mapped to these servlets will be processed by this filter
      Throws:
        `java.lang.IllegalArgumentException` - if the list of servlet names is empty or null
        `java.lang.IllegalStateException` - if the associated ServletContext has already been initialised

    - #### getServletNameMappings

          java.util.Collection<java.lang.String> getServletNameMappings()

      Returns:
        TODO

    - #### addMappingForUrlPatterns

          void addMappingForUrlPatterns(java.util.EnumSet<DispatcherType> dispatcherTypes,
