  • Method Details

    • reset

      public static void reset()
      Re-initializes all static state, in particular, the URLChecker service registry

    • register

      public static void register(URLChecker checker)
      Dynamically register a new URLChecker. The operation removes all instances of the same classes already present in the registry, if multiple instances are needed, one can use subclasses (eventually, anonymous inner classes) so that the instances are not sharing exactly the same class.

    • deregister

      public static void deregister(URLChecker checker)
      Dynamically removes a new URLChecker, that might have been registered using the register(URLChecker) method.

    • getEnabledURLCheckers

      public static List<URLChecker> getEnabledURLCheckers()
      Returns:
      enabled list of org.geotools.data.ows.URLChecker implementations

    • confirm

      public static void confirm(URL url) throws URLCheckerException
      Confirm the URL against all enabled URLChecker
      Parameters:
      url - to confirm using all available URLCheckers
      Throws:
      URLCheckerException - if the URL is not allowed for use

    • confirm

      public static void confirm(URI uri) throws URLCheckerException
      Confirms URI against all enabled URLChecker
      Parameters:
      uri - to evaluate using all available URLCheckers
      Throws:
      URLCheckerException - if the URI is not allowed for use

    • normalize

      public static String normalize(String location)
      Normalize location removing current directory . and parent directory .. names.

      Normalization uses URI.normalize() for URI and URL locations. Path locations are normalized using Path.normalize().

      This normalization method forces empty hostname file:///path representation to provide a consistent location to check. RFC 8089 supports both empty hostname file:///path and file:/path no hostname as references to the same absolute path.

      Keep in mind that file paths are standardized to / on linux and \\ on windows.

      Parameters:
      location - String(URI/URI/path)
      Returns:
      normalized location, removing redundant . and .. path names if required

    • confirm

      public static void confirm(String location) throws URLCheckerException
      Confirm the location against all enabled URLChecker.
      Parameters:
      location - String(URI/URI/path) to be normalized and evaluated using all available URLCheckers
      Throws:
      URLCheckerException - if the location is not allowed for use
