    • walkModuleImage

      public static void walkModuleImage(File image, JRTUtil.JrtFileVisitor<Path> visitor, int notify) throws IOException
      Given the path of a modular image file, this method walks the archive content and notifies the supplied visitor about packages and files visited. The file system contains the following top level directories: /modules/$MODULE/$PATH /packages/$PACKAGE/$MODULE The latter provides quick look up of the module that contains a particular package. However, this method only notifies its clients of the entries within the modules (former) sub-directory. Clients can decide which notifications they want to receive. See NOTIFY_ALL, NOTIFY_FILES, NOTIFY_PACKAGES and NOTIFY_MODULES.
      Parameters:
      image - a java.io.File handle to the JRT image.
      visitor - an instance of JrtFileVisitor to be notified of the entries in the JRT image.
      notify - flag indicating the notifications the client is interested in.
      Throws:
      IOException

      public static byte[] safeReadBytes(Path path) throws IOException

      Parameters:
      path -
      Returns:
      bytes or null
      Throws:
