      public static org.aspectj.org.eclipse.jdt.internal.compiler.util.JrtFileSystem getJrtSystem(File image, String release)
      Parameter:
      image - the path to the root of the JRE whose libraries we are interested in.
      release - --release version

    • getJarFileSystem

      public static FileSystem getJarFileSystem(Path path) throws IOException
      Convenient method to get access to the given archive as a FileSystem.

      Note: if the file system for given archive was already created before, the method will reuse existing file system, otherwise a new FileSystem object will be created.

      The caller should not close returned FileSystem as it might be shared with others.

      Parameter:
      path - absolute file path to a jar archive
      Gibt zurück:
      never null
      Löst aus:
      IOException

    • reset

      public static void reset()
      TEST ONLY (use when changing the "modules.to.load" property).

    • 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.
      Parameter:
      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.
      Löst aus:
      IOException
