    fatalError(String message)
    Called to signal a fatal, non-recoverable error.
    static long
    getIsolateID()

    static void
    notifyLowMemoryPoint(boolean suggestFullGC)
    Notifies the runtime that the caller is at a point where the live set of objects is expected to just have decreased significantly and now is a good time for a partial or full collection.

  • Method Details

    • processReferences

      public static void processReferences()
      Enqueues pending References into their corresponding ReferenceQueues and executes pending cleaners. If automatic reference handling is enabled, this method is a no-op.

    • notifyLowMemoryPoint

      public static void notifyLowMemoryPoint(boolean suggestFullGC)
      Notifies the runtime that the caller is at a point where the live set of objects is expected to just have decreased significantly and now is a good time for a partial or full collection.
      Parameters:
      suggestFullGC - if a GC is performed, then suggests a full GC is done. This is true when the caller believes the heap occupancy is close to the minimal set of live objects for Graal (e.g. after a compilation).

    • getIsolateID

      public static long getIsolateID()
      Gets an identifier for the current isolate that is guaranteed to be unique for the first 2^64 - 1 isolates in the process.

    • fatalError

      public static void fatalError(String message)
      Called to signal a fatal, non-recoverable error. This method does not return or throw an exception but calls the HotSpot fatal crash routine that produces an hs-err crash log.
      Parameters:
      message - a description of the error condition
