    • intern

      public static String intern(byte[] bytes)

    • internObject

      public static Object internObject(Object toIntern)
      A generic interning facility for heavyweight or frequently duplicated Objects that have a reasonable equals() implementation.

      Important: The objects should have a limited lifespan, the interning set used by this method is unmanaged, i.e. does not clean out old entries! Entries without strong references are still removed.

    • intern

      public static String intern(String toIntern)

    • intern

      public static char[] intern(char[] toIntern)

    • internBytes

      public static byte[] internBytes(byte[] toIntern)

    • internFile

      public static File internFile(File toIntern)
      This is based on File.hashCode() and File.equals(), which can return different values for different representations of the same paths. Thus internFile should be used with canonized Files exclusively

    • internURL

      public static URL internURL(URL toIntern)

    • sanitizeLight

      private static void sanitizeLight()

    • sanitize

      private static void sanitize(boolean scheduled)
