    • reset

      public void reset()
      Reset the buffer. Does not resize it back to a smaller size -- if it has ballooned it will stay large, though it will no longer have wasted space in it. If you wish to make the buffer a more manageable size, create a new DataPipe instead.

    • size

      public int size()
      Returns the total size of the buffer.

    • numWritten

      public int numWritten()
      Returns the number of elements written to the buffer so far (after the last reset()).

    • numRead

      public int numRead()
      Returns the number of elements read from the buffer so far (after the last reset()).

    • copy

      public static Object copy(Serializable obj) throws IOException, ClassNotFoundException
      A poor-man's clone for serializable but not cloneable objects: serializes an object to the pipe, then deserializes it.
      Throws:
      IOException
      ClassNotFoundException
