public synchronized int getOriginalBytes(long offset, byte[] b, int off, int length)

	}
Tries to get length (original) bytes from the files starting at the given offset and put them 
into the given byte array at the specified offset into the byte array.  May return
fewer bytes if the requested length is beyond the end of the file bytes.

@param offset the offset into the files bytes to start.
@param b the byte array to populate.
@param off the offset into the byte array.
@param length the number of bytes to get.
@return the number of bytes actually populated.
@throws IOException if there is an error reading from the database
@throws IndexOutOfBoundsException if the destination offset and length would exceed the
size of the buffer b.
