	 * interpretation by the caller.

	 * Note this method may be called on initial moving or copying of a
	 * resource, or when a move or copy is undone or redone. Therefore, this
	 * method should check conditions that can change over the life of the
	 * operation, such as whether the file to moved or copied exists, and
	 * whether the target location is still valid. One-time static checks should
	 * typically be done by the caller so that the user is not continually
	 * prompted or warned about conditions that were acceptable at the time of
	 * original execution and do not change over time.

	 * @return the status indicating the projected outcome of moving or copying
	 *         the resources.
