30Abtract interface representing a 'licensee' of a hardware buffer copy.
31<p>
32remarks Often it's useful to have temporary buffers which are used for working but are not necessarily needed permanently. However, creating and destroying buffers is expensive, so we need a way to share these working areas, especially those based on existing fixed buffers. This class represents a licensee of one of those temporary buffers, and must be implemented by any user of a temporary buffer if they wish to be notified when the license is expired.
