<p>This class represents a piece of data stored by the grouping framework within a grouping result, which can
subsequently be sent back along with the original request to navigate across a large result set. It is an opaque
data object that is not intended to be human readable.</p>

<p>To render a continuation within a result set, you simply need to call {@link #toString()}.</p>
