23 <p class="p3">An <b>EventStreamPlayer</b> is used by Event based Patterns. <span class="Apple-converted-space"> </span></p>
24 <p class="p3">You do not explictly create an EventStreamPlayers, they are created for you</p>
25 <p class="p3">when you call Pattern-play.</p>
26 <p class="p2"><br></p>
27 <p class="p3">The <b>EventStreamPlayer</b> holds a stream which returns a series of Events, and a protoEvent. At each call to next, it copies the protoEvent, passes that to the stream, and calls <b>play</b> on the <b>Event</b> returned.</p>
