<p>Event attribute containing a boolean. </p>
<p>This property allows the client to determine if all the possible gestures from the set of touches in this event have already been presented. When this value is true, the client will have received all the information needed to make a gesture accept and reject decision based on potentially overlapping gestures. An example is when both one and two touch gestures are subscribed on the same window with the same gesture classes and thresholds. When this property is true for one touch gesture events, the client can be sure there are no other touches unless a two touch gesture event has already been sent. Another example is when you subscribe for three touches Touch and four touches Drag. As soon as a third finger is detected a three touches Touch gesture will begin, but you cannot be sure a fourth finger isn't coming right after (that can eventually cause a four touches Drag) until this property is true. </p>
