   1 /**
   2  * A base class for all event recognizers in Sencha Touch.
   3  *
   4  * Sencha Touch, by default, includes various different {@link Ext.event.recognizer.Recognizer} subclasses to recognize
   5  * events happening in your application.
   6  *
   7  * ## Default recognizers
   8  *
   9  * * {@link Ext.event.recognizer.Tap}
  10  * * {@link Ext.event.recognizer.DoubleTap}
  11  * * {@link Ext.event.recognizer.LongPress}
  12  * * {@link Ext.event.recognizer.Drag}
  13  * * {@link Ext.event.recognizer.HorizontalSwipe}
  14  * * {@link Ext.event.recognizer.Pinch}
  15  * * {@link Ext.event.recognizer.Rotate}
  16  *
  17  * ## Additional recognizers
  18  *
  19  * * {@link Ext.event.recognizer.VerticalSwipe}
  20  *
  21  * If you want to create custom recognizers, or disable recognizers in your Sencha Touch application, please refer to the
  22  * documentation in {@link Ext#setup}.
