public void <B>resetStatistics</B>()</PRE>
<DL>
<DD>Resets the internal counters that are used to calculate the frame rate of the Compositor.<DD><DL>

</DD>
</DL>
<HR>

<A NAME="getStatistics()"><!-- --></A><H3>
getStatistics</H3>
<PRE>
public float <B>getStatistics</B>()</PRE>
<DL>
<DD>The compositor's frame rate is calculated by the number of times it is tickled from
 the time an application calls resetStatistics and is only valid if the rate of
 the Compositor's Timer is not zero. If this rate is zero this returns 0.
 Thus an application uses these calls like:
 <pre>
	myCompositor.resetStatistics();
	Thread.sleep (2000);	//sleep the stat's thread for 2 seconds to allow gathering of profile info
 	float fps = myCompositor.getStatistics();
 </pre>
 This call does not reset the internal counters, so consequent calls of getStatistics
 will return frames rendered over a longer period of time.<DD><DL>
