setCoalesce</H3>
<PRE>
public void <B>setCoalesce</B>(boolean&nbsp;flag)</PRE>
<DL>
<DD>Sets whether the Timer coalesces multiple pending ActionEvent firings.
 A busy application may not be able
 to keep up with a Timer's message generation, causing multiple
 <b>actionPerformed()</b> message sends to be queued.  When processed,
 the application sends these messages one after the other, causing the
 Timer's listeners to receive a sequence of <b>actionPerformed()</b>
 messages with no delay between them. Coalescing avoids this situation
 by reducing multiple pending messages to a single message send. Timers
 coalesce their message sends by default.<DD><DL>
