             Summary: Log: cache result of log.isTraceEnabled()
                 Key: JGRP-2130
                 URL: https://issues.jboss.org/browse/JGRP-2130
             Project: JGroups
          Issue Type: Enhancement
            Reporter: Bela Ban
            Assignee: Bela Ban
            Priority: Minor
             Fix For: 4.0


e.g. 
{noformat}
boolean trace=log.isTraceEnabled();
loop {
   if(trace) ...
}
{noformat}

Unfortunately, {{isTraceEnabled()}} is not free in most scenarios, so the cost of invoking this method should be amortized over multiple calls.

I don't want to cache this at a global level, or else we wouldn't be able to change the log level at runtime...
