JMXMonitorBase

public class JMXMonitorBase extends com.sun.enterprise.management.support.AMXImplBase
Implementation of javax.management.monitor.StringMonitor which is an AMX.

Fields Summary
final Monitor
mMonitor
Constructors Summary
protected JMXMonitorBase(Monitor mon)
Because we want our implementation to be an AMX, we will extend appropriately, but this means that we must delegate javax.management.StringMonitor functionality to an instance of that class.

		mMonitor	= mon;
