AMXMBeanLogger

public final class AMXMBeanLogger extends com.sun.appserv.management.base.AMXLoggerBase
The logger class for all MBean loggers.

When constructing an MBean Logger, we derive its name from the ObjectName of the MBean. The Javadoc for the logger class states: Logger names can be arbitrary strings...". This convention is followed in spirit; the logger name for an MBean is followed by forming a dotted string which consists of a common prefix followed by the hierarchy of parents of the form or :, depending on whether the MBean has a name or not.

Fields Summary
private final ObjectName
mObjectName
private static final String
TYPE_NAME_DELIM
public static final String
OBJECT_NAME_KEY
Override so that we can include the ObjectName in every LogRecord.
Constructors Summary
private AMXMBeanLogger(ObjectName objectName)

		this( objectName, null );
		throw new IllegalArgumentException();	// don't use this routine
private AMXMBeanLogger(ObjectName objectName, String resourceBundleName)

		super( createLoggerName( objectName ), resourceBundleName );
		
		mObjectName	= objectName;
		throw new IllegalArgumentException();	// don't use this routine
