Class AbstractEjbTimingAspect

java.lang.Object

net.jperf.aop.AgnosticTimingAspect

net.jperf.aop.AbstractEjbTimingAspect

Direct Known Subclasses:

EjbTimingAspect, EjbTimingAspect, EjbTimingAspect, EjbTimingAspect

public abstract class AbstractEjbTimingAspect
extends AgnosticTimingAspect

This is the base class for TimingAspects that use the EJB interceptor framework. Subclasses just need to implement the newStopWatch(java.lang.String, java.lang.String) method to use their logging framework of choice (e.g. log4j or java.logging) to persist the StopWatch log message.

                                                 String levelName)

Subclasses should implement this method to return a LoggingStopWatch that should be used to time the wrapped code block.

Parameters:

loggerName - The name of the logger to use for persisting StopWatch messages.

levelName - The level at which the message should be logged.

Returns:

The new LoggingStopWatch.
