Class MonitorFactory

java.lang.Object
  net.sf.infrared.bootstrap.MonitorFactory

public class MonitorFactory

extends Object

Acts as the factory for creating MonitorFacade objects.

The aspects that need to advice a method call/execution for collecting monitoring data, gets the MonitorFacade instances from this factory. If no application is yet deployed in the server, this factory creates a DummyMonitorFacade which, as the name implies, does not do any monitoring. When an application is started, the MonitorFacadeImpl class is registered with the factory and the factory serves an instance of MonitorFacadeImpl on further requests for a MonitorFacade.
