All Implemented Interfaces:

public class PassiveMonitor

extends PassiveMonitor

implements LogEnabled, Configurable, ThreadSafe

The PassiveMonitor is used to passively check a set of resources to see if they have changed. It will be implemented as a Component, that can be retrieved from the ComponentLocator. It defaults to checking every 1 minute. The configuration looks like this:

   <passive-monitor>
     <init-resources>
       <-- This entry can be repeated for every resource you want to register immediately -->

       <resource key="file:./myfile.html" class="org.apache.avalon.excalibur.monitor.FileMonitor"/>
     </init-resources>
   </pasive-monitor>
