All Implemented Interfaces:

java.lang.Runnable, Monitor, org.apache.avalon.framework.activity.Startable, org.apache.avalon.framework.component.Component, org.apache.avalon.framework.configuration.Configurable, org.apache.avalon.framework.logger.LogEnabled, org.apache.avalon.framework.thread.ThreadSafe

public class ActiveMonitor
extends ActiveMonitor
implements org.apache.avalon.framework.logger.LogEnabled, org.apache.avalon.framework.configuration.Configurable, org.apache.avalon.framework.activity.Startable, org.apache.avalon.framework.thread.ThreadSafe

The ActiveMonitor is used to actively 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:

   <active-monitor>
     <thread priority="5" frequency="60000"/>
     <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.FileResource"/>
     </init-resources>
   </active-monitor>
