- org.apache.avalon.framework.component.Component, org.apache.avalon.framework.configuration.Configurable, org.apache.avalon.framework.logger.Loggable, Monitor, org.apache.avalon.framework.thread.ThreadSafe
- public final class PassiveMonitor
- extends org.apache.avalon.framework.logger.AbstractLoggable
- implements Monitor, org.apache.avalon.framework.component.Component, org.apache.avalon.framework.thread.ThreadSafe, org.apache.avalon.framework.configuration.Configurable
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 ComponentManager. It defaults to checking every 1 minute. The configuration
looks like this:
<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>
</monitor>
