Examples of org.geoserver.platform.resource.Resource.addListener()

org.geoserver.platform.resource.Resource.addListener()

Listen for changes to ResourceStore content.

Listeners can be configured to check for changes to individual files or directory contents.

styles: listener receives events for any change to the contents of the styles directory
user_projections/epsg.properties: listener notified for any change to the epsg.properties resource

Notification is course grained, often just based on change of last modified time stamp, as such they are issued after the change has been performed.

@param listener Listener to receive change notification

                    // remove this when wms works off style info
                    style.setName( info.getName() );
                    styleCache.put( info, style );
                    
                    final Resource styleResource = dataDir().style(info);
                    styleResource.addListener( new ResourceListener() {
                        @Override
                        public void changed(ResourceNotification notify) {
                            styleCache.remove(info);
                            styleResource.removeListener( this );
                        }
