Tracing Server Resource Change Events
Using the Server API, you can trace the change of server resources caused by the following actions: Create, Open, Save, Delete, Change Permission, Change Property and Copy. To do this, you need to implement the listener interface ResourceNotifyTrigger and then add the implemented class to RptServer by calling RptServer.getResourceActionNotifier().addNotifyTrigger(ResourceNotifyTrigger trigger) in order to get action notification.
The following shows a resource action trigger. You need to implement the interface. When a resource action happens, the beforeAction() and afterAction() methods are called.
public interface ResourceNotifyTrigger {
public void beforeAction(ResourceNotifyInfo info)
public void afterAction(ResourceNotifyInfo info);Logi JReport Server sends the resource information right before and after the change defined in the ResourceNotifyInfo object happens:
public interface ResourceNotifyInfo {
public boolean isNode();
public PathInfo getResourceInfo();
public String getResourcePath();
public SERVER_ACTION_TYPE getActionType();
public SERVER_ACTION_SOURCE getActionSource();
public RptServer getServer();
public JUser getUserInfo();
public HttpSession getHttpSession();
}Below shows how to specify the action type and action source:
- The types of server actions performed on the resources can be specified as follows:
public static enum SERVER_ACTION_TYPE { Create, Open, Save, Delete, ChangePermission, ChangeProperty, Copy } - The types of server action sources indicating where the actions are sent can be specified as follows:
public static enum SERVER_ACTION_SOURCE { Designer, ServerConsole, ServerAdmin, API_RMI, API_Local, API_URL, Studio_Page, Studio_Web, Dashboard, VisualAnalysis }
