InstanceEvent

• java.lang.Object
  • java.util.EventObject

Fields Summary
public static final String	BEFORE_INIT_EVENT The event indicating that the init() method is about to be called for this instance.
public static final String	AFTER_INIT_EVENT The event indicating that the init() method has returned.
public static final String	BEFORE_SERVICE_EVENT The event indicating that the service() method is about to be called on a servlet. The servlet property contains the servlet being called, and the request and response properties contain the current request and response being processed.
public static final String	AFTER_SERVICE_EVENT The event indicating that the service() method has returned. The servlet property contains the servlet that was called, and the request and response properties contain the current request and response being processed.
public static final String	BEFORE_DESTROY_EVENT The event indicating that the destroy method is about to be called for this instance.
public static final String	AFTER_DESTROY_EVENT The event indicating that the destroy() method has returned.
public static final String	BEFORE_DISPATCH_EVENT The event indicating that the service() method of a servlet accessed via a request dispatcher is about to be called. The servlet property contains a reference to the dispatched-to servlet instance, and the request and response properties contain the current request and response being processed. The wrapper property will contain a reference to the dispatched-to Wrapper.
public static final String	AFTER_DISPATCH_EVENT The event indicating that the service() method of a servlet accessed via a request dispatcher has returned. The servlet property contains a reference to the dispatched-to servlet instance, and the request and response properties contain the current request and response being processed. The wrapper property will contain a reference to the dispatched-to Wrapper.
public static final String	BEFORE_FILTER_EVENT The event indicating that the doFilter() method of a Filter is about to be called. The filter property contains a reference to the relevant filter instance, and the request and response properties contain the current request and response being processed.
public static final String	AFTER_FILTER_EVENT The event indicating that the doFilter() method of a Filter has returned. The filter property contains a reference to the relevant filter instance, and the request and response properties contain the current request and response being processed.
private Throwable	exception The exception that was thrown during the processing being reported by this event (AFTER_INIT_EVENT, AFTER_SERVICE_EVENT, AFTER_DESTROY_EVENT, AFTER_DISPATCH_EVENT, and AFTER_FILTER_EVENT only).
private Filter	filter The Filter instance for which this event occurred (BEFORE_FILTER_EVENT and AFTER_FILTER_EVENT only).
private ServletRequest	request The servlet request being processed (BEFORE_FILTER_EVENT, AFTER_FILTER_EVENT, BEFORE_SERVICE_EVENT, and AFTER_SERVICE_EVENT).
private ServletResponse	response The servlet response being processed (BEFORE_FILTER_EVENT, AFTER_FILTER_EVENT, BEFORE_SERVICE_EVENT, and AFTER_SERVICE_EVENT).
private Servlet	servlet The Servlet instance for which this event occurred (not present on BEFORE_FILTER_EVENT or AFTER_FILTER_EVENT events).
private String	type The event type this instance represents.
private Wrapper	wrapper The Wrapper managing the servlet instance for which this event occurred.
