InstanceSupport

• java.lang.Object

Fields Summary
private org.apache.catalina.InstanceListener[]	listeners The set of registered InstanceListeners for event notifications.
private org.apache.catalina.Wrapper	wrapper The source component for instance events that we will fire.

Constructors Summary
public InstanceSupport(org.apache.catalina.Wrapper wrapper) Construct a new InstanceSupport object associated with the specified Instance component. param wrapper The component that will be the source of events that we fire super(); this.wrapper = wrapper;

Methods Summary
public void	addInstanceListener(org.apache.catalina.InstanceListener listener) Add a lifecycle event listener to this component. param listener The listener to add synchronized (listeners) { InstanceListener results[] = new InstanceListener[listeners.length + 1]; for (int i = 0; i < listeners.length; i++) results[i] = listeners[i]; results[listeners.length] = listener; listeners = results; }
public void	fireInstanceEvent(java.lang.String type, javax.servlet.Servlet servlet, javax.servlet.ServletRequest request, javax.servlet.ServletResponse response) Notify all lifecycle event listeners that a particular event has occurred for this Container. The default implementation performs this notification synchronously using the calling thread. param type Event type param servlet The relevant Servlet for this event param request The servlet request we are processing param response The servlet response we are processing if (listeners.length == 0) return; InstanceEvent event = new InstanceEvent(wrapper, servlet, type, request, response); InstanceListener interested[] = listeners; for (int i = 0; i < interested.length; i++) interested[i].instanceEvent(event);
public void	fireInstanceEvent(java.lang.String type, javax.servlet.Servlet servlet, javax.servlet.ServletRequest request, javax.servlet.ServletResponse response, java.lang.Throwable exception) Notify all lifecycle event listeners that a particular event has occurred for this Container. The default implementation performs this notification synchronously using the calling thread. param type Event type param servlet The relevant Servlet for this event param request The servlet request we are processing param response The servlet response we are processing param exception Exception that occurred if (listeners.length == 0) return; InstanceEvent event = new InstanceEvent(wrapper, servlet, type, request, response, exception); InstanceListener interested[] = listeners; for (int i = 0; i < interested.length; i++) interested[i].instanceEvent(event);
public void	fireInstanceEvent(java.lang.String type, javax.servlet.Filter filter) Notify all lifecycle event listeners that a particular event has occurred for this Container. The default implementation performs this notification synchronously using the calling thread. param type Event type param filter The relevant Filter for this event if (listeners.length == 0) return; InstanceEvent event = new InstanceEvent(wrapper, filter, type); InstanceListener interested[] = listeners; for (int i = 0; i < interested.length; i++) interested[i].instanceEvent(event);
public void	fireInstanceEvent(java.lang.String type, javax.servlet.Filter filter, java.lang.Throwable exception) Notify all lifecycle event listeners that a particular event has occurred for this Container. The default implementation performs this notification synchronously using the calling thread. param type Event type param filter The relevant Filter for this event param exception Exception that occurred if (listeners.length == 0) return; InstanceEvent event = new InstanceEvent(wrapper, filter, type, exception); InstanceListener interested[] = listeners; for (int i = 0; i < interested.length; i++) interested[i].instanceEvent(event);
public void	fireInstanceEvent(java.lang.String type, javax.servlet.Filter filter, javax.servlet.ServletRequest request, javax.servlet.ServletResponse response) Notify all lifecycle event listeners that a particular event has occurred for this Container. The default implementation performs this notification synchronously using the calling thread. param type Event type param filter The relevant Filter for this event param request The servlet request we are processing param response The servlet response we are processing if (listeners.length == 0) return; InstanceEvent event = new InstanceEvent(wrapper, filter, type, request, response); InstanceListener interested[] = listeners; for (int i = 0; i < interested.length; i++) interested[i].instanceEvent(event);
public void	fireInstanceEvent(java.lang.String type, javax.servlet.Filter filter, javax.servlet.ServletRequest request, javax.servlet.ServletResponse response, java.lang.Throwable exception) Notify all lifecycle event listeners that a particular event has occurred for this Container. The default implementation performs this notification synchronously using the calling thread. param type Event type param filter The relevant Filter for this event param request The servlet request we are processing param response The servlet response we are processing param exception Exception that occurred if (listeners.length == 0) return; InstanceEvent event = new InstanceEvent(wrapper, filter, type, request, response, exception); InstanceListener interested[] = listeners; for (int i = 0; i < interested.length; i++) interested[i].instanceEvent(event);

public org.apache.catalina.Wrapper	getWrapper() Return the Wrapper with which we are associated. // ------------------------------------------------------------- Properties return (this.wrapper);
public void	removeInstanceListener(org.apache.catalina.InstanceListener listener) Remove a lifecycle event listener from this component. param listener The listener to remove synchronized (listeners) { int n = -1; for (int i = 0; i < listeners.length; i++) { if (listeners[i] == listener) { n = i; break; } } if (n < 0) return; InstanceListener results[] = new InstanceListener[listeners.length - 1]; int j = 0; for (int i = 0; i < listeners.length; i++) { if (i != n) results[j++] = listeners[i]; } listeners = results; }
