| Interfaces | |
|---|---|
| ChangeObserver | May observe changes in an object's properties. |
| PageAttachListener | Listener interface notified when a page is attached to the current request. |
| PageBeginRenderListener | Event listener for determining when a page is about to start rendering. |
| PageDetachListener | An interface for objects that want to know when the end of the request cycle occurs, so that any resources that should be limited to just one request cycle can be released. |
| PageEndRenderListener | Counterpart to PageBeginRenderListener , for the (typically less-interesting) end of page render event. |
| PageRenderListener | An object that listens to page events. |
| PageValidateListener | An interface for objects that want to take part in the validation of the page. |
| ReportStatusListener | Implemented by (typically) a HiveMind service implementation, and registerred with the ReportStatusHub so that the service can report its status (in terms of properties and values). |
| ResetEventListener | Listener interface for objects interested in a Tapestry reset event. |
| Classes | |
|---|---|
| ObservedChangeEvent | Event which describes a change to a particular IComponent . |
| PageEvent | Encapsulates information related to the page listener interfaces. |
| ReportStatusEvent | Event object used by ReportStatusListener ; the event implements DescriptionReceiver ; classes (typically, HiveMind service implementations) that implement the listener interface will "describe" themselves to the event. |
ChangeObserver and ObservedChangeEvent are used to communicate changes in persistent properties from pages and components to page recorders.
The remaining interfaces PageDetachListener and PageRenderListener allow objects to know about key lifecycle events regarding a page.
