| Defines events and listener interfaces for Tapestry. |
| |
| <p> |
| {@link org.apache.tapestry.event.ChangeObserver} |
| and |
| {@link org.apache.tapestry.event.ObservedChangeEvent} |
| are used to communicate changes in persistent properties |
| from pages and components to page recorders. |
| |
| <p> |
| The remaining interfaces |
| {@link org.apache.tapestry.event.PageDetachListener} and |
| {@link org.apache.tapestry.event.PageRenderListener} allow |
| objects to know about key lifecycle events regarding |
| a page. |
