<body>

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.
