| <p>The classes in this package enable "scenes & transitions" functionality for |
| view hiearchies.</p> |
| |
| <p>A <b>Scene</b> is an encapsulation of the state of a view hierarchy, |
| including the views in that hierarchy and the various values (layout-related |
| and otherwise) that those views have. A scene can be defined by a layout hierarchy |
| directly or by code which sets up the scene dynamically as it is entered.</p> |
| |
| <p>A <b>Transition</b> is a mechanism to automatically animate changes that occur |
| when a new scene is entered. Some transition capabilities are automatic. That |
| is, entering a scene may cause animations to run which fade out views that |
| go away, changeBounds and resize existing views that change, and fade in views that |
| become visible. There are additional transitions that can animate other |
| attributes, such as color changes, and which can optionally be specified |
| to take place during particular scene changes. Finally, developers can |
| define their own Transition subclasses which monitor particular property |
| changes and which run custom animations when those properties change values.</p> |
| |
| <p><b>TransitionManager</b> is used to specify custom transitions for particular |
| scene changes, and to cause scene changes with specific transitions to |
| take place.</p> |
