1<html> 2<body> 3<p>The classes in this package enable "scenes & transitions" functionality for 4view hiearchies.</p> 5 6<p>A <b>Scene</b> is an encapsulation of the state of a view hierarchy, 7including the views in that hierarchy and the various values (layout-related 8and otherwise) that those views have. A scene can be defined by a layout hierarchy 9directly or by code which sets up the scene dynamically as it is entered.</p> 10 11<p>A <b>Transition</b> is a mechanism to automatically animate changes that occur 12when a new scene is entered. Some transition capabilities are automatic. That 13is, entering a scene may cause animations to run which fade out views that 14go away, changeBounds and resize existing views that change, and fade in views that 15become visible. There are additional transitions that can animate other 16attributes, such as color changes, and which can optionally be specified 17to take place during particular scene changes. Finally, developers can 18define their own Transition subclasses which monitor particular property 19changes and which run custom animations when those properties change values.</p> 20 21<p><b>TransitionManager</b> is used to specify custom transitions for particular 22scene changes, and to cause scene changes with specific transitions to 23take place.</p> 24 25</body> 26</html> 27
