public static class UIDefaults.ProxyLazyValue extends Object implements UIDefaults.LazyValue
LazyValue
which can be
used to delay loading of the Class for the instance to be created.
It also avoids creation of an anonymous inner class for the
LazyValue
subclass. Both of these improve performance at the time that a
a Look and Feel is loaded, at the cost of a slight performance
reduction the first time createValue is called
(since Reflection APIs are used).| Constructor and Description |
