public final Class XPropertyCache

extends Object
Class Inheritance
Imports
java.util.*
Implements abstract X window property caching mechanism. The caching is performed using storeCache method, the cached data can be retrieved using getCacheEntry method.

Note

current caching is disabled because of the big variate of uncovered access to properties/changes of properties. Once the access to properties is rewritten using general mechanisms, caching will be enabled.
