-/**
- * TCacheDependency class.
- *
- * TCacheDependency is the base class implementing {@link ICacheDependency} interface.
- * Descendant classes must implement {@link getHasChanged()} to provide
- * actual dependency checking logic.
- *
- * The property value of {@link getHasChanged HasChanged} tells whether
- * the dependency is changed or not.
- *
- * You may disable the dependency checking by setting {@link setEnabled Enabled}
- * to false.
- *
- * Note, since the dependency objects often need to be serialized so that
- * they can persist across requests, you may need to implement __sleep() and
- * __wakeup() if the dependency objects contain resource handles which are
- * not serializable.
- *
- * Currently, the following dependency classes are provided in the PRADO release:
- * - {@link TFileCacheDependency}: checks whether a file is changed or not
- * - {@link TDirectoryCacheDependency}: checks whether a directory is changed or not
- * - {@link TGlobalStateCacheDependency}: checks whether a global state is changed or not
- * - {@link TChainedCacheDependency}: checks whether any of a list of dependencies is changed or not
- *
