- * TXCache class
- *
- * TXCache implements a cache application module based on {@link http://xcache.lighttpd.net/ xcache}.
- *
- * By definition, cache does not ensure the existence of a value
- * even if it never expires. Cache is not meant to be an persistent storage.
- *
- * To use this module, the xcache PHP extension must be loaded and configured in the php.ini.
- *
- * Some usage examples of TXCache are as follows,
- * <code>
- * $cache=new TXCache; // TXCache may also be loaded as a Prado application module
- * $cache->init(null);
- * $cache->add('object',$object);
- * $object2=$cache->get('object');
- * </code>
- *
- * If loaded, TXCache will register itself with {@link TApplication} as the
- * cache module. It can be accessed via {@link TApplication::getCache()}.
- *
- * TXCache may be configured in application configuration file as follows
- * <code>
- * <module id="cache" class="System.Caching.TXCache" />
- * </code>
