 -/**
 - * 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>
