PHP Класс Prado\Caching\TXCache

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,


$cache=new TXCache;  // TXCache may also be loaded as a Prado application module
$cache->init(null);
$cache->add('object',$object);
$object2=$cache->get('object');

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
