PHP Класс Prado\Caching\TEACache
*
* 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 eAccelerator PHP extension must be loaded and enabled
*
* Please note that as of v0.9.6, eAccelerator no longer supports data caching.
* This means if you still want to use this component, your eAccelerator should be of 0.9.5.x or lower version.
*
* Some usage examples of TEACache are as follows,
*
* $cache=new TEACache; // TEACache may also be loaded as a Prado application module
* $cache->init(null);
* $cache->add('object',$object);
* $object2=$cache->get('object');
*
*
* If loaded, TEACache will register itself with {@link TApplication} as the
* cache module. It can be accessed via {@link TApplication::getCache()}.
*
* TEACache may be configured in application configuration file as follows
*
