Class \Prado\Caching\TAPCCache
TAPCCache implements a cache application module based on APCu.
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 APCu PHP extension must be loaded and set in the php.ini file.
Some usage examples of TAPCCache are as follows,
$cache=new TAPCCache; // TAPCCache may also be loaded as a Prado application module
$cache->init(null);
$cache->add('object',$object);
$object2=$cache->get('object');
If loaded, TAPCCache will register itself with TApplication as the cache module. It can be accessed via TApplication::getCache().
TAPCCache may be configured in application configuration file as follows
<module id="cache" class="Prado\Caching\TAPCCache" />
