-/**
- * TMemCache class
- *
- * TMemCache implements a cache application module based on {@link http://www.danga.com/memcached/ memcached}.
- *
- * TMemCache can be configured with the Host and Port properties, which
- * specify the host and port of the memcache server to be used.
- * By default, they take the value 'localhost' and 11211, respectively.
- * These properties must be set before {@link init} is invoked.
- *
- * The following basic cache operations are implemented:
- * - {@link get} : retrieve the value with a key (if any) from cache
- * - {@link set} : store the value with a key into cache
- * - {@link add} : store the value only if cache does not have this key
- * - {@link delete} : delete the value with the specified key from cache
- * - {@link flush} : delete all values from cache
- *
- * Each value is associated with an expiration time. The {@link get} operation
- * ensures that any expired value will not be returned. The expiration time can
- * be specified by the number of seconds (maximum 60*60*24*30)
- * or a UNIX timestamp. A expiration time 0 represents never expire.
- *
- * 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.
- *
- * Also note, there is no security measure to protected data in memcache.
- * All data in memcache can be accessed by any process running in the system.
- *
- * To use this module, the memcache PHP extension must be loaded.
- *
- * Some usage examples of TMemCache are as follows,
- * <code>
- * $cache=new TMemCache; // TMemCache may also be loaded as a Prado application module
- * $cache->init(null);
- * $cache->add('object',$object);
- * $object2=$cache->get('object');
- * </code>
- *
- * If loaded, TMemCache will register itself with {@link TApplication} as the
- * cache module. It can be accessed via {@link TApplication::getCache()}.
- *
- * TMemCache may be configured in application configuration file as follows
- * <code>
- * <module id="cache" class="System.Caching.TMemCache" Host="localhost" Port="11211" />
- * </code>
- * where {@link getHost Host} and {@link getPort Port} are configurable properties
- * of TMemCache.
