+/**
+ * CacheItemInterface defines an interface for interacting with objects inside a cache.
+ *
+ * Each Item object MUST be associated with a specific key, which can be set
+ * according to the implementing system and is typically passed by the
+ * Cache\CacheItemPoolInterface object.
+ *
+ * The Cache\CacheItemInterface object encapsulates the storage and retrieval of
+ * cache items. Each Cache\CacheItemInterface is generated by a
+ * Cache\CacheItemPoolInterface object, which is responsible for any required
+ * setup as well as associating the object with a unique Key.
+ * Cache\CacheItemInterface objects MUST be able to store and retrieve any type
+ * of PHP value defined in the Data section of the specification.
+ *
+ * Calling Libraries MUST NOT instantiate Item objects themselves. They may only
+ * be requested from a Pool object via the getItem() method.  Calling Libraries
+ * SHOULD NOT assume that an Item created by one Implementing Library is
+ * compatible with a Pool from another Implementing Library.
