-/**
- * 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.
