<p class="phpdocumentor-summary">CacheItemInterface defines an interface for interacting with objects inside a cache.</p>
<section class="phpdocumentor-description"><p>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.</p>
<p>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.</p>
<p>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.</p>
