-/**
- * Smarty Cache Handler Base for Key/Value Storage Implementations
- * This class implements the functionality required to use simple key/value stores
- * for hierarchical cache groups. key/value stores like memcache or APC do not support
- * wildcards in keys, therefore a cache group cannot be cleared like "a|*" - which
- * is no problem to filesystem and RDBMS implementations.
- * This implementation is based on the concept of invalidation. While one specific cache
- * can be identified and cleared, any range of caches cannot be identified. For this reason
- * each level of the cache group hierarchy can have its own value in the store. These values
- * are nothing but microtimes, telling us when a particular cache group was cleared for the
- * last time. These keys are evaluated for every cache read to determine if the cache has
- * been invalidated since it was created and should hence be treated as inexistent.
- * Although deep hierarchies are possible, they are not recommended. Try to keep your
- * cache groups as shallow as possible. Anything up 3-5 parents should be ok. So
- * »a|b|c« is a good depth where »a|b|c|d|e|f|g|h|i|j|k« isn't. Try to join correlating
- * cache groups: if your cache groups look somewhat like »a|b|$page|$items|$whatever«
- * consider using »a|b|c|$page-$items-$whatever« instead.
