public interface ServerCache

Represents part of the "L2" server side cache.

This is used to cache beans or query results (bean collections).

There are 2 ServerCache's for each bean type. One is used as the 'bean cache' which holds beans of a given type. The other is the 'query cache' holding query results for a given type.
