Class GridCacheVersionManager

java.lang.Object

org.apache.ignite.internal.processors.cache.GridCacheSharedManagerAdapter

org.apache.ignite.internal.processors.cache.version.GridCacheVersionManager

All Implemented Interfaces:

GridCacheSharedManager

public class GridCacheVersionManager
extends GridCacheSharedManagerAdapter

Makes sure that cache lock order values come in proper sequence.

NOTE: this class should not make use of any cache specific structures, like, for example GridCacheContext, as it may be reused between different caches.
