Class GridCacheOffheapSwapEntry<V>

java.lang.Object

org.apache.ignite.internal.processors.cache.GridCacheOffheapSwapEntry<V>

All Implemented Interfaces:

GridCacheSwapEntry<V>

public class GridCacheOffheapSwapEntry<V>
extends Object
implements GridCacheSwapEntry<V>

GridCacheSwapEntry over offheap pointer.

Offheap pointer points to marshalled GridCacheSwapEntryImpl instance, marshalled data:

• TTL
• Expire time
• GridCacheVersion or GridCacheVersionEx
• Value is byte array flag
• Value byte array (marshalled with portable or grid marshaller)
• Value classloader UUID
• Key classloader UUID
