org.gridgain.internal.table.nearcache.NearCacheValue<V>

public class NearCacheValue<V>
extends Object

Near Cache value. We need this class for 2 main reasons: 1. To distinguish between null and missing values in the table. For this purpose we have the exists flag; 2. To be able to store missing and null values in Caffeine, as you can not put null values in it.
