All Implemented Interfaces:

Serializable, CacheAffinityFunction

public class GridExternalAffinityFunction
extends Object
implements CacheAffinityFunction

Mock affinity implementation that ensures constant key-to-node mapping based on GridCacheModuloAffinity The partition selection is as follows: 0 maps to partition 1 and any other value maps to partition 1.
