public class DataGravitatorInterceptor
extends BaseRpcInterceptor

The Data Gravitator interceptor intercepts cache misses and attempts t gravitate data from other parts of the cluster. Only used if Buddy Replication is enabled. Also, the interceptor only kicks in if an Option is passed in to force Data Gravitation for a specific invocation or if autoDataGravitation is set to true when configuring Buddy Replication. See the JBoss Cache User Guide for more details on configuration options. There is a section dedicated to Buddy Replication in the Replication chapter.
