Examples of org.jboss.cache.commands.read.GravitateDataCommand

org.jboss.cache.commands.read.GravitateDataCommand
Used with buddy replication's {@link org.jboss.cache.interceptors.DataGravitatorInterceptor}.
This is the equivalent of the old MethodCallDefinitions.dataGravitationMethod method call from 2.1.x.
