Examples of org.infinispan.commands.control.RehashControlCommand

org.infinispan.commands.control.RehashControlCommand
A control command to coordinate rehashes that may occur when nodes join or leave a cluster, when DIST is used as a cache mode. This complex command coordinates the various phases of a rehash event when a joiner joins or a leaver leaves a cluster running in "distribution" mode.
It may break up into several commands in future. @author Manik Surtani @author Vladimir Blagojevic @since 4.0
