Examples of CacheViewControlCommand

org.infinispan.commands.control.CacheViewControlCommand
A control command to coordinate the installation of cache views between the members of the cluster. The coordinator will receive REQUEST_JOIN and REQUEST_LEAVE commands from the nodes starting or stopping a cache. It then sends PREPARE_VIEW to all the nodes in the cluster. If all nodes return a successful response, the coordinator then sends a COMMIT_VIEW command to everyone. If there is a failure on one of the nodes, the coordinator cancels the view with a ROLLBACK_VIEW command. @author Dan Berindei @since 5.1
