Class ZkContainer

java.lang.Object

org.apache.solr.core.ZkContainer

public class ZkContainer
extends Object

Used by CoreContainer to hold ZooKeeper / SolrCloud info, especially ZkController. Mainly it does some ZK initialization, and ensures a loading core registers in ZK. Even when in standalone mode, perhaps surprisingly, an instance of this class exists. If getZkController() returns null then we're in standalone mode.
