Cluster Topology
The interface net.sf.ehcache.cluster.CacheCluster provides methods for obtaining topology information for a Terracotta cluster. The following methods are available:
*String getScheme()
Returns a scheme name for the cluster information. Currently TERRACOTTA is the only scheme supported. The scheme name is used by CacheManager.getCluster() to return cluster information.
*Collection<ClusterNode> getNodes()
Returns information on all the nodes in the cluster, including ID, hostname, and IP address.
*boolean addTopologyListener(ClusterTopologyListener listener)
Adds a cluster-events listener. Returns true if the listener is already active.
*boolean removeTopologyListener(ClusterTopologyListener)
Removes a cluster-events listener. Returns true if the listener is already inactive.
The interface net.sf.ehcache.cluster.ClusterNode provides methods for obtaining information on specific cluster nodes.
public interface ClusterNode {
