Examples of Topology

avrora.sim.radio.freespace.Topology
handles node positions. @author Olaf Landsiedel
base.drawable.Topology
com.alu.e3.topology.model.Topology
Maintains a list of instances
org.apache.cassandra.locator.TokenMetadata.Topology
org.apache.geronimo.datastore.impl.remote.messaging.Topology
Abstracts the topology of a set of nodes.
Nodes are related by paths, which are physical connections, having a weight. Based on this knowledge, Topology is able to derive the shortest path - the one having the lowest weight - between two nodes.
This class is intended to be sent to a multicast group when a topology event happens. @version $Revision: 1.3 $ $Date: 2004/03/18 12:14:05 $
org.apache.hadoop.gateway.topology.Topology
org.apache.stratos.messaging.domain.topology.Topology
Defines a topology of serviceMap in Stratos.
