Class TokenMetadata.Topology

java.lang.Object
  org.apache.cassandra.locator.TokenMetadata.Topology

Enclosing class:

TokenMetadata

public static class TokenMetadata.Topology
extends java.lang.Object

Tracks the assignment of racks and endpoints in each datacenter for all the "normal" endpoints in this TokenMetadata. This allows faster calculation of endpoints in NetworkTopologyStrategy.

Constructor Summary

protected	TokenMetadata.Topology()
protected	TokenMetadata.Topology(TokenMetadata.Topology other) construct deep-copy of other

Method Summary

protected void	addEndpoint(java.net.InetAddress ep) Stores current DC/rack assignment for ep
protected void	clear()
com.google.common.collect.Multimap<java.lang.String,java.net.InetAddress>	getDatacenterEndpoints()
java.util.Map<java.lang.String,com.google.common.collect.Multimap<java.lang.String,java.net.InetAddress>>	getDatacenterRacks()
protected void	removeEndpoint(java.net.InetAddress ep) Removes current DC/rack assignment for ep
