Interface IEndPointSnitch

All Known Implementing Classes:

AbstractEndpointSnitch, DatacenterEndPointSnitch, EndPointSnitch

public interface IEndPointSnitch

This interface helps determine location of node in the data center relative to another node. Give a node A and another node B it can tell if A and B are on the same rack or in the same data center. Not all methods will be germate to all implementations. Throw UnsupportedOperation as necessary.

Method Summary

java.util.List<java.net.InetAddress>	getSortedListByProximity(java.net.InetAddress address, java.util.Collection<java.net.InetAddress> unsortedAddress) returns a new List sorted by proximity to the given endpoint
java.util.List<java.net.InetAddress>	sortByProximity(java.net.InetAddress address, java.util.List<java.net.InetAddress> addresses) This method will sort the List according to the proximity of the given address.
