## org.apache.cassandra.locator
Class SimpleSnitch

    java.lang.Object
      org.apache.cassandra.locator.AbstractEndpointSnitch
          org.apache.cassandra.locator.SimpleSnitch

All Implemented Interfaces:
  IEndpointSnitch

    public class SimpleSnitch

extends AbstractEndpointSnitch

A simple endpoint snitch implementation that treats Strategy order as proximity, allowing non-read-repaired reads to prefer a single endpoint, which improves cache locality.

Constructor Summary
`SimpleSnitch()`

Method Summary
`int` | `compareEndpoints(java.net.InetAddress target, java.net.InetAddress a1, java.net.InetAddress a2)` compares two endpoints in relation to the target endpoint, returning as Comparator.compare would
`java.lang.String` | `getDatacenter(java.net.InetAddress endpoint)` returns a String representing the datacenter this endpoint belongs to
`java.lang.String` | `getRack(java.net.InetAddress endpoint)` returns a String repesenting the rack this endpoint belongs to
`void` | `sortByProximity(java.net.InetAddress address, java.util.List<java.net.InetAddress> addresses)` Sorts the `List` of node addresses, in-place, by proximity to the given address

Methods inherited from class org.apache.cassandra.locator.AbstractEndpointSnitch
`getSortedListByProximity, gossiperStarting`

Methods inherited from class java.lang.Object
`clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait`
