Class NodeRank

java.lang.Object

org.corfudb.protocols.wireprotocol.failuredetector.NodeRank

All Implemented Interfaces:

Comparable<NodeRank>, ICorfuPayload<NodeRank>

public class NodeRank
extends Object
implements ICorfuPayload<NodeRank>, Comparable<NodeRank>

The rank of the node in a graph. Sorting nodes according to rank used to search for decision makers, failed nodes and so on. Sorting according to: - Descending order of number of connections - Ascending order of a node name (alphabetically)
