java.lang.Object

eu.stratosphere.api.common.functions.AbstractFunction

eu.stratosphere.api.java.record.functions.CoGroupFunction

eu.stratosphere.example.java.record.shortestpaths.PairwiseSP.FindShortestPath

All Implemented Interfaces:

Function, GenericCoGrouper<Record,Record,Record>, Serializable

Enclosing class:

PairwiseSP

public static class PairwiseSP.FindShortestPath
extends CoGroupFunction
implements Serializable

Gets two lists of paths as input and emits for each included from-node/to-node combination the shortest path(s). If for a combination more than one shortest path exists, all shortest paths are emitted.
