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

All Implemented Interfaces:

Function, GenericJoiner<Record,Record,Record>, Serializable

Enclosing class:

PairwiseSP

public static class PairwiseSP.ConcatPaths
extends JoinFunction
implements Serializable

Concatenates two paths where the from-node of the first path and the to-node of the second path are the same. The second input path becomes the first part and the first input path the second part of the output path. The length of the output path is the sum of both input paths. The output path's hops list is built from both path's hops lists and the common node.
