Class PairwiseSP.PathInFormat

java.lang.Object

eu.stratosphere.api.common.io.FileInputFormat<OT>

eu.stratosphere.api.common.io.DelimitedInputFormat<Record>

eu.stratosphere.api.java.record.io.DelimitedInputFormat

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

All Implemented Interfaces:

InputFormat<Record,FileInputSplit>, Serializable

Enclosing class:

PairwiseSP

public static class PairwiseSP.PathInFormat
extends DelimitedInputFormat

The PathInFormat reads paths consisting of a from-node a to-node, a length, and hop node list serialized as a string. All four elements of the path must be separated by the pipe character ('|') and may not contain any pipe characters itself. PathInFormat returns records with: - from-node at field position 0, - to-node at field position 1, - length at field position 2, - hop list at field position 3.
