Class Horizontal.JobComparator

java.lang.Object

edu.isi.pegasus.planner.cluster.Horizontal.JobComparator

All Implemented Interfaces:

java.util.Comparator

Enclosing class:

Horizontal

private static class Horizontal.JobComparator
extends java.lang.Object
implements java.util.Comparator

A job comparator, that allows me to compare jobs according to the transformation names. It is applied to group jobs in a particular partition, according to the underlying transformation that is referred.

This comparator is not consistent with the Job.equals(Object) method. Hence, should not be used in sorted sets or Maps.
