Class DijkstraMoveCalculator.FieldInfoComparator

java.lang.Object
  civquest.units.DijkstraMoveCalculator.FieldInfoComparator

All Implemented Interfaces:

java.util.Comparator

Enclosing class:

DijkstraMoveCalculator

public class DijkstraMoveCalculator.FieldInfoComparator

extends java.lang.Object

implements java.util.Comparator

Comparator for comparing two FieldInfo-objects (needed for the heap used within the dijkstra-algorithm). info1 < info2 <=> (info1.turn < info2.turn) || (info1.turn == info2.turn && info1.time < info2.time <=> info1 describes an arrival that happens earlier than the arrival described in info2.
