推 eieio:應該是別的地方有錯，補一下你怎麼放 new NNQE 和放進 queue 03/15 10:35
這是Comparator宣告
public static class NNQECompare implements Comparator<NNQE>{
public int compare(NNQE N1, NNQE N2){
if(N1.distance>N2.distance) return 1;
if(N1.distance<N2.distance) return -1;
return 0;
}
}
這是使用的地方
Priority.clear();
for(DataCache curB: Cache){
if(curB.ObjectCount != 0){
for(int j = 0; j < curB.ObjectCount ; j++){
t = new SpaceObject(curB.Items[j].x,curB.Items[j].y,curB.Items[j].id);
discompute=DisComputing(QItem, t);
if(discompute > RegionRadius)
continue;
else
Priority.add(new NNQE(t, discompute));
}
}
}
以下是NNQE的class
public class NNQE {
public double distance;
public SpaceObject element;
public NNQElement(SpaceObject O, double d)
{
element = O;
distance = d;
}
public double getdis(){
return distance;
}
}
