我在地图上有一组点.我正在尝试创建集群.除了距离之外,我还在考虑每个集群的最大成本(作为另一个参数).
请找到以下代码段.
private void assignCluster(List<Cluster> finalClusters, List<Node> clusterNodes, int maxCostLimit) {
double max = Double.MAX_VALUE;
double min = max;
int clusterIndex = 0;
double distance = 0.0;

min = max;
for (int i = 0; i < finalClusters.size(); i++) {
Cluster cluster = finalClusters.get(i);
distance = Point.getDistanceBetweenPoints(node.getPoint(), cluster.getPoint());
if (distance < min && (cluster.getTotalCost() + node.getCost()) <= maxCostLimit) {
min = distance;

我需要检查访问者的数组中是否已存在某些card_id.我该怎么办?我尝试了一个循环但是没有用,因为当我得到一个新的data.card_id并且访问者数组中已经有多个条目时它可能不匹配.
我的代码:
$scope.$on("addMultiVisitor", function(evt, data) {
$scope.newVisit.visitors.length + 1;
$scope.newVisit.visitors.push({
"access_route_id": "",
"card_id": data.id,
"identity_id": data.identity.id,
"company_id": data.company.id,
"company_name": data.company.name,
"firstname": data.identity.given_names,
"lastname": data.identity.surname,
"birthdate": new Date(data.identity.birthdate)
});
window.scrollTo(0, document.body.scrollHeight);
$scope.$apply();
