# 八、围栏

# （一）围栏与围栏事件

门户系统允许将地图要素设置为电子围栏。根据设置围栏触发类型（进入触发/离开触发），当由成员进入/离开电子围栏时，就会生成围栏事件。

# （二）设置围栏

FenceInfo fenceInfo = markerFeature.fenceInfo;
fenceInfo.enable = true;//启用围栏
fenceInfo.radius = 10;//围栏半径
fenceInfo.triggerType = FenceTriggerType.In;//围栏触发类型

//markerFeature的更新需由其所属的集合对象markerSet来操作
markerSet.updateMarker(markerFeature, new CsCallback() {
    @Override
    public void onSuccess(Object object) {
        //更新markerFeature信息成功（设置围栏成功）
    }

    @Override
    public void onFailure(ErrorMessage errorMessage) {
        int errorCode = errorMessage.getCode();//错误码
        String errorMsg = errorMessage.getMessage();//错误信息
    }
});

# （三）围栏事件[FenceEvent]

# 1、获取围栏事件

Organization organization = Cellsys.organization;//初始化成功之后，可随时获取组织对象。
organization.queryFenceEvent(new CsCallback<QueryResult<FenceEvent>>() {
    @Override
    public void onSuccess(QueryResult<FenceEvent> object) {
        List<FenceEvent> fenceEvents = object.data;
    }

    @Override
    public void onFailure(ErrorMessage errorMessage) {
        int errorCode = errorMessage.getCode();//错误码
        String errorMsg = errorMessage.getMessage();//错误信息
    }
});

# 2、围栏事件信息

//围栏触发类型(进入/离开）
FenceTriggerType fenceTriggerType = fenceEvent.triggerType;
//围栏触发人
fenceEvent.triggerMember.getName();//触发人名称
Location location = fenceEvent.locationOnTriggered;//触发人定位信息
/*查询具体的触发人信息*/
fenceEvent.queryTriggerDetail(new CsCallback<QueryResult<MemberFeature>>() {
    @Override
    public void onSuccess(QueryResult<MemberFeature> object) {
        MemberFeature memberFeature = object.data.get(0);
    }

    @Override
    public void onFailure(ErrorMessage errorMessage) {
        int errorCode = errorMessage.getCode();//错误码
        String errorMsg = errorMessage.getMessage();//错误信息
    }
});

//围栏信息
fenceEvent.mapFeatureOfFence.getName();//围栏名称
Geometry geometry = fenceEvent.fenceGeometry;//围栏坐标信息
/*查询具体的围栏信息*/
fenceEvent.queryMapFeatureDeatil(new CsCallback<QueryResult<MapFeature>>() {
    @Override
    public void onSuccess(QueryResult<MapFeature> object) {
        MapFeature mapFeature = object.data.get(0);
        if (mapFeature instanceof MarkerFeature) {
            MarkerFeature markerFeature = (MarkerFeature) mapFeature;
        } else if (mapFeature instanceof LineFeature) {
            LineFeature lineFeature = (LineFeature) mapFeature;
        } else if (mapFeature instanceof AreaFeature) {
            AreaFeature areaFeature = (AreaFeature) mapFeature;
        }
    }

    @Override
    public void onFailure(ErrorMessage errorMessage) {
        int errorCode = errorMessage.getCode();//错误码
        String errorMsg = errorMessage.getMessage();//错误信息
    }
});

# 3、创建围栏事件

初始化成功后，可通过Cellsys的organization对象创建围栏事件。代码示例如下：

MemberFeature memberFeature = getMember();//触发人
MarkerFeature fence = getMarker();//触发围栏,可以是标记、路线、区域
double lat = 23.12366;//纬度
double lng = 113.521352;//经度
MapPoint mapPoint = new MapPoint(lat, lng);//点坐标
long timeStamp = TimeUtil.getTime();//获取时间戳
DateTime dateTime = new DateTime(timeStamp);//定位时间
Location location = new Location(mapPoint, dateTime);//触发时的定位信息
Cellsys.organization.createFenceEvent(memberFeature, location, fence, new CsCallback<FenceEvent>() {
    @Override
    public void onSuccess(FenceEvent object) {
        /*成功*/
    }
   
    @Override
    public void onFailure(ErrorMessage errorMessage) {
        /*失败*/
        int code = errorMessage.getCode();//错误码
        String errMsg = errorMessage.getMessage();//错误信息
    }
});
