# RadarGeofence

> Represents a geofence with geometry, metadata, and operating hours.

`RadarGeofence` represents a geofence. Learn more about [Geofences](https://radar.com/documentation/geofences).

## Properties

<ResponseField name="_id" type="String" required>
  The Radar ID of the geofence.
</ResponseField>

<ResponseField name="__description" type="String" required>
  The description of the geofence. Not to be confused with the `NSObject` `description` property.
</ResponseField>

<ResponseField name="tag" type="String">
  The tag of the geofence.
</ResponseField>

<ResponseField name="externalId" type="String">
  The external ID of the geofence.
</ResponseField>

<ResponseField name="metadata" type="NSDictionary">
  The optional set of custom key-value pairs for the geofence.
</ResponseField>

<ResponseField name="geometry" type="RadarGeofenceGeometry" required>
  The geometry of the geofence, which can be cast to either `RadarCircleGeometry` or `RadarPolygonGeometry`.

  <Expandable title="RadarCircleGeometry">
    <ResponseField name="center" type="RadarCoordinate" required>
      The center of the circle geofence.
    </ResponseField>

    <ResponseField name="radius" type="double" required>
      The radius of the circle geofence in meters.
    </ResponseField>
  </Expandable>

  <Expandable title="RadarPolygonGeometry">
    <ResponseField name="_coordinates" type="Array<RadarCoordinate>">
      The geometry of the polygon geofence. A closed ring of coordinates.
    </ResponseField>

    <ResponseField name="center" type="RadarCoordinate" required>
      The calculated centroid of the polygon geofence.
    </ResponseField>

    <ResponseField name="radius" type="double" required>
      The calculated radius of the polygon geofence in meters.
    </ResponseField>
  </Expandable>

  <Expandable title="RadarCoordinate">
    <ResponseField name="coordinate" type="CLLocationCoordinate2D" required>
      The coordinate.
    </ResponseField>
  </Expandable>
</ResponseField>

<ResponseField name="operatingHours" type="RadarOperatingHours">
  The optional operating hours for the geofence.

  <Expandable title="properties">
    <ResponseField name="hours" type="NSDictionary<NSString *, NSArray<NSArray<NSString *> *> *>" required>
      A dictionary mapping day names to arrays of time ranges. Each time range is an array of two strings representing the start and end times.
    </ResponseField>
  </Expandable>
</ResponseField>

## Methods

### arrayForGeofences

```objective-c theme={null}
+ (NSArray<NSDictionary *> *_Nullable)arrayForGeofences:(NSArray<RadarGeofence *> *_Nullable)geofences;
```

Converts an array of `RadarGeofence` objects to an array of dictionaries.

### dictionaryValue

```objective-c theme={null}
- (NSDictionary *_Nonnull)dictionaryValue;
```

Returns the dictionary representation of the geofence.

## Example

```swift theme={null}
let geofence: RadarGeofence = event.geofence
let geofenceId = geofence._id
let geofenceDescription = geofence.__description
let geofenceTag = geofence.tag
let geofenceExternalId = geofence.externalId
let geofenceMetadata = geofence.metadata

if let circleGeometry = geofence.geometry as? RadarCircleGeometry {
    let center = circleGeometry.center
    let radius = circleGeometry.radius
} else if let polygonGeometry = geofence.geometry as? RadarPolygonGeometry {
    let center = polygonGeometry.center
    let radius = polygonGeometry.radius
    let coordinates = polygonGeometry._coordinates
}
```

```objective-c theme={null}
RadarGeofence *geofence = event.geofence;
NSString *geofenceId = geofence._id;
NSString *geofenceDescription = geofence.__description;
NSString *geofenceTag = geofence.tag;
NSString *geofenceExternalId = geofence.externalId;
NSDictionary *geofenceMetadata = geofence.metadata;

if ([geofence.geometry isKindOfClass:[RadarCircleGeometry class]]) {
    RadarCircleGeometry *circleGeometry = (RadarCircleGeometry *)geofence.geometry;
    RadarCoordinate *center = circleGeometry.center;
    double radius = circleGeometry.radius;
} else if ([geofence.geometry isKindOfClass:[RadarPolygonGeometry class]]) {
    RadarPolygonGeometry *polygonGeometry = (RadarPolygonGeometry *)geofence.geometry;
    RadarCoordinate *center = polygonGeometry.center;
    double radius = polygonGeometry.radius;
    NSArray<RadarCoordinate *> *coordinates = polygonGeometry._coordinates;
}
```
