@interface GMSMutablePath : GMSPath

GMSMutablePath is a dynamic (resizable) array of CLLocationCoordinate2D. All coordinates must be valid. GMSMutablePath is the mutable counterpart to the immutable GMSPath.

• Adds coord at the end of the path.

  Declaration

  Swift

  func add(_ coord: CLLocationCoordinate2D)

  Objective-C

  - (void)addCoordinate:(CLLocationCoordinate2D)coord;

• Adds a new CLLocationCoordinate2D instance with the given lat/lng.

  Declaration

  Swift

  func addLatitude(_ latitude: CLLocationDegrees, longitude: CLLocationDegrees)

  Objective-C

  - (void)addLatitude:(CLLocationDegrees)latitude
            longitude:(CLLocationDegrees)longitude;

• Declaration

  Swift

  func insert(_ coord: CLLocationCoordinate2D, at index: UInt)

  Objective-C

  - (void)insertCoordinate:(CLLocationCoordinate2D)coord
                   atIndex:(NSUInteger)index;

• Replace the coordinate at index with coord. If index is after the end, grows the array with an undefined coordinate.

  Declaration

  Swift

  func replaceCoordinate(at index: UInt, with coord: CLLocationCoordinate2D)

  Objective-C

  - (void)replaceCoordinateAtIndex:(NSUInteger)index
                    withCoordinate:(CLLocationCoordinate2D)coord;

• Remove entry at index.

  If index < count decrements size. If index >= count this is a silent no-op.

  Declaration

  Swift

  func removeCoordinate(at index: UInt)

  Objective-C

  - (void)removeCoordinateAtIndex:(NSUInteger)index;

• Removes the last coordinate of the path.

  If the array is non-empty decrements size. If the array is empty, this is a silent no-op.

  Declaration

  Swift

  func removeLastCoordinate()

  Objective-C

  - (void)removeLastCoordinate;

• Removes all coordinates in this path.

  Declaration

  Swift

  func removeAllCoordinates()

  Objective-C

  - (void)removeAllCoordinates;
