MapObjectManager

Extends: Hashable
public static func == (lhs: MapObjectManager, rhs: MapObjectManager) -> Bool

Returns a Boolean value indicating whether two values are equal.
This documentation comment was inherited from .

public convenience init(
    map: Map,
    layerId: String? = nil
)

Create IMapObjectManager.

Parameters
map
layerId
String?

ID of a layer with "Dynamic object" style type. Created objects will be stored in this layer so that you can define their order relative to other layers. If not set, objects are stored above other layers.

Methods
public func hash(into hasher: inout Hasher)

Hashes the essential components of this value by passing them to the given hasher.

Parameters
hasher
Hasher

Hasher to use when combining the components of this instance.

public static func withClustering(
    map: Map,
    logicalPixel: LogicalPixel,
    maxZoom: Zoom,
    clusterRenderer: SimpleClusterRenderer,
    minZoom: Zoom = Zoom(value: 0),
    layerId: String? = nil
) -> MapObjectManager

Create IMapObjectManager with data clustering. Only IMarker objects are clustered.

Parameters
map
logicalPixel
LogicalPixel

Minimum possible distance on the screen between marker anchor points on levels where clustering works.

maxZoom
Zoom

The level from which all markers are visible.

clusterRenderer
SimpleClusterRenderer

Interface for specifying cluster display parameters.

minZoom
Zoom

The level from which clusters are formed.

layerId
String?

ID of a layer with "Dynamic object" style type. Created objects will be stored in this layer so that you can define their order relative to other layers. If not set, objects are stored above other layers.

Returns
public static func withGeneralization(
    map: Map,
    logicalPixel: LogicalPixel,
    maxZoom: Zoom,
    minZoom: Zoom = Zoom(value: 0),
    layerId: String? = nil
) -> MapObjectManager

Create IMapObjectManager with data generalization. Only IMarker objects are generalized.

Parameters
map
logicalPixel
LogicalPixel

The minimum possible distance on the screen between marker anchor points on the levels where generalization works.

maxZoom
Zoom

The level from which all markers are visible.

minZoom
Zoom

The level from which the generalization works.

layerId
String?

ID of a layer with "Dynamic object" style type. Created objects will be stored in this layer so that you can define their order relative to other layers. If not set, objects are stored above other layers.

Returns
public func addObject(
    item: SimpleMapObject
)

Adds an object.

Parameters
item
public func removeObject(
    item: SimpleMapObject
)

Removes an object.

Parameters
item
public func addObjects(
    objects: [SimpleMapObject]
)

Adds objects.

Parameters
objects
public func removeObjects(
    objects: [SimpleMapObject]
)

Removes objects.

Parameters
objects
public func removeAndAddObjects(
    objectsToRemove: [SimpleMapObject],
    objectsToAdd: [SimpleMapObject]
)

Removes and adds objects.

Parameters
objectsToRemove
objectsToAdd
public func removeAll()

public func clusteringObjects(
    position: CameraPosition
) -> [MapObject]

Gets the list of objects participating in clustering at the transmitted camera position. The list will contain both clusters and markers.

Parameters
position
Returns
Properties
var isVisible

Overrides the visibility of all objects added to the manager instance. The value false here takes precedence over the visibility of an individual object.
