GLMapMarkerLayer

public GLMapMarkerLayer(@Nullable
                        java.lang.Object[] markers,
                        @NonNull
                        GLMapMarkerStyleCollection styleCollection,
                        double clusteringRadius,
                        int drawOrder)

Initializes GLMapMarkerLayer with given markers and `styleCollection`

Parameters:

markers - Array of marker objects. Usually you set objects with data, that you need to display on map.

styleCollection - A style collection object used to display markers.

drawOrder - Draw order used to sort objects on map

clusteringRadius - Radius of clustering in points. If 0 marker clustering will be disabled

GLMapMarkerLayer

public GLMapMarkerLayer(@NonNull
                        GLMapVectorObjectList objects,
                        @NonNull
                        GLMapVectorCascadeStyle cascadeStyle,
                        @NonNull
                        GLMapMarkerStyleCollection styleCollection,
                        double clusteringRadius,
                        int drawOrder)

Initializes GLMapMarkerLayer with given vector objects and `style`

Parameters:

objects - Array of marker objects. Usually you set objects with data, that you need to display on map.

cascadeStyle - A cascadeStyle that defines what style use for markers and unions

styleCollection - A style collection object used to display markers.

drawOrder - Draw order used to sort objects on map

clusteringRadius - Radius of clustering in points. If 0 marker clustering will be disabled

objectsNearPoint

@Nullable
public java.lang.Object[] objectsNearPoint(@NonNull
                                           GLMapViewRenderer mapView,
                                           @NonNull

                                           double distanceInPoints)

Searches nearest object or cluster of objects at given mapView Note that GLMapView must be dispalyed on screen to calculate distances.

Parameters:

mapView - map view where layer is displayed

point - point where object(s) will be searched

distanceInPoints - maximum hit distance in points

Returns:

First object or cluster distance of which is not greater that given distance

haveObject

public boolean haveObject(java.lang.Object marker)

Checks if given marker is added to layer

Parameters:

marker - marker to check

Returns:

true if object is in marker layer
