Method Detail

setMap

public void setMap(GoogleMap map)

Changes the map that GeoJsonFeature objects are being drawn onto. Existing objects are removed from the previous map and drawn onto the new map.

Overrides:

setMap in class Renderer

Parameters:

map - GoogleMap to place GeoJsonFeature objects on

addLayerToMap

public void addLayerToMap()

Adds all of the stored features in the layer onto the map if the layer is not already on the map.

addFeature

public void addFeature(GeoJsonFeature feature)

Adds a new GeoJsonFeature to the map if its geometry property is not null.

Parameters:

feature - feature to add to the map

removeLayerFromMap

public void removeLayerFromMap()

Removes all GeoJsonFeature objects stored in the mFeatures hashmap from the map

removeFeature

public void removeFeature(GeoJsonFeature feature)

Removes a GeoJsonFeature from the map if its geometry property is not null

Parameters:

feature - feature to remove from map

update

public void update(java.util.Observable observable,
                   java.lang.Object data)

Update is called if the developer sets a style or geometry in a GeoJsonFeature object

Specified by:

update in interface java.util.Observer

Parameters:

observable - GeoJsonFeature object

data - null, no extra argument is passed through the notifyObservers method
