DynamicLayer

public DynamicLayer()

Method Detail

getResolution

public double getResolution()

Description copied from class: Layer

Gets the resolution of the Layer.

Overrides:

getResolution in class Layer

Returns:

resolution.

getDefaultSpatialReference

public SpatialReference getDefaultSpatialReference()

Description copied from class: Layer

Gets the defaultSpatialReference of the Layer. For service layers this is defined by the service.

Overrides:

getDefaultSpatialReference in class Layer

Returns:

Returns the defaultSpatialReference.

setUrl

public void setUrl(String url)

Set the URL for the layer. This can only be set once.

Overrides:

setUrl in class Layer

Parameters:

url - The URL.

startlisteningToMapEvents

protected void startlisteningToMapEvents(JMap map)

Starts this layer listening to map events. This can be used, for example, to add a MapEventListener to the map.

Parameters:

map - The map to listen to.

stopListeningToMapEvents

protected void stopListeningToMapEvents(JMap map)

Stops this layer listening to map events. This can be used, for example, to remove a MapEventListener in the map.

Parameters:

map - The map to stop listening to.

refresh

public void refresh()

Force the map to redraw the layer. Does nothing if the layer has not been added to a map.

requestImage

protected void requestImage(int width,
                            int height,
