Class ArcGISTiledMapServiceLayer

java.lang.Object
  com.esri.map.Layer
      com.esri.map.ArcGISTiledMapServiceLayer

public class ArcGISTiledMapServiceLayer
extends Layer

An implementation of an ArcGIS Tiled Map Service. This class draws to a JComponent graphics context (JMap) and to an in-memory graphics context (JMap, Map) Additionally, it also draws its contents to an in-memory image maintained within this class for quick redraws of the contents of this individual layer if the state of the layer hasn't changed during a draw operation

Method Detail

internalInit

protected void internalInit()

createResolutionList

protected void createResolutionList(TileInfo tileInfo)

Creates the resolution list.

Parameters:

tileInfo - the tile info

getLegend

public LayerLegendInfoCollection getLegend()

Specified by:

getLegend in class Layer

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.

getPopupInfo

public ArcGISPopupInfo getPopupInfo(int sublayerId)

Overrides:

getPopupInfo in class Layer

getExtentBoundsOnScreen

protected Rectangle getExtentBoundsOnScreen()

getTileAsynch

protected void getTileAsynch(int lod,
                             int col,
                             int row,
                             com.esri.map.TiledMapServiceLayer.TileListener tilecallback)

initializeNativeLayer

protected void initializeNativeLayer()

Specified by:

initializeNativeLayer in class Layer

retrieveNoDataTileETag

protected void retrieveNoDataTileETag()

requestTile

protected void requestTile(int lod,
                           int col,
                           int row)
