Constructor Detail

MercatorTiledImageLayer

public MercatorTiledImageLayer(LevelSet levelSet)

Method Detail

requestTexture

protected abstract void requestTexture(DrawContext dc,
                                       MercatorTextureTile tile)

forceTextureLoad

protected abstract void forceTextureLoad(MercatorTextureTile tile)

setName

public void setName(java.lang.String name)

Description copied from interface: Layer

Set the layer's name. The name is a convenience attribute typically used to identify the layer in user interfaces. By default, a layer has no name.

Specified by:

setName in interface Layer

Overrides:

setName in class AbstractLayer

Parameters:

name - the name to assign to the layer.

isUseTransparentTextures

public boolean isUseTransparentTextures()

setUseTransparentTextures

public void setUseTransparentTextures(boolean useTransparentTextures)

isForceLevelZeroLoads

public boolean isForceLevelZeroLoads()

setForceLevelZeroLoads

public void setForceLevelZeroLoads(boolean forceLevelZeroLoads)

isRetainLevelZeroTiles

public boolean isRetainLevelZeroTiles()

setRetainLevelZeroTiles

public void setRetainLevelZeroTiles(boolean retainLevelZeroTiles)

isDrawTileIDs

public boolean isDrawTileIDs()

setDrawTileIDs

public void setDrawTileIDs(boolean drawTileIDs)

isDrawTileBoundaries

public boolean isDrawTileBoundaries()

setDrawTileBoundaries

public void setDrawTileBoundaries(boolean drawTileBoundaries)

isShowImageTileOutlines

public boolean isShowImageTileOutlines()

setShowImageTileOutlines

public void setShowImageTileOutlines(boolean showImageTileOutlines)

isDrawBoundingVolumes

public boolean isDrawBoundingVolumes()

setDrawBoundingVolumes

public void setDrawBoundingVolumes(boolean drawBoundingVolumes)

getLevels

protected LevelSet getLevels()

getRequestQ

protected java.util.concurrent.PriorityBlockingQueue<java.lang.Runnable> getRequestQ()

isMultiResolution

public boolean isMultiResolution()

Description copied from interface: Layer

Indicates whether the layer provides multiple resolutions of imagery or other data.

Specified by:

isMultiResolution in interface Layer

Overrides:

isMultiResolution in class AbstractLayer

Returns:

true if the layer provides multiple resolutions, else false.

isAtMaxResolution

public boolean isAtMaxResolution()

Description copied from interface: Layer

Indicates whether the most recent rendering of the layer rendered the highest resolution imagery or other data available. Some layers do not track resolution. For those layers this value will always be true. Typically such layers also return false from Layer.isMultiResolution().

Specified by:

isAtMaxResolution in interface Layer

Overrides:

isAtMaxResolution in class AbstractLayer

Returns:

true if the layer is at maximum resolution, otherwise false.

isUseMipMaps

public boolean isUseMipMaps()

setUseMipMaps

public void setUseMipMaps(boolean useMipMaps)

render

public void render(DrawContext dc)

Description copied from interface: Layer

Cause the layer to draw its representation.

Specified by:

render in interface Layer

Overrides:

render in class AbstractLayer

Parameters:

dc - the current draw context

doRender

protected final void doRender(DrawContext dc)

Specified by:

doRender in class AbstractLayer

isLayerInView

public boolean isLayerInView(DrawContext dc)

Description copied from interface: Layer

Indicates whether the layer is in the view. The method implemented here is a default indicating the layer is in view. Subclasses able to determine their presence in the view should override this implementation.

Specified by:

isLayerInView in interface Layer

Overrides:

isLayerInView in class AbstractLayer

Parameters:

dc - the current draw context

Returns:

true if the layer is in the view, false otherwise.

getReferencePoint
