getAvailableImageFormats

public List<String> getAvailableImageFormats()

getDefaultImageFormat

public String getDefaultImageFormat()

getRequestQ

protected PriorityBlockingQueue<Runnable> getRequestQ()

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.

isDrawBoundingVolumes

public boolean isDrawBoundingVolumes()

isDrawTileBoundaries

public boolean isDrawTileBoundaries()

isDrawTileIDs

public boolean isDrawTileIDs()

isForceLevelZeroLoads

public boolean isForceLevelZeroLoads()

isImageFormatAvailable

public boolean isImageFormatAvailable(String imageFormat)

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.

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.

isRetainLevelZeroTiles

public boolean isRetainLevelZeroTiles()

isShowImageTileOutlines

public boolean isShowImageTileOutlines()

isUseMipMaps

public boolean isUseMipMaps()

isUseTransparentTextures

public boolean isUseTransparentTextures()

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

requestTexture

protected abstract void requestTexture(DrawContext dc,
                                       MercatorTextureTile tile)

setAvailableImageFormats

protected void setAvailableImageFormats(String[] formats)

setDrawBoundingVolumes

public void setDrawBoundingVolumes(boolean drawBoundingVolumes)

setDrawTileBoundaries

public void setDrawTileBoundaries(boolean drawTileBoundaries)

setDrawTileIDs

public void setDrawTileIDs(boolean drawTileIDs)

setForceLevelZeroLoads

public void setForceLevelZeroLoads(boolean forceLevelZeroLoads)

setName

public void setName(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.

setRetainLevelZeroTiles

public void setRetainLevelZeroTiles(boolean retainLevelZeroTiles)

setShowImageTileOutlines

public void setShowImageTileOutlines(boolean showImageTileOutlines)

setUseMipMaps

public void setUseMipMaps(boolean useMipMaps)

setUseTransparentTextures

public void setUseTransparentTextures(boolean useTransparentTextures)
