Constructor Details

SingleTile

Creates a new blank Tile.

Parameters:

addr - the address

SingleTile

public SingleTile(TileAddress addr,
 BufferedImage img)

Creates a new Tile.

addr - the address

img - the BufferedImage

Method Details

setImage

public void setImage(BufferedImage img)

Description copied from interface: Tile

Sets the tile image.

Specified by:

setImage in interface Tile

Parameters:

img - the rendered image

getImage

public BufferedImage getImage()

Description copied from interface: RasterTile

Returns the rendered image.

Specified by:

getImage in interface RasterTile

Returns:

the image

isEmpty

public boolean isEmpty()

Returns whether this Tile has any data.

Returns:

TRUE if the Tile has no data, otherwise FALSE

isEmpty

public boolean isEmpty(TileAddress addr)

Returns whether a child of this Tile would be empty. This has the significant performance advantage since less data needs to be processed than if one generated the Tile and called isEmpty on it.

Parameters:

addr - the child Address

Returns:

FALSE if the Tile would be empty

Throws:

IllegalArgumentException - if addr's parent is not this Tile

NullPointerException - if addr is null
