public void addTileObserver (TileObserver to)

Adds an observer.

Adds an observer. If the observer is already present,
it will receive multiple notifications.
Parameters:
- to - the specified TileObserver

public WritableRaster getWritableTile (int tileX, int tileY)

Checks out a tile for writing.

public Point getWritableTileIndices ()

Returns an array of Point objects indicating which tiles are checked out for writing.

public boolean hasTileWriters ()

Returns whether any tile is checked out for writing.

Returns whether any tile is checked out for writing.
Semantically equivalent to (getWritableTileIndices() != null).
Returns: true if any tiles are checked out for writing; false otherwise.

public boolean isTileWritable (int tileX, int tileY)

Returns whether a tile is currently checked out for writing.

Returns whether a tile is currently checked out for writing.
Returns: true if specified tile is checked out for writing; false otherwise.
Parameters:
- tileX - the X index of the tile.
- tileY - the Y index of the tile.

public void releaseWritableTile (int tileX, int tileY)

Relinquishes the right to write to a tile.

public void removeTileObserver (TileObserver to)

Removes an observer.

Removes an observer. If the observer was not registered,
nothing happens. If the observer was registered for multiple
notifications, it will now be registered for one fewer.
Parameters:
- to - the specified TileObserver

public void setData (Raster r)

Sets a rect of the image to the contents of the Raster r, which is assumed to be in the same coordinate space as the WritableRenderedImage.

Sets a rect of the image to the contents of the Raster r, which is
assumed to be in the same coordinate space as the WritableRenderedImage.
The operation is clipped to the bounds of the WritableRenderedImage.
Parameters:
- r - the specified Raster
