public interface TileObserver

An interface for objects that wish to be informed when tiles of a WritableRenderedImage become modifiable by some writer via a call to getWritableTile, and when they become unmodifiable via the last call to releaseWritableTile.

void tileUpdate(WritableRenderedImage source,
                int tileX,
                int tileY,
                boolean willBeWritable)

A tile is about to be updated (it is either about to be grabbed for writing, or it is being released from writing).

source - the image that owns the tile.
tileX - the X index of the tile that is being updated.
tileY - the Y index of the tile that is being updated.
willBeWritable - If true, the tile will be grabbed for writing; otherwise it is being released.
