Hello all
BufferedImage implements WritableRenderedImage, but the javadoc of all
WritableRenderedImage methods are inconsistent with implementation:
* getWritableTile(…) said "All registered TileObservers are notified
when a tile goes from having no writers to having one writer" but
the implementation doesn't do that.
* releaseWritableTile(…) said "All registered TileObservers are
notified when a tile goes from having one writer to having no
writers" but the implementation does nothing.
* isTileWritable(…) said "throws ArrayIndexOutOfBoundsException if
both tileX and tileY are not equal to 0" but the implementation
throws IllegalArgumentException is *either* tileX or tileY is not 0.
* addTileObserver(…) and removeTileObserver(…) are no-op, but the
javadoc don't said that.
Should the javadoc be updated for saying that most methods are actually
no-op, or should the implementation be updated with real support of
listeners? Or should BufferedImage be considered as permanently checkout
out for writing, in which case the current javadoc is not wrong (except
above-cited throws clause) but a note about the "permanently
checkout-out" behavior would be helpfui?
