javax.media.jai.WritableRenderedImageAdapter
| WritableRenderedImageAdapter | | final public class WritableRenderedImageAdapter extends RenderedImageAdapter implements WritableRenderedImage(Code) | | A PlanarImage wrapper for a
WritableRenderedImage. The tile layout, sample model,
and so forth are preserved. Calls to getTile() and so
forth are forwarded.
From JAI's point of view, this image is a
PlanarImage of unknown type, with no sources, and
additionally an implementer of the
WritableRenderedImage interface. The image's pixel
data appear to be variable.
The class and all its methods are marked final in
order to allow dynamic inlining to take place. This should
eliminate any performance penalty associated with the use of an
adapter class.

| Constructor Summary | |
| public | WritableRenderedImageAdapter(WritableRenderedImage im)
Constructs a WritableRenderedImageAdapter.
Parameters:
im - A WritableRenderedImage to be `wrapped'as a PlanarImage. |
| Method Summary | |
| final public void | addTileObserver(TileObserver tileObserver)
Adds an observer. | | final public WritableRaster | getWritableTile(int tileX, int tileY)
Checks out a tile for writing. | | final public Point[] | getWritableTileIndices()
Returns an array of Point objects indicating which tiles
are checked out for writing. | | final public boolean | hasTileWriters()
Returns whether any tile is checked out for writing. | | final public boolean | isTileWritable(int tileX, int tileY)
Returns whether a tile is currently checked out for writing.
Parameters:
tileX - The X index of the tile.
Parameters:
tileY - The Y index of the tile. | | final public void | releaseWritableTile(int tileX, int tileY)
Relinquishes the right to write to a tile. | | final public void | removeTileObserver(TileObserver tileObserver)
Removes an observer. | | final public void | setData(Raster raster)
Sets a rectangular region of the image to the contents of
raster.
Parameters:
raster - A Raster. |
| WritableRenderedImageAdapter | | public WritableRenderedImageAdapter(WritableRenderedImage im)(Code) | | Constructs a WritableRenderedImageAdapter.
Parameters:
im - A WritableRenderedImage to be `wrapped'as a PlanarImage. IllegalArgumentException if im isnull. |
| addTileObserver | | final public void addTileObserver(TileObserver tileObserver)(Code) | | Adds an observer. If the observer is already present,
it will receive multiple notifications.
Parameters:
tileObserver - The TileObserver to be added. IllegalArgumentException iftileObserver is null. |
| getWritableTile | | final public WritableRaster getWritableTile(int tileX, int tileY)(Code) | | Checks out a tile for writing.
The WritableRenderedImage is responsible for
notifying all of its TileObservers when a tile
goes from having no writers to having one writer.
Parameters:
tileX - The X index of the tile.
Parameters:
tileY - The Y index of the tile. The tile as a WritableRaster. |
| getWritableTileIndices | | final public Point[] getWritableTileIndices()(Code) | | Returns an array of Point objects indicating which tiles
are checked out for writing.
an array of Points or null if notiles are checked out for writing. |
| hasTileWriters | | final public boolean hasTileWriters()(Code) | | Returns whether any tile is checked out for writing.
Semantically equivalent to (getWritableTiles().size() != 0).
true if any tile currently has writers. |
| isTileWritable | | final public boolean isTileWritable(int tileX, int tileY)(Code) | | Returns whether a tile is currently checked out for writing.
Parameters:
tileX - The X index of the tile.
Parameters:
tileY - The Y index of the tile. true if the tile currently has writers. |
| releaseWritableTile | | final public void releaseWritableTile(int tileX, int tileY)(Code) | | Relinquishes the right to write to a tile. If the caller
continues to write to the tile, the results are undefined.
Calls to this method should only appear in matching pairs with
calls to getWritableTile(); any other use will
lead to undefined results.
The WritableRenderedImage is responsible for
notifying all of its TileObservers when a tile
goes from having one writer to having no writers.
Parameters:
tileX - The X index of the tile.
Parameters:
tileY - The Y index of the tile. |
| removeTileObserver | | final public void removeTileObserver(TileObserver tileObserver)(Code) | | 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:
tileObserver - The TileObserver to be removed. IllegalArgumentException iftileObserver is null. |
| setData | | final public void setData(Raster raster)(Code) | | Sets a rectangular region of the image to the contents of
raster.
Parameters:
raster - A Raster. IllegalArgumentException if raster isnull. |
