Examples of TileComputationListener

com.lightcrafts.mediax.jai.TileComputationListener
Interface to monitor tiles which have been submitted to the TileScheduler for non-prefetch background processing. The request parameter of each method corresponds to the value returned by the method used to queue the tiles, i.e., TileScheduler.scheduleTiles() or more commonly PlanarImage.queueTiles(). The eventSource parameter provides the identity of the emitter of the event. If the event is emitted by the TileScheduler itself this will be a reference to the TileScheduler object; if it is emitted by a RenderedOp this will be the RenderedOp node. The image parameter will in all cases be the image actually specified to the TileScheduler.
With respect to standard rendered imaging chains consisting of RenderedOp nodes, any TileComputationListeners registered with the RenderedOp itself will receive events from the RenderedOp so that the event source will be the RenderedOp. If the listener is registered with the rendering of the node, then the event source will likely be the TileScheduler itself. This is definitely the case if the rendering is either an OpImage or is a PlanarImage which has not overridden queueTiles().
The image parameter passed to any registered listener of a RenderedOp will contain a reference to the rendering of the node rather than to the node itself.
For a given TileComputationListener exactly one of the tile status callbacks should be invoked during the life cycle of a given tile in the TileScheduler. @see TileScheduler @see TileRequest @see RenderedOp @see OpImage @since JAI 1.1
