Method Summary

Modifier and Type	Method	Description
TileData	createData()	Subclasses must provide a fresh instance of TileData.
int	forEachTile(int tileWidth, int tileHeight, TileLoopIteration iteration)	Iterates over every tile in a given pixel based on the over arching dimensions and a requested maximum tile width and height.
Pixels	getPixels()	After saving the binary data, the update event of the Pixels instance will be updated and therefore need to be reloaded.
protected ServiceFactoryPrx	getSession()
void	setPixels(Pixels pixels)	Called by the TileData implementation to update the pixels instance for re-use by the client.

RPSTileLoop

public RPSTileLoop(ServiceFactoryPrx session,
                   Pixels pixels)

Method Detail

getSession

protected ServiceFactoryPrx getSession()

getPixels

public Pixels getPixels()

After saving the binary data, the update event of the Pixels instance will be updated and therefore need to be reloaded. As a convenience the returned value is accessible here.

setPixels

public void setPixels(Pixels pixels)

Called by the TileData implementation to update the pixels instance for re-use by the client.

createData

public TileData createData()

Description copied from class: TileLoop

Subclasses must provide a fresh instance of TileData. The instance will be closed after the run of TileLoop.forEachTile(int, int, int, int, int, int, int, TileLoopIteration).

Specified by:

createData in class TileLoop

Returns:

the new instance

forEachTile

public int forEachTile(int tileWidth,
                       int tileHeight,
                       TileLoopIteration iteration)
                throws ClientError,
                       ServerError

Iterates over every tile in a given pixel based on the over arching dimensions and a requested maximum tile width and height.

Parameters:

iteration - Invoker to call for each tile.

tileWidth - Maximum width of the tile requested. The tile request itself will be smaller than the original tile width requested if x + tileWidth > sizeX

tileHeight - Maximum height of the tile requested. The tile request itself will be smaller if y + tileHeight > sizeY.

Returns:

The total number of tiles iterated over.

Throws:

ClientError

ServerError
