Using tiling and multithreading

> > > > > >

To benefit from Rogue Wave® JViews Maps advanced image tiling capabilities and multithreading, use IlvTiledRasterDataSource in the place of IlvSDODataSource

Note

This assumes that you want to load an SDO layer containing raster objects, SDO_GEORASTER.

To use a tiled data source:

Instantiate a IlvRasterSDOReaderIlvRasterSDOReader object.

This class extends IlvRasterAbstractReaderIlvRasterAbstractReader and holds a list of raster elements. It fetches the following elements from the Oracle® DB

IlvSDOConnection SDOConnection; // the connection to your Oracle DB
String layerName;  // the name of the oracle layer containing SDO_GEORASTER
... // Initialize your connection.
IlvRasterSDOReader sdoReader = new
IlvRasterSDOReader(SDOConnection,layerName);

Create an IlvTiledRasterDataSourceIlvTiledRasterDataSource backed by the reader.

IlvTiledRasterDataSource tiledSource =
IlvRasterDataSourceFactory.buildTiledImageDataSource(
view.getManager(), sdoReader, true,true, null);

Configure the raster data source, and call the start() method to start data production.
```
tiledSource.setManager(view.getManager());
tiledSource.start();
```
