void	loadData(IlvRasterMappedBuffer source, IlvRasterProperties properties) Method to load data when the tile loader needs it.
void	unloadData(IlvRasterMappedBuffer rasterMappedBuffer, IlvRasterProperties rasterProperties) Method to unload a tile content.

Method Detail

loadData

void loadData(IlvRasterMappedBuffer source,
              IlvRasterProperties properties)

Method to load data when the tile loader needs it. For example:

public void loadData(IlvRasterMappedBuffer source,IlvRasterProperties properties) {
  String fileName = properties.getBaseName();
  ... read the bytes deom the file ...
  source.setBytes(bytes);
} 
     

Parameters:

source - data Buffer to fill with data read on the fly.

properties - information attached to this buffer.

unloadData

void unloadData(IlvRasterMappedBuffer rasterMappedBuffer,
                IlvRasterProperties rasterProperties)

Method to unload a tile content.

Parameters:

rasterMappedBuffer - data Buffer to clear when tile is unloaded.

rasterProperties - information attached to this buffer.
