Constructor Detail

CachedRasterDataContainer

public CachedRasterDataContainer()

Creates an empty RasterDataContainer that loads the data on first access.

CachedRasterDataContainer

public CachedRasterDataContainer(RasterDataReader reader)

Creates a RasterDataContainer that loads the data on first access.

Parameters:

reader - RasterReader for the raster source

Method Detail

setRasterDataReader

public void setRasterDataReader(RasterDataReader reader)

Description copied from interface: RasterDataContainer

Sets the source of the raster data.

Specified by:

setRasterDataReader in interface RasterDataContainer

Parameters:

reader - the raster data reader for this container

getRasterData

public RasterData getRasterData()

Description copied from interface: RasterDataContainer

Returns the RasterData

Specified by:

getRasterData in interface RasterDataContainer

Returns:

RasterData

getReadOnlyRasterData

public RasterData getReadOnlyRasterData()

getReadOnlyRasterData in interface RasterDataContainer

Returns:

RasterData

getRasterDataContainer

public RasterDataContainer getRasterDataContainer(RasterDataContainerFactory.LoadingPolicy type)

Description copied from interface: RasterDataContainerProvider

Returns a new RasterDataContainer for given type or null, if the implementation doesn't provide this type.

Specified by:

getRasterDataContainer in interface RasterDataContainerProvider

Returns:

a RasterDataContainer for given type or null
