Constructor Detail

MemoryRasterDataContainer

public MemoryRasterDataContainer()

Creates an empty RasterDataContainer that stores the raster data in memory.

MemoryRasterDataContainer

public MemoryRasterDataContainer(RasterDataReader reader)

Reads RasterData from RasterReader and wraps it in a RasterDataContainer. RasterData stays in memory.

Parameters:

reader - RasterReader for RasterData

MemoryRasterDataContainer

public MemoryRasterDataContainer(RasterData raster)

Wraps RasterData in a RasterDataContainer. RasterData stays in memory.

Parameters:

raster - RasterData to wrap

Method Detail

getColumns

public int getColumns()

getRows

public int getRows()

getRasterData

public RasterData getRasterData()

Description copied from interface: RasterDataContainer

Returns the RasterData

Specified by:

getRasterData in interface RasterDataContainer

Returns:

RasterData

getReadOnlyRasterData

public RasterData getReadOnlyRasterData()

Description copied from interface: RasterDataContainer

Returns the RasterData as a read-only copy. Only a read-only RasterData supports thread-safe read operations.

Specified by:

getReadOnlyRasterData in interface RasterDataContainer

Returns:

RasterData

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

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
