Constructor Summary

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

MemoryRasterDataContainer(RasterData raster)
Wraps RasterData in a RasterDataContainer.

MemoryRasterDataContainer(RasterDataReader reader)
Reads RasterData from RasterReader and wraps it in a RasterDataContainer.

Method Summary

int	getColumns() Returns the columns / width in pixel of the raster
RasterData	getRasterData() Returns the RasterData
RasterDataContainer	getRasterDataContainer(RasterDataContainerFactory.LoadingPolicy type) Returns a new RasterDataContainer for given type or null, if the implementation doesn't provide this type.
RasterData	getReadOnlyRasterData() Returns the RasterData as a read-only copy.
int	getRows() Returns the rows / height in pixel of the raster
void	setRasterDataReader(RasterDataReader reader) Sets the source of the raster data.

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()

Description copied from interface: RasterDataContainer

Returns the columns / width in pixel of the raster

Specified by:

getColumns in interface RasterDataContainer

Returns:

columns of the raster

getRows

public int getRows()

Description copied from interface: RasterDataContainer

Returns the rows / height in pixel of the raster

Specified by:

getRows in interface RasterDataContainer

Returns:

rows of the raster

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
