Method Detail

createBuffer

public Buffer createBuffer(BufferParam param)
                    throws BufferCreationException

Description copied from interface: BufferFactory

Creates a buffer with the selected parameters

Specified by:

createBuffer in interface BufferFactory

Returns:

Throws:

BufferCreationException

createBufferParams

public BufferParam createBufferParams(int w,
                                      int h,
                                      int bandCount,
                                      int dataType,
                                      boolean malloc)

Description copied from interface: BufferFactory

Creates a parameter object for building a buffer. The buffer type is read-write. This type could be changed after the creation of a BufferParam object. The buffer will be cached if it's necessary

Specified by:

createBufferParams in interface BufferFactory

Parameters:

w - Width

h - Height

bandCount - Number of bands

dataType - Type of data

createMemoryBufferParams

public BufferParam createMemoryBufferParams(int w,
                                            int h,
                                            int bandCount,
                                            int dataType,
                                            boolean malloc)

Description copied from interface: BufferFactory

Creates a parameter object for building a buffer. The buffer type is read-write. This type could be changed after the creation of a BufferParam object. The buffer will be stored in memory.

Specified by:

createMemoryBufferParams in interface BufferFactory

Parameters:

w - Width

h - Height

bandCount - Number of bands

dataType - Type of data

createReadOnlyBufferParams

public BufferParam createReadOnlyBufferParams(RasterDataStore store,
                                              int minx,
                                              int miny,
                                              int maxx,
                                              int maxy,
                                              BandList bandList)

Description copied from interface: BufferFactory

Creates a parameter object for building a buffer. For this call the buffer type is read-only.

Specified by:

createReadOnlyBufferParams in interface BufferFactory

Returns:

BufferParam
