                                              AVList params)

This returns a new sub-raster initialized with the specified properties. Called from doGetSubRaster to create the sub-raster instance before populating its contents. This does not place any restrictions on the specified width, height, sector or params.

This returns a BufferWrapper.ByteBufferWrapper, a subclass of BufferWrapperRaster backed by a ByteBuffer.

Parameters:

width - the width of the sub-raster, in pixels.

height - the height of the sub-raster, in pixels.

sector - the sector the sub-raster occupies.

params - the parameters associated with the sub-raster.

Returns:

a new sub-raster initialized with the specified width, height, sector and params.

dispose

public void dispose()

Description copied from interface: Disposable

Disposes of any internal resources allocated by the object.

Specified by:

dispose in interface Disposable

doDrawOnTo

protected void doDrawOnTo(BufferWrapperRaster canvas)

drawOnTo

public void drawOnTo(DataRaster canvas)

Description copied from interface: DataRaster

Copies this raster into a specified raster.

Specified by:

drawOnTo in interface DataRaster

Parameters:

canvas - - the raster to copy into.

fill

public void fill(double value)

get

protected void get(int x,
                   int y,
                   int length,
                   double[] buffer,
                   int pos)

getBuffer

public BufferWrapper getBuffer()

getDoubleAtPosition

public double getDoubleAtPosition(int row,
                                  int col)

getExtremes

public double[] getExtremes()

Returns a two-element array containing this raster's extreme scalar values, ignoring any values marked as missing-data. This returns null if this raster contains no values, or if it contains only values marked as missing-data.

Returns:

a two-element array containing this raster's extreme values, or null if none exist. Entry 0 contains the minimum value; entry 1 contains the maximum value.

getSizeInBytes

public long getSizeInBytes()

Description copied from interface: Cacheable

Retrieves the approximate size of this object in bytes. Implementors are encouraged to calculate the exact size for smaller objects, but use approximate values for objects that include such large components that the approximation would produce an error so small that the extra computation would be wasteful.

Specified by:

getSizeInBytes in interface Cacheable

Returns:

this Cacheable object's size in bytes
