All Implemented Interfaces:

SafeDisposable

public class SoCpuBufferCompressed
extends SoCpuBufferObject

LDM buffer object optimized for compressed tile data. This type of buffer efficiently represents a tile containing compressed data (usually read from a compressed LDM file). The buffer can be used like any other buffer, but uses much less memory when its contents are not actually being accessed.

Constructor Detail

SoCpuBufferCompressed

public SoCpuBufferCompressed()

Default constructor.

SoCpuBufferCompressed

public SoCpuBufferCompressed(SoDataCompressor compressor)

Constructor with compressor given as parameter.

Method Detail

setMinMax

public void setMinMax(double min,
                      double max)

Set the min and max values for this buffer.

Parameters:

min - user variable containing min value

max - user variable containing max value

getRealSize

public long getRealSize()

Returns the size of the uncompressed data in bytes.

setCompressor

public void setCompressor(SoDataCompressor compressor)

Set the compressor used to decompress buffer.

Parameters:

compressor - Pointer to the compressor to use

getMinMax

public double[] getMinMax()

Get the min and max values in the buffer, if they are known.
Returns false if these values have not been set or computed. Returns true if values are available.

Parameters:

min - user variable to store min value

max - user variable to store max value
