Constructor Detail

SoCpuBufferFromVolumeReader

public SoCpuBufferFromVolumeReader(SoDataSet dataset,
                                   SoLDMTileID tileId)

Constructor with dataset and tile Id as parameter.

Parameters:

dataset - pointer to dataset associated with buffer

tileId - tileId representing the tile the buffer will store

Method Detail

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

getRealSize

public long getRealSize()

Returns the real size of the buffer in bytes.
