GriddedSet, IrregularSet, ProductSet, SingletonSet, UnionSet
public abstract class SampledSet
extends SimpleSet
implements SampledSetIface

SampledSet is the abstract superclass of GriddedSets, PolyCells and MultiCells. SampledSet objects are intended to be immutable (but see getSamples(boolean) for an exception).

cram_missing

public void cram_missing(boolean[] range_select)
Overrides:
cram_missing in class Set

cram_samples

void cram_samples(float[][] samples)

getNeighbors

public void getNeighbors(int[][] neighbors,
                         float[][] weights)
                  throws VisADException
Overrides:

isMissing

public boolean isMissing()

getSamples

public float[][] getSamples()
                     throws VisADException

Returns a copy of the samples of this instance. Element [i][j] of the returned array is the j-th value of the i-th component.

This method is equivalent to getSamples(true).

Returns:
A copy of the sample array.
Overrides:
getSamples in class Set
See Also:
getSamples(boolean)

getSamples

public float[][] getSamples(boolean copy)
                     throws VisADException

Returns the samples of this instance or a copy of the samples.

Note that, if the actual sample array is returned, then it is possible to modify the values of this instance -- breaking the immutability aspect of this class. Don't do this unless you enjoy debugging.

Parameters:
copy - Whether or not a copy of the sample array should be returned.
Returns:
The sample array is copy is false; otherwise, a copy of the sample array.
Overrides:
getSamples in class Set
