All Implemented Interfaces:

Serializable, Cloneable, Data, SampledSetIface, SetIface, SimpleSetIface, Thing

Direct Known Subclasses:

GriddedSet, IrregularSet, ProductSet, SingletonSet, UnionSet

public abstract class SampledSet
extends SimpleSet

DataShadow	computeRanges(ShadowType type, DataShadow shadow) Recursive version of computeRanges(), called down through Data object tree.
DataShadow	computeRanges(ShadowType type, DataShadow shadow, double[][] ranges, boolean domain) this default does not set ranges - it is used by FloatSet and DoubleSet

isMissing

public boolean isMissing()

Specified by:

Returns:

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).

Specified by:

Returns:

A copy of the sample array.

Throws:

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.

Specified by:

getSamples in interface SetIface

Overrides:

getSamples in class Set

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.

Throws:
