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).

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:

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.
