Interface PointSetRandomization

All Known Implementing Classes:

EmptyRandomization, LMScrambleShift, RandomShift, RandomStart, SMScrambleShift

public interface PointSetRandomization

This interface is used to randomize a PointSet. One can implement method randomize in any way. This method must use an internal RandomStream. This stream can be set in the constructor, but the methods getStream and setStream must be implemented.

The method randomize must be implemented using combinations of the randomization methods from the point set such as addRandomShift, leftMatrixScramble, stripedMatrixScramble, ...

If more than one PointSetRandomization is applied to the same point set, the randomizations will concatenate if they are of different types, but only the last of each type will remain.

Method Summary

RandomStream	getStream() Returns the internal RandomStream.
void	randomize(PointSet p) This method must randomize p.
void	setStream(RandomStream stream) Sets the internal RandomStream to stream.

Method Detail

randomize

void randomize(PointSet p)

Parameters:

p - Point set to randomize

setStream

void setStream(RandomStream stream)

Sets the internal RandomStream to stream.

Parameters:

stream - stream to use in the randomization

getStream

RandomStream getStream()

Returns the internal RandomStream.

Returns:

stream used in the randomization
