Constructor Detail

GeneratorStatic

public GeneratorStatic(String name,
               LinkedList<Vector> points)

Construct generator using given name and points

Parameters:

name - Cluster name

points - Cluster points

Method Detail

generate

public List<Vector> generate(int count)

"Generate" new cluster points. Static generators always return their predefined set of points.

Specified by:

generate in interface GeneratorInterface

Parameters:

count - parameter is ignored.

Returns:

List of generated points

getDensity

public double getDensity(Vector p)

Get density at a given coordinate.

Specified by:

getDensity in interface GeneratorInterface

Parameters:

p - vector

Returns:

density

getDim

public int getDim()

Get cluster dimensionality

Specified by:

getDim in interface GeneratorInterface

Returns:

dimensionality

getDiscarded

public int getDiscarded()

Get number of discarded points

Returns:

number of discarded points

getName

public String getName()

Get cluster name

Specified by:

getName in interface GeneratorInterface

Returns:

cluster name

getPoints

public List<Vector> getPoints()

Get cluster points

Specified by:

getPoints in interface GeneratorInterface

Returns:

points

getSize

public int getSize()

Get cluster size

Specified by:

getSize in interface GeneratorInterface

Returns:

cluster size

setDiscarded

public void setDiscarded(int discarded)
                  throws UnableToComplyException

Notify cluster of discarded points. Not supported for static generators.

Parameters:

discarded - parameter not supported.

Throws:

UnableToComplyException - always thrown, since the static generator doesn't supprot discards.
