All Implemented Interfaces:

ArraySelectionAlgorithm

public class ArraySelectUnion

extends java.lang.Object

implements ArraySelectionAlgorithm

ArraySelectUnion is a ArraySelectionAlgorithm that will return the union of the results of two specified ArraySelectionAlgorithms.

Since:

JDK1.3

Constructor Summary

ArraySelectUnion(ArraySelectionAlgorithm first, ArraySelectionAlgorithm second)
Creates a new ArraySelectUnion object for taking the union of the Populations returned by the two passed ArraySelectionAlgorithms.

Method Summary

PopulationArray

selectFromPopulation(Population pop) Returns a Population that represents the union (junction) of the two ArraySelectionAlgorithms specified in the constructor.

Constructor Detail

ArraySelectUnion

public ArraySelectUnion(ArraySelectionAlgorithm first,
                        ArraySelectionAlgorithm second)

Creates a new ArraySelectUnion object for taking the union of the Populations returned by the two passed ArraySelectionAlgorithms.

Parameters:

first - the first ArraySelectionAlgorithm

second - the second ArraySelectionAlgorithm

Method Detail

selectFromPopulation

public PopulationArray selectFromPopulation(Population pop)

Returns a Population that represents the union (junction) of the two ArraySelectionAlgorithms specified in the constructor. The return is the result of the first selection algorithm, with the results of the second added to it via the Population.addCells() method. If the first selection algorithm returns a null then a NullPointerException will be thrown. If the second one returns a null, the the results of the first will be returned unchanged.

Specified by:

selectFromPopulation in interface ArraySelectionAlgorithm

Parameters:

pop - the Population to choose from

Returns:

the union Population of the two selection algorithms
