java.lang.Object
  dk.rode.thesis.abstractfactory.RangeValueFactory

All Implemented Interfaces:

GeneratorFactory<Integer,Integer[]>

@ParticipantUsage(value="ConcreteProduct",
                  type=SequenceValueRange.class)
@Participant(value="ConcreteFactory")
public class RangeValueFactory
extends Object
implements GeneratorFactory<Integer,Integer[]>

A range value factory creates value range generators.

This factory is thread-safe.

Author:

Field Summary

private Integer[]

defaultMinMax The default range for the created generators.

Constructor Summary

RangeValueFactory(int minimum)
Constructor, which creates this factory to use the minimum value of minimum for all created generators.

RangeValueFactory(int minimum, int maximum)
Constructor, which creates this factory to use the minimum value of minimum for all created generators.

Method Summary

SequenceValueRange	createGenerator() Creates a new sequence value generator using the default argument.
SequenceValueRange	createGenerator(Integer[] minMax) Creates a new sequence value generator, where argument is an argument used in the creation process of the generator.
Integer[]	getDefaultArgument() Returns the default argument to use for generator creation in case no argument is supplied to the GeneratorFactory.createGenerator(Object) method.
String	toString() Returns the string representation of this factory.

Field Detail

defaultMinMax

private final Integer[] defaultMinMax

The default range for the created generators.

Length = 1: minimum range, no upper value.

Length = 2: minimum and maximum.

Never null.

Constructor Detail

RangeValueFactory

public RangeValueFactory(int minimum)

Constructor, which creates this factory to use the minimum value of minimum for all created generators.

Parameters:

minimum - The minimum value.

RangeValueFactory

public RangeValueFactory(int minimum,
                         int maximum)

Constructor, which creates this factory to use the minimum value of minimum for all created generators.

Parameters:

minimum - The minimum value.

maximum - The maximum value.

Throws:

IllegalArgumentException - If minimum is larger than maximum.

Method Detail

createGenerator

public SequenceValueRange createGenerator()

Description copied from interface: GeneratorFactory

Creates a new sequence value generator using the default argument.

Specified by:

createGenerator in interface GeneratorFactory<Integer,Integer[]>

Returns:

A new created generator; never null.

GeneratorFactory.createGenerator(Object), GeneratorFactory.getDefaultArgument()

createGenerator

public SequenceValueRange createGenerator(Integer[] minMax)

Description copied from interface: GeneratorFactory

Creates a new sequence value generator, where argument is an argument used in the creation process of the generator.

Specified by:

createGenerator in interface GeneratorFactory<Integer,Integer[]>

Parameters:

minMax - The range, where a length of one indicates a minimum only, and a length of two indicates a minimum and maximum value; can be null, in which case the default range is used.

Returns:

A new created generator; never null.

Throws:

IllegalArgumentException - If minimum is larger than maximum.

GeneratorFactory.createGenerator()

getDefaultArgument

public Integer[] getDefaultArgument()

Description copied from interface: GeneratorFactory

Returns the default argument to use for generator creation in case no argument is supplied to the GeneratorFactory.createGenerator(Object) method.

Specified by:

getDefaultArgument in interface GeneratorFactory<Integer,Integer[]>

Returns:

The default argument, if any; can be null, depending on the actual implementation.

toString

public String toString()

Returns the string representation of this factory.

Overrides:

toString in class Object

Returns:

The string representation; never null.
