Constructor Detail

ProductComponentLink

public ProductComponentLink(IProductComponentGeneration source)

Creates a new link for the given product component generation. Target and cardinality must be set by invoking initFromXml.

ProductComponentLink

public ProductComponentLink(IProductComponentGeneration source,
                            T target)

Creates a new link to the given target for the given product component generation using the cardinality (0,*).

Throws:

NullPointerException - if any of the parameters is null.

ProductComponentLink

public ProductComponentLink(IProductComponentGeneration source,
                            T target,
                            CardinalityRange cardinality)

Creates a new link with the given cardinality to the given target for the given product component generation.

Throws:

NullPointerException - if any of the parameters is null.

ProductComponentLink

public ProductComponentLink(IProductComponentLinkSource source)

Creates a new link for the given product component generation. Target and cardinality must be set by invoking initFromXml.

ProductComponentLink

public ProductComponentLink(IProductComponentLinkSource source,
                            T target)

Creates a new link to the given target for the given product component generation using the cardinality (0,*).

Throws:

NullPointerException - if any of the parameters is null.

ProductComponentLink

public ProductComponentLink(IProductComponentLinkSource source,
                            T target,
                            CardinalityRange cardinality)

Creates a new link with the given cardinality to the given target for the given product component generation.

Throws:

NullPointerException - if any of the parameters is null.

Method Detail

getCardinality

public CardinalityRange getCardinality()

Specified by:

getCardinality in interface IProductComponentLink<T extends IProductComponent>

Returns:

this link's min and max cardinality as a IntegerRange.

initFromXml

public void initFromXml(Element element)

Description copied from interface: IClRepositoryObject
