Class ProductComponent

java.lang.Object

org.faktorips.runtime.internal.RuntimeObject

org.faktorips.runtime.internal.ProductComponent

All Implemented Interfaces:

IClRepositoryObject, IXmlPersistenceSupport, IProductComponent, IProductComponentLinkSource, IProductObject, IRuntimeObject

public abstract class ProductComponent
extends RuntimeObject
implements IProductComponent, IXmlPersistenceSupport

Base class for all product components.

Deliberately implements IXmlPersistenceSupport directly. Letting IProductComponent extend IXmlPersistenceSupport would have published it, which is undesired.

Constructor Detail

ProductComponent

public ProductComponent(IRuntimeRepository repository,
                        String id,
                        String productKindId,
                        String versionId)

Creates a new product component with the indicate id, kind id and version id.

Parameters:

repository - The component registry the component uses to resolve references to other components.

id - The component's runtime id.

productKindId - The component's kind id

versionId - The component's version id

Throws:

NullPointerException - if repository, id, productKindId, or versionId is null.

Method Detail

getKindId

public String getKindId()

Description copied from interface: IProductComponent

Returns the id of the product component kind that this product component belongs to.

Specified by:

getKindId in interface IProductComponent

getVersionId

public String getVersionId()

Description copied from interface: IProductComponent

Returns the version id that identifies this product component in its kind.

Specified by:

getVersionId in interface IProductComponent

getId

public String getId()

Description copied from interface: IProductComponent

Returns the product component's id that uniquely identifies it in the repository it belongs to.

Specified by:

getId in interface IProductComponent

isVariant

public boolean isVariant()

Description copied from interface: IProductComponent

A variant is a product component that is based on another product component (hence varied base). It uses the varied base as a template and "changes" specific values.

Specified by:

isVariant in interface IProductComponent

Returns:

true if this is a variant of another IProductComponent, false for regular product components.

See Also:

IProductComponent.getVariedBase()

getVariedBase

public IProductComponent getVariedBase()

Description copied from interface: IProductComponent

Allows distinguishing variants not only by their product component type but also their varied base. IProductComponent.isVariant() allows determining whether a product component is a variant.

Specified by:

getVariedBase in interface IProductComponent

Returns:

the IProductComponent this IProductComponent is based on. Returns null if it is a regular product component or the variedBase can not be found in the IRuntimeRepository.

See Also:

IProductComponent.isVariant(), IRuntimeRepository.getProductComponent(String)

getValidFrom

public DateTime getValidFrom()

Description copied from interface: IProductObject

Returns the date from which this generation is valid.

Specified by:

getValidFrom in interface IProductObject

Returns:

The valid from date of this generation

getValidFrom

public Date getValidFrom(TimeZone zone)

Description copied from interface: IProductObject

Returns the point in time this generation is valid from in the given time zone. This method never returns null.

Specified by:

getValidFrom in interface IProductObject

setValidFrom

public void setValidFrom(DateTime validfrom)

Sets the new valid from date.

Attention: Conceptually, the valid from date of the first generation must be equal to the valid from date of the product component itself. Therefore, if clients call this method, then to achieve data consistency clients must set the valid from date of the first generation, too.

Throws:

IllegalRepositoryModificationException - if the repository this product component belongs to does not allow to modify its contents

See Also:

ProductComponentGeneration.setValidFrom(DateTime)

getValidTo

public DateTime getValidTo()

Description copied from interface: IProductComponent

Returns the date when this product component expires. Returning null means no end of the validity period.

Specified by:

getValidTo in interface IProductComponent

setValidTo

public void setValidTo(DateTime validTo)

getRepository

public IRuntimeRepository getRepository()

Description copied from interface: IProductComponent

Returns the repository this product component belongs to. This method never returns null.

Specified by:

getRepository in interface IProductComponent

Specified by:

getRepository in interface IProductComponentLinkSource

Returns:

The IRuntimeRepository that was used to create this IProductComponentLinkSource

getGenerationBase

public IProductComponentGeneration getGenerationBase(Calendar effectiveDate)

Description copied from interface: IProductComponent

Returns the generation that is effective on the given date or null if no generation is effective on that date.

Specified by:

getGenerationBase in interface IProductComponent

getLatestProductComponentGeneration

public IProductComponentGeneration getLatestProductComponentGeneration()

Description copied from interface: IProductComponent

Returns the latest product component generation of the provided product component or null if non available.

Specified by:

getLatestProductComponentGeneration in interface IProductComponent

getFormulaEvaluator

public IFormulaEvaluator getFormulaEvaluator()

getDescription

public String getDescription(Locale locale)

Description copied from interface: IProductComponent

Returns the description for this product component in the specified locale. If there is no description in the specified locale, it tries to find the description in the locale's language. If there is also no description in the locale's language it returns the empty string.

Specified by:

getDescription in interface IProductComponent

Returns:

the description for the given locale/language or an empty string if no description exists for the given locale

initFromXml

public void initFromXml(Element cmptElement)

Initializes the generation with the data from the xml element.
