Method Details

getType

public ProductCmptType getType()

Returns the ProductCmptType this attribute belongs to.

Overrides:

getType in class TypePart

getModelType

@Deprecated
public ProductCmptType getModelType()

Deprecated.

Use getType()

Returns the parent Type

Overrides:

getModelType in class TypePart

isProductRelevant

public boolean isProductRelevant()

Description copied from class: Attribute

Returns true if this attribute is configured by the product. Product attributes are always product relevant.

Specified by:

isProductRelevant in class Attribute

Returns:

true if this attribute is configured by the product, false if not

createOverwritingAttributeFor

public Attribute createOverwritingAttributeFor(Type subType)

Description copied from class: Attribute

Creates an attribute model for a sub type in which this attribute is overwritten. This is necessary to retrieve information contained in the class annotation such as labels if no getter is generated for the overwritten attribute in the sub class.

Specified by:

createOverwritingAttributeFor in class Attribute

Parameters:

subType - a model type representing a sub type of this attribute's model type

Returns:

a Attribute for the given sub model type

getValue

public Object getValue(IProductComponent productComponent,
 Calendar effectiveDate)

Returns the value of this attribute in the given product component (or its generation identified by the effectiveDate, if the attribute is changeable over time).

It is safe to cast the returned object to the class returned by Attribute.getDatatype(), except when the attribute is a multi-value attribute - then a List is returned (and it's contents can be cast to the class returned by Attribute.getDatatype()).

Parameters:

productComponent - a product component based on the product component type this attribute belongs to.

effectiveDate - (optional) the date to use for selecting the product component's generation, if this attribute Attribute.isChangingOverTime()

isMultiValue

public Boolean isMultiValue()

Whether this attribute has just one value or multiple values. If the attribute has multiple values, Attribute.getDatatype() will still return the class of a single value, but getValue(IProductComponent, Calendar) will return a List.
