Constructor Detail

PolicyAttribute

public PolicyAttribute(Type type,
               IpsAttribute attributeAnnotation,
               IpsExtensionProperties extensionProperties,
               Class<?> datatype,
               boolean changingOverTime)

Method Detail

getType

public PolicyCmptType getType()

Returns the PolicyCmptType this attribute belongs to.

Overrides:

getType in class TypePart

getModelType

@Deprecated
public PolicyCmptType getModelType()

Deprecated. Use getType()

Returns the parent Type

Specified by:

getModelType in interface IModelTypeAttribute

Overrides:

getModelType in class TypePart

getValue

public abstract Object getValue(IModelObject modelObject)

Returns the value of the given model object's attribute identified by this model type attribute.

Parameters:

modelObject - a model object corresponding to the Type this attribute belongs to

Returns:

the value of the given model object's attribute identified by this model type attribute

Throws:

IllegalArgumentException - if the model object does not have an attribute fitting this model type attribute or that attribute is not accessible for any reason

setValue

public abstract void setValue(IModelObject modelObject,
            Object value)

Sets the given model object's attribute identified by this model type attribute to the given value. This only works for changeable attributes.

Parameters:

modelObject - a model object corresponding to the Type this attribute belongs to

value - an object of this model type attribute's datatype

Throws:

IllegalArgumentException - if the model object does not have a changeable attribute fitting this model type attribute or that attribute is not accessible for any reason or the value does not fit the attribute's datatype.

getDefaultValue

public abstract Object getDefaultValue(IConfigurableModelObject modelObject)

Returns the product configured default value of the attribute identified by this model type attribute. Throws an IllegalArgumentException if the model object has no getDefaultValue() method for this attribute. This also occurs if the corresponding policy class is not configured by a product class.

Parameters:

modelObject - the configurable model object from which product component and (if necessary) effective date can be retrieved

See Also:

getDefaultValue(IProductComponent, Calendar)

getDefaultValue

public abstract Object getDefaultValue(IProductComponent source,
                     Calendar effectiveDate)

Returns the product configured default value of the attribute identified by this model type attribute. Throws an IllegalArgumentException if the model object has no getDefaultValue() method for this attribute. This also occurs if the corresponding policy class is not configured by a product class.

Parameters:

source - the product component to read the attribute default value from.

effectiveDate - the date to determine the product component generation. If null the latest generation is used. Is ignored if the attribute's configuration is not changing over time.

getValueSet

public abstract org.faktorips.valueset.ValueSet<?> getValueSet(IModelObject modelObject,
                                             IValidationContext context)

Returns the value set of the given model object's attribute identified by this model type attribute. Throws an IllegalArgumentException if the model object has no getAllowedValues() method for this attribute. This also occurs if the corresponding policy class is not configured by a product class.

Parameters:

modelObject - a model object

getValueSet

public abstract org.faktorips.valueset.ValueSet<?> getValueSet(IProductComponent source,
                                             Calendar effectiveDate,
                                             IValidationContext context)

Returns the value set of the given model object's attribute identified by this model type attribute. Throws an IllegalArgumentException if the model object has no getAllowedValues() method for this attribute. This also occurs if the corresponding policy class is not configured by a product class.

Parameters:

source - the product component to read an attribute value set from. Must correspond to the Type this attribute belongs to.

effectiveDate - the date to determine the product component generation. If null the latest generation is used. Is ignored if the attribute's configuration is not changing over time.
