Constructor Detail

ConstantPolicyAttribute

public ConstantPolicyAttribute(Type type,
                               Field field,
                               boolean changingOverTime)

Method Detail

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 interface IModelTypeAttribute

Specified by:

isProductRelevant in class Attribute

Returns:

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

getValue

public Object getValue(IModelObject modelObject)

Description copied from class: PolicyAttribute

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

Specified by:

getValue in class PolicyAttribute

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

setValue

public void setValue(IModelObject modelObject,
                     Object value)

Description copied from class: PolicyAttribute

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

Specified by:

setValue in class PolicyAttribute

Parameters:

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

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

createOverwritingAttributeFor

public ConstantPolicyAttribute 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

getDefaultValue

public Object getDefaultValue(IConfigurableModelObject modelObject)

Description copied from class: PolicyAttribute

Returns the product configured default value of the attribute identified by this model type attribute. Throws an IllegalStateException 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.

Specified by:

getDefaultValue in class PolicyAttribute

Parameters:

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

See Also:

PolicyAttribute.getDefaultValue(IProductComponent, Calendar)

getDefaultValue

public Object getDefaultValue(IProductComponent source,
                              Calendar effectiveDate)

Description copied from class: PolicyAttribute

Returns the product configured default value of the attribute identified by this model type attribute.

Specified by:

getDefaultValue in class PolicyAttribute

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.

setDefaultValue

public void setDefaultValue(IConfigurableModelObject modelObject,
                            Object defaultValue)

Description copied from class: PolicyAttribute

Sets the product configured default value of the attribute identified by this model type attribute.

Specified by:

setDefaultValue in class PolicyAttribute

Parameters:

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

defaultValue - the new default value

setDefaultValue

public void setDefaultValue(IProductComponent source,
                            Calendar effectiveDate,
                            Object defaultValue)

Description copied from class: PolicyAttribute

Sets the product configured default value of the attribute identified by this model type attribute.

Specified by:

setDefaultValue in class PolicyAttribute

Parameters:

source - the product component to write the attribute default value 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.

defaultValue - the new default value

getValueSet

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

Description copied from class: PolicyAttribute

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

Note: If the PolicyCmptType this PolicyAttribute belongs to defines an UnrestrictedValueSet including null, no method is generated by Faktor-IPS. Therefore, a value set method in a subclass is not found even if the IModelObject passed to this method is an instance of that subclass. To make sure to get the correct value set, always use IpsModel.getPolicyCmptType(IModelObject) on the actual IModelObject instead of IpsModel.getPolicyCmptType(Class) on the super class.

Specified by:

getValueSet in class PolicyAttribute

Parameters:

modelObject - a model object

getValueSet

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

Description copied from class: PolicyAttribute

Returns the value set of the given model object's attribute identified by this model type attribute. Returns an UnrestrictedValueSet if there is no method that returns a value set for this attribute.

Specified by:

getValueSet in class PolicyAttribute

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.

setValueSet

public void setValueSet(IProductComponent source,
                        Calendar effectiveDate,
                        org.faktorips.valueset.ValueSet<?> valueSet)

Description copied from class: PolicyAttribute

Sets the product configured set of allowed values of the attribute identified by this model type attribute.

Caution: as generics are erased at runtime, it is possible to set a ValueSet of a mismatched type with this method, for example an OrderedValueSet<String> for an attribute with Attribute.getDatatype() Integer, which will result in a ClassCastException on later method calls.

Specified by:

setValueSet in class PolicyAttribute

Parameters:

source - the product component to write the attribute value set to. 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.

valueSet - the new value set

setValueSet

public void setValueSet(IConfigurableModelObject modelObject,
                        org.faktorips.valueset.ValueSet<?> valueSet)

Description copied from class: PolicyAttribute

Sets the product configured set of allowed values of the attribute identified by this model type attribute.

Caution: as generics are erased at runtime, it is possible to set a ValueSet of a mismatched type with this method, for example an OrderedValueSet<String> for an attribute with Attribute.getDatatype() Integer, which will result in a ClassCastException on later method calls.

Specified by:

setValueSet in class PolicyAttribute

Parameters:

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

valueSet - the new value set
