Constructor Detail

Attribute

public Attribute(Type type,
                 IpsAttribute attributeAnnotation,
                 IpsExtensionProperties extensionProperties,
                 java.lang.Class<?> datatype,
                 boolean changingOverTime)

Method Detail

isChangingOverTime

public boolean isChangingOverTime()

Returns true if this attribute is changing over time. For product attribute that means the attribute resides in the generation. For policy attributes the optional product configuration resides in the generation.

Returns:

true if the attribute is changing over time, false if not

isProductRelevant

public abstract boolean isProductRelevant()

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

Returns:

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

getDatatype

public java.lang.Class<?> getDatatype()

Returns the data type of this attribute.

Returns:

the attribute's datatype Class

getAttributeKind

public AttributeKind getAttributeKind()

Returns the possible kinds of this attribute.

Returns:

the kind of attribute

getValueSetKind

public ValueSetKind getValueSetKind()

Returns the ValueSetKind of this attribute.

Returns:

the kind of value set restricting this attribute

isOverriding

public boolean isOverriding()

Returns true if this attribute overrides another attribute. That means a supertype declares an attribute with the same name.

Returns:

true if this attribute overrides another, false if not

See Also:

getSuperAttribute()

getSuperAttribute

public Attribute getSuperAttribute()

Returns the attribute that is overridden by this attribute if this attribute overrides another one. Otherwise returns null.

Returns:

The attribute that is overridden by this attribute.

See Also:

isOverriding()

findSuperAttribute

public java.util.Optional<Attribute> findSuperAttribute()

Returns the attribute that is overridden by this attribute if this attribute overrides another one. Otherwise returns null.

Returns:

The attribute that is overridden by this attribute.

See Also:

isOverriding()

toString

public java.lang.String toString()

Overrides:

toString in class ModelElement

createOverwritingAttributeFor

public abstract Attribute createOverwritingAttributeFor(Type subType)

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.

Parameters:

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

Returns:

a Attribute for the given sub model type

getRelevantProductObject

protected java.lang.Object getRelevantProductObject(IProductComponent productComponent,
                                                    java.util.Calendar effectiveDate)
