Property interface

A Property is a StructuralFeature. A Property related by ownedAttribute to a Classifier (other than an association) represents an attribute and might also represent an association end. It relates an instance of the Classifier to a value or set of values of the type of the attribute. A Property related by memberEnd to an Association represents an end of the Association. The type of the Property is the type of the end of the Association.

Attributes

NameTypeDescription
aggregationAggregationKind [1..1] 
appliedStereotypesStereotype [0..*]Indicates which stereotypes from the selected profile (or profiles) are applied to the element. The selected profiles are the profiles that are applied to the containing package. Inherited from Element.
associationAssociation [0..1]The Association of which this Property is a member, if any. 
defaultValueValueSpecification [0..1]A ValueSpecification that is evaluated to give a default value for the Property when an instance of the owning Classifier is instantiated. 
idstring Gets the unique ID of the element. Inherited from Element.
isDerivedboolean Specifies whether the property is derived as the union of all of the Properties that are constrained to subset it. 
isDerivedUnionboolean Specifies whether the property is derived as the union of all of the Properties that are constrained to subset it. 
isIDboolean True indicates this property can be used to uniquely identify an instance of the containing Class. 
isLeafboolean Indicates whether it is possible to further redefine a RedefinableElement. If the value is true, then it is not possible to further redefine the RedefinableElement. Inherited from RedefinableElement.
isNavigableboolean [1..1]Returns true if the Property is owned by a classifier or is included in the NavigableOwnedEnds of an association. 
isOrderedboolean For a multivalued multiplicity, this attribute specifies whether the values in an instantiation of this MultiplicityElement are sequentially ordered. Inherited from MultiplicityElement.
isReadOnlyboolean If isReadOnly is true, the StructuralFeature may not be written to after initialization. Inherited from StructuralFeature.
isStaticboolean Specifies whether this Feature characterizes individual instances classified by the Classifier (false) or the Classifier itself (true). Inherited from Feature.
isUniqueboolean For a multivalued multiplicity, this attributes specifies whether the values in an instantiation of this MultiplicityElement are unique. Inherited from MultiplicityElement.
lowerinteger [0..1]Gets the lower bound of the multiplicity interval. Inherited from MultiplicityElement.
lowerValueValueSpecification [0..1]The specification of the lower bound for this multiplicity. Inherited from MultiplicityElement.
namestring The name of the NamedElement. Inherited from NamedElement.
orderinteger [1..1]Gets or set the sort order of the element if it is part of a collection. The value is 0 for elements to which no particular ordering applies. Elements with a lower order come before elements with a higher order. Inherited from OrderedElement.
ownedCommentsComment [0..*]The Comments owned by this Element. Inherited from Element.
ownerElement [0..1]Gets the element that owns this element. Inherited from Element.
taggedValuesTaggedValueSpecification [0..*]Contains 0 or more tagged values for the element. Inherited from Element.
typeType [0..1]The type of the TypedElement. Inherited from TypedElement.
upperUnlimitedNatural [0..1]The upper bound of the multiplicity interval. Inherited from MultiplicityElement.
upperValueValueSpecification [0..1]The specification of the upper bound for this multiplicity. Inherited from MultiplicityElement.
visibilityVisibilityKind [0..1]Determines whether and how the NamedElement is visible outside its owning Namespace. Inherited from NamedElement.

Operations

NameReturnsDescription
getDefault()

Property.getDefault

X

Gets the value of the DefaultValue property.

Return value
Type: object [0..1]
The default value (the type depending on the type of value), or null if no default value can be determined.
object [0..1]Gets the value of the DefaultValue property. 
getFirstCommentBody()

Property.getFirstCommentBody

X

Gets the text contents of the first comment in the element's owned comments, or an empty string if the element has no comments.

Return value
Type: string [1..1]
The body string of the first comment. If the element has no comments, an empty string is returned.
string [1..1]Gets the text contents of the first comment in the element's owned comments, or an empty string if the element has no comments. Inherited from Element.
getLowerBound()

Property.getLowerBound

X

The query lowerBound() returns the lower bound of the multiplicity as an integer, which is the integerValue of lowerValue, if this is given, and 1 otherwise.

Return value
