public interface StructuralFeature
extends Feature

A structural feature refers to a static feature of a model element. In the metamodel, a StructuralFeature declares a structural aspect of a Classifier that is typed, such as an attribute. For example, it specifies the multiplicity and changeability of the StructuralFeature. StructuralFeature is an abstract metaclass.

Method Detail

getChangeability

public ChangeableKind getChangeability()
                                throws javax.jmi.reflect.JmiException
Specifies whether the value may be modified after the object is created.

setChangeability

public void setChangeability(ChangeableKind newValue)
                      throws javax.jmi.reflect.JmiException
Specifies whether the value may be modified after the object is created.

getMultiplicity

public Multiplicity getMultiplicity()
                             throws javax.jmi.reflect.JmiException
The possible number of data values for the feature that may be held by an instance. The cardinality of the set of values is an implicit part of the feature. In the common case in which the multiplicity is 1..1, then the feature is a scalar (i.e., it holds exactly one value).

setMultiplicity

public void setMultiplicity(Multiplicity newValue)
                     throws javax.jmi.reflect.JmiException
The possible number of data values for the feature that may be held by an instance. The cardinality of the set of values is an implicit part of the feature. In the common case in which the multiplicity is 1..1, then the feature is a scalar (i.e., it holds exactly one value).

getOrdering

public OrderingKind getOrdering()
                         throws javax.jmi.reflect.JmiException
Specifies whether the set of instances is ordered. The ordering must be determined and maintained by Operations that add values to the feature. This property is only relevant if the multiplicity is greater than one.

setOrdering

public void setOrdering(OrderingKind newValue)
                 throws javax.jmi.reflect.JmiException
Specifies whether the set of instances is ordered. The ordering must be determined and maintained by Operations that add values to the feature. This property is only relevant if the multiplicity is greater than one.

getTargetScope

public ScopeKind getTargetScope()
                         throws javax.jmi.reflect.JmiException
Specifies whether the targets are ordinary Instances or are Classifiers.

setTargetScope

public void setTargetScope(ScopeKind newValue)
                    throws javax.jmi.reflect.JmiException
Specifies whether the targets are ordinary Instances or are Classifiers.

getType

public Classifier getType()
                   throws javax.jmi.reflect.JmiException

setType

public void setType(Classifier newValue)
             throws javax.jmi.reflect.JmiException
