All Implemented Interfaces:

FeatureBean, Serializable, Comparable<FeatureBean>

@Immutable
 @ParametersAreNonnullByDefault
public class ManyFeatureBean
extends AbstractFeatureBean

A simple representation of a multi-valued EStructuralFeature of a PersistentEObject. The "multi-valued" characteristic is identified with a position.

Constructor Detail

ManyFeatureBean

protected ManyFeatureBean(Id owner,
                          int id,
                          @Nonnegative
                          int position)

Constructs a new ManyFeatureBean with the given owner and the given id, which are used as a simple representation of a feature of an object. The "multi-valued" characteristic is identified with the position.

Parameters:

owner - the identifier of the object using the feature

id - the identifier of the feature of the owner

position - the position of the feature

Throws:

NullPointerException - if any argument is null

IllegalArgumentException - if the position is negative

Method Detail

from

@Nonnull
public static ManyFeatureBean from(org.eclipse.emf.ecore.InternalEObject owner,
                                             org.eclipse.emf.ecore.EStructuralFeature feature,
                                             @Nonnegative
                                             int position)

Creates a new ManyFeatureBean from the given owner and the given feature.

This method behaves like: from(PersistentEObject.from(owner), feature, position).

Parameters:

owner - the object that will be adapted to retrieve its identifier

feature - the feature of the owner from which the name will be extracted

position - the position of the feature

Returns:

a new ManyFeatureBean

Throws:

NullPointerException - if any argument is null

IllegalArgumentException - if the position is negative

@Nonnull
public static ManyFeatureBean from(PersistentEObject owner,
                                             org.eclipse.emf.ecore.EStructuralFeature feature,
                                             @Nonnegative
                                             int position)

Creates a new ManyFeatureBean from the given owner and the given feature.

This method behaves like: of(owner.id(), feature.getName(), position).

Parameters:

owner - the object from which the identifier will be extracted

feature - the feature of the owner from which the name will be extracted

position - the position of the feature

Returns:

a new ManyFeatureBean

Throws:

NullPointerException - if any argument is null

IllegalArgumentException - if the position is negative

                                           int position)

Creates a new ManyFeatureBean with the given owner and the given id, which are used as a simple representation of a feature of an object. The "multi-valued" characteristic is identified with the position.

Parameters:

owner - the identifier of the object

id - the identifier of the feature of the owner

position - the position of the feature

Returns:

a new ManyFeatureBean

Throws:

NullPointerException - if any argument is null

IllegalArgumentException - if the position is negative
