MultivaluedFeatureKey

protected MultivaluedFeatureKey(@Nonnull
                                Id id,
                                @Nonnull
                                String name,

                                int position)

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

Parameters:

id - the identifier of the PersistentEObject

name - the name of the EStructuralFeature of the PersistentEObject

position - the position of the EStructuralFeature

from

public static MultivaluedFeatureKey from(@Nonnull
                                         InternalEObject internalObject,
                                         @Nonnull
                                         EStructuralFeature feature,
                                         @Nonnegative
                                         int position)

Creates a new MultivaluedFeatureKey from the given internalObject and the given feature.

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

Parameters:

internalObject - the InternalEObject that will be adapted as PersistentEObject to have its identifier

feature - the EStructuralFeature of the PersistentEObject from which the name will be extracted

position - the position of the EStructuralFeature

Returns:

a new MultivaluedFeatureKey

public static MultivaluedFeatureKey from(@Nonnull
                                         PersistentEObject object,
                                         @Nonnull
                                         EStructuralFeature feature,

                                         int position)

Creates a new MultivaluedFeatureKey from the given object and the given feature.

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

Parameters:

object - the PersistentEObject from which the identifier will be extracted

feature - the EStructuralFeature of the PersistentEObject from which the name will be extracted

position - the position of the EStructuralFeature

Returns:

a new MultivaluedFeatureKey

                                       int position)

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

Parameters:

id - the identifier of the PersistentEObject

name - the name of the EStructuralFeature of the PersistentEObject

position - the position of the EStructuralFeature

Returns:

a new MultivaluedFeatureKey
