Parameters:

owner - the identifier of the object using the feature

id - the identifier of the feature of the owner

Throws:

NullPointerException - if any argument is null

public static SingleFeatureBean from(org.eclipse.emf.ecore.InternalEObject owner,
                                               org.eclipse.emf.ecore.EStructuralFeature feature)

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

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

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

Returns:

a new SingleFeatureBean

Throws:

NullPointerException - if any argument is null

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

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

Parameters:

owner - the object from which the identifier will be extracted

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

Returns:

a new SingleFeatureBean

Throws:

Creates a new SingleFeatureBean with the given owner and the given id, which are used as a simple representation of a feature of an object.

Parameters:

owner - the identifier of the object

id - the identifier of the feature of the owner

Returns:

a new SingleFeatureBean

Throws:

NullPointerException - if any argument is null
