Constructor Detail

AbstractFeatureBean

protected AbstractFeatureBean(Id owner,
                              int id)

Constructs a new AbstractFeatureBean with the given owner and the given id.

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

AbstractFeatureBean

protected AbstractFeatureBean(Id owner,
                              int id,
                              int position)

Constructs a new ManyFeatureBean 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:

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 when isMany() == true
