Null values, nil objects and collections

All constructors and setter methods accept null arguments. A null argument value means that the metadata element can not be provided, and the reason for that is unspecified. Alternatively, users can specify why a metadata element is missing by providing a value created by NilReason.createNilObject(Class).

Unless otherwise noted in the Javadoc, all getter methods may return an empty collection, an empty array or null if the type is neither a collection or an array. Note that non-null values may be NilObjects.

Unless the metadata object has been marked as unmodifiable and unless otherwise noted in the Javadoc, all collections returned by getter methods are live: adding new elements in the collection modify directly the underlying metadata object. Noticeable exceptions to this rule are union structures, for which only one property can be non-empty in the same object.
