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 NilObject
s.
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.
