- All Implemented Interfaces:
- Serializable
public class EmptyListUpdateException
- extends JenaException
Exception that is thrown when an attept is made to perform a side-effectful
operation on an RDFList
that is the empty list, or rdf:nil
.
This is not permissible, since it would cause the URI of the RDFList to change
from rdf:nil
to a new bNode, and in Jena the URI of a node is
invariant. To avoid this operation, when extending an empty list use operations
that return the updated list (such as RDFList.cons(com.hp.hpl.jena.rdf.model.RDFNode)
, or RDFList.with(com.hp.hpl.jena.rdf.model.RDFNode)
,
or check first to see if the list is empty, and replace
it with a non-null list.
