- 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.
