- java.lang.Throwable
- - java.lang.Exception
  - - java.lang.RuntimeException
    - - org.apache.jena.shared.JenaException
      - org.apache.jena.rdf.model.EmptyListUpdateException

All Implemented Interfaces:

java.io.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(org.apache.jena.rdf.model.RDFNode), or RDFList.with(org.apache.jena.rdf.model.RDFNode), or check first to see if the list is empty, and replace it with a non-null list.
