Examples of EmptyListUpdateException

com.hp.hpl.jena.rdf.model.EmptyListUpdateException

Exception that is thrown when an attept is made to perform a side-effectful operation on an {@link 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 {@link RDFList#cons}, or {@link RDFList#with}, or check first to see if the list {@linkplain RDFList#isEmpty is empty}, and replace it with a non-null list.

    {
      // concatenating list onto the empty list is an error
      throw new EmptyListUpdateException(
          "Tried to concatenate onto the empty list");
    }
    else

      final org.apache.jena.security.SecurityEvaluator.SecNode p = SecuredItemImpl
