com.hp.hpl.jena.rdf.model.RDFList.concatenate()

Change the tail of this list to point to the given list, so that this list becomes the list of the concatenation of the elements of both lists. This is a side-effecting operation on this list; for a non side-effecting alternative, see {@link #append}. Due to the problem of maintaining the URI invariant on a node, this operation will throw an exception if an attempt is made to concatenate onto an empty list. To avoid this, test for an empty list: if true replace the empty list with the argument list, otherwise proceed with the concatenate as usual. An alternative solution is to use {@link #append} and replace the original list with the return value.

@param list The argument list to concatenate to this list @exception EmptyListUpdateException if this list is the nil list

    final int listLen = list.size();


    // now append foos to the root list
    final RDFList root = getListRoot(model);
    final int rootLen = root.size();
    root.concatenate(list);


    // original list should be unchanged
    checkValid("concatTest0", list, true);
    Assert.assertEquals("Original list should be unchanged", listLen,
        list.size());

    else
    {
      final RDFList copy = copy();
      if (list.size() > 0)
      {
        copy.concatenate(list.copy());
      }
      return copy;
    }
