    Description copied from interface: TraverserVisitor
    
    This method is called when a node was already visited before. This can happen for two reasons: 1. There is a cycle. 2. A node has more than one parent. This means the structure is not a tree but a graph.
    
    Specified by:
    
    backRef in interface TraverserVisitor<GraphQLSchemaElement>
    
    Parameters:
    
    context - the context in place
    
    Returns:
    
    Only Continue or Quit allowed
