                                                   throws X extends Exception

      Description copied from class: `AbstractQueryModelNode`
      Dummy implementation of `QueryModelNode.visitChildren(org.eclipse.rdf4j.query.algebra.QueryModelVisitor<X>)` that does nothing. Subclasses should override this method when they have child nodes.
      Specified by:
        `visitChildren` in interface `QueryModelNode`
      Overrides:
        `visitChildren` in class `AbstractQueryModelNode`
      Throws:
        `X extends Exception`

    - #### equals

          public boolean equals(Object other)

      Description copied from interface: `QueryModelNode`
      Returns `true` if this query model node and its children are recursively equal to `o` and its children.
      Specified by:
        `equals` in interface `QueryModelNode`
      Overrides:
        `equals` in class `Object`

    - #### hashCode

          public int hashCode()

      Overrides:
        `hashCode` in class `Object`

    - #### clone

          public ValueExprTripleRef clone()

      Description copied from interface: `QueryModelNode`
      Returns a (deep) clone of this query model node. This method recursively clones the entire node tree, starting from this nodes.
      Specified by:
        `clone` in interface `QueryModelNode`
      Specified by:
        `clone` in interface `ValueExpr`
      Overrides:
        `clone` in class `AbstractQueryModelNode`
      Returns:
        A deep clone of this query model node.

    - #### visit

          public <X extends Exception> void visit(QueryModelVisitor<X> visitor)
                                           throws X extends Exception

      Description copied from interface: `QueryModelNode`
      Visits this node. The node reports itself to the visitor with the proper runtime type.
      Specified by:
        `visit` in interface `QueryModelNode`
      Throws:
        `X extends Exception`
