    transform(org.apache.jena.sparql.algebra.op.OpDistinct op, org.apache.jena.sparql.algebra.Op subOp)
    Distinct has implications in up (towards parent) and down (towards children) directions of the tree: upwards: the current set of projected variables is distinct downwards: substituting the currently visible variables with an expression where they are distinct would be valid.

      public org.apache.jena.sparql.algebra.Op transform(org.apache.jena.sparql.algebra.op.OpDistinct op, org.apache.jena.sparql.algebra.Op subOp)
      Distinct has implications in up (towards parent) and down (towards children) directions of the tree: upwards: the current set of projected variables is distinct downwards: substituting the currently visible variables with an expression where they are distinct would be valid. Hence, we can propagate the information that the visible variables are allowed to be distinct.
