    Description copied from interface: RelNode
    
    Creates a copy of this relational expression, perhaps changing traits and inputs.
    Sub-classes with other important attributes are encouraged to create variants of this method with more parameters.
    
    Specified by:
    
    copy in interface RelNode
    
    Overrides:
    
    copy in class AbstractRelNode
    
    Parameters:
    
    traitSet - Trait set
    
    inputs - Inputs
    
    Returns:
    
    Copy of this relational expression, substituting traits and inputs
  - implement
