visit
public void visit(PhyPlanVisitor v)
throws VisitorException
- Description copied from class:
Operator
- Visit this node with the provided visitor. This should only be called by
the visitor class itself, never directly.
- Specified by:
visit
in class ExpressionOperator
- Parameters:
v
- Visitor to visit with.
- Throws:
VisitorException
- if the visitor has a problem.

clone
public Divide clone()
throws CloneNotSupportedException
- Description copied from class:
ExpressionOperator
- Make a deep copy of this operator. This is declared here to make it
possible to call clone on ExpressionOperators.
- Overrides:
clone
in class ExpressionOperator
- Throws:
CloneNotSupportedException
- See Also:
Do not use the clone method directly. Operators are cloned when logical plans
are cloned using {@link LogicalPlanCloner}
