Method Detail

name

public String name()

Specified by:

name in class Operator<PhyPlanVisitor>

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.

getNextBoolean

public Result getNextBoolean()
                      throws ExecException

Specified by:

getNextBoolean in interface ComparisonOperator

Overrides:

getNextBoolean in class PhysicalOperator

Throws:

ExecException

clone

public NotEqualToExpr 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

Do not use the clone method directly. Operators are cloned when logical plans are cloned using {@link LogicalPlanCloner}
