                  ExpressionOperator input)
Method Detail

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.

name

public String name()
Specified by:
name in class Operator<PhyPlanVisitor>

getNext

public Result getNext(Double d)
               throws ExecException
Overrides:
getNext in class PhysicalOperator
Throws:
ExecException

getNext

public Result getNext(Float f)
               throws ExecException
Overrides:
getNext in class PhysicalOperator
Throws:
ExecException

getNext

public Result getNext(Integer i)
               throws ExecException
Overrides:
getNext in class PhysicalOperator
Throws:
ExecException

getNext

public Result getNext(Long l)
               throws ExecException
Overrides:
getNext in class PhysicalOperator
Throws:
ExecException

clone

public PONegative 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}

illustratorMarkup

public Tuple illustratorMarkup(Object in,
                               Object out,
                               int eqClassIndex)
Description copied from interface: Illustrable
input tuple mark up to be illustrate-able

Parameters:
in - input tuple
out - output tuple before wrapped in ExampleTuple
eqClassIndex - index into equivalence classes in illustrator
Returns:
tuple
