Constructor Detail

ModExpression

public ModExpression(OperatorPlan plan,
                     byte b,
                     LogicalExpression lhs,
                     LogicalExpression rhs)
Will add this operator to the plan and connect it to the left and right hand side operators.

Parameters:
plan - plan this operator is part of
b - this is the type of this expression
lhs - expression on its left hand side
rhs - expression on its right hand side
Method Detail

accept

public void accept(PlanVisitor v)
            throws IOException
Description copied from class: Operator
Accept a visitor at this node in the graph.

Specified by:
accept in class Operator
Parameters:
v - Visitor to accept.
Throws:
IOException

isEqual

public boolean isEqual(Operator other)
Description copied from class: Operator
This is like a shallow equals comparison. It returns true if two operators have equivalent properties even if they are different objects. Here properties mean equivalent plan and equivalent name.

Specified by:
isEqual in class Operator
Returns:
true if two object have equivalent properties, else false
