Class ConstraintOperator

The ConstraintOperator class is used internally by a ConstraintBuilder to represent an operator that modifies or combines constraints.

Constraint operators use left and right precedence values to determine whether the top operator on the stack should be reduced before pushing a new operator.

Methods

Reduce(ConstraintStack)

Reduce produces a constraint from the operator and any arguments. It takes the arguments from the constraint stack and pushes the resulting constraint on it.

Declaration

public abstract void Reduce(ConstraintBuilder.ConstraintStack stack)
