ConstraintOperator

public abstract 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.
protected int left_precedence

The precedence value used when the operator is about to be pushed to the stack.

protected int right_precedence

The precedence value used when the operator is on the top of the stack.

public object LeftContext { get; set; }

The syntax element preceding this operator

public virtual int LeftPrecedence { get; }

The precedence value used when the operator is about to be pushed to the stack.

public object RightContext { get; set; }

The syntax element folowing this operator

public virtual int RightPrecedence { get; }

The precedence value used when the operator is on the top of the stack.

protected ConstraintOperator()

public abstract void Reduce(ConstraintStack stack)

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.
