Class ConstraintOperator

Namespace

NUnit.Framework.Constraints

Assembly

nunit.framework.dll

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.

Fields

left_precedence

Properties

LeftContext

The syntax element preceding this operator

public object? LeftContext { get; set; }

Property Value

object

LeftPrecedence

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

public virtual int LeftPrecedence { get; }

Property Value

int

RightContext

The syntax element following this operator

public object? RightContext { get; set; }

Property Value

public virtual int RightPrecedence { get; }

Property Value

int

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.

public abstract void Reduce(ConstraintBuilder.ConstraintStack stack)

Parameters

stack ConstraintBuilder.ConstraintStack
