The NonlinearConstraint type exposes the following members.

	Name	Description
	ConstraintFunction	Gets or sets the constraint function.
	ConstraintFunctionAndGradient	Gets or sets a delegate that evaluates the constraint value and its gradient.
	ConstraintType	Gets the type of row. (Inherited from Constraint.)
	FastConstraintGradient	Gets or sets the gradient of the constraint function.
	Gradient	Gets the current value of the constraint gradient. (Inherited from Constraint.)
	IsLinear	Gets whether the constraint is linear. (Overrides ConstraintIsLinear.)
	LowerBound	Gets or sets the lower bound of the variable. (Inherited from OptimizationModelEntity.)
	Name	Gets the name of the variable. (Inherited from OptimizationModelEntity.)
	Position	Gets the position of the current instance in the collection. (Inherited from OptimizationModelEntity.)
	UpperBound	Gets or sets the upper bound of the variable. (Inherited from OptimizationModelEntity.)
	Value	Gets the current value of the constraint. (Inherited from Constraint.)

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Evaluate	Evaluates the constraint at the specified point. (Overrides ConstraintEvaluate(VectorDouble).)
	EvaluateConstraintAndGradient	Evaluates both the constrain value and its gradient in one operation. (Overrides ConstraintEvaluateConstraintAndGradient(VectorDouble).)
	EvaluateGradient	Evaluates the gradient of the constraint at the specified point. (Overrides ConstraintEvaluateGradient(VectorDouble).)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

A NonlinearConstraint object represents a constraint in a NonlinearProgram. NonlinearConstraint objects are created using the [o:NonlinearProgram.AddNonlinearConstraint] method of the NonlinearProgram class.

Each constraint has a Name, which may be generated automatically. The LowerBound and UpperBound properties specify the left and right hand sides of the constraint. The ConstraintFunction property specifies the function whose value must lie between those bounds.

The FastConstraintGradient property specifies the gradient of the constraint function. If this value is , a numerical approximation is used.
