public abstract class LazyObjectiveFunctionBase : IObjectiveFunction, IObjectiveFunctionEvaluation
The LazyObjectiveFunctionBase type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | LazyObjectiveFunctionBase | Initializes a new instance of the LazyObjectiveFunctionBase class. |
Properties| Name | Description | |
|---|---|---|
 | FunctionValue | Gets or sets the cached function value. |
 | Gradient | Gets the gradient at Point. |
| GradientValue | Gets or sets the cached gradient. |
| HasFunctionValue | Gets or sets a value indicating whether the function value is available. |
| HasGradientValue | Gets or sets a value indicating whether the gradient is available. |
| HasHessianValue | Gets or sets a value indicating whether the Hessian is available. |
| Hessian | Gets the Hessian matrix at Point. |
| HessianValue | Gets or sets the cached Hessian. |
| IsGradientSupported | Gets a value indicating whether gradient information is available. |
| IsHessianSupported | Gets a value indicating whether Hessian information is available. |
| Point | Gets the point at which the objective function is currently evaluated. |
| Value | Gets the objective function value at Point. |
Methods| Name | Description | |
|---|---|---|
 | CreateNew | Creates a new unevaluated and independent copy of this objective function. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| EvaluateAt | Evaluates the objective function at the specified point. |
| EvaluateGradient | Evaluates the gradient. |
| EvaluateHessian | Evaluates the Hessian. |
| EvaluateValue | Evaluates the function value. |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| Fork | Creates a new independent copy of this objective function, evaluated at the same point. |
| 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) |
