TargetedSegmentListFunction Class

A SolvableMultivariableFunction that can be used in a MultivariableFunctionSolver to solve for an arbitrary trajectory or other state elements based on variables and constraints.

This function will be created automatically at propagation time inside any TargetedSegmentListOperator that requires a function. As such, this will not dispose the items it is configured with.

The TargetedSegmentListFunction type exposes the following members.

Constructors

	Name	Description
	TargetedSegmentListFunction(TargetedSegmentListFunction, CopyContext)	Initializes a new instance as a copy of an existing instance.
	TargetedSegmentListFunction(IListSegmentPropagatorVariableEvaluator, IListSegmentPropagatorConstraintEvaluator, IListSegmentPropagator, FiniteDifferenceMethod, TargetedSegmentListResults, TargetedSegmentListConfiguration)	Initializes a new instance. The items passed in can be the original items that would be propagated normally; you do not need to clone or otherwise copy the parameters for this function.

Properties

	Name	Description
	DifferenceMethod	Gets or sets how the default numerically computed derivative of this function should be computed. (Inherited from SolvableMultivariableFunction.)
	IsThreadSafe	Gets a value indicating whether the methods on this instance are safe to call from multiple threads simultaneously. (Overrides SolvableMultivariableFunctionIsThreadSafe.)
	PerturbationValues	Gets or sets the values to use to perturb the variables when the derivative is computed numerically. This can be ignored if the concrete function computes its derivative analytically. (Inherited from SolvableMultivariableFunction.)

Methods

	Name	Description
	ApplyResults	For SolvableMultivariableFunctions that have state, there may be times when that state should be manually set on a function (sometimes for performance reasons, when the function will be called multiple times and it should start from where it left off). This method will manually set that state, if needed. (Overrides SolvableMultivariableFunctionApplyResults(SolvableMultivariableFunctionResults).)
	CallDerivativeEvaluationEvent	Calls the DerivativeEvaluationEvent. (Inherited from SolvableMultivariableFunction.)
	Clone	Clones this object using the specified context. (Overrides SolvableMultivariableFunctionClone(CopyContext).)
	Dispose	Releases any resources associated with this instance. (Inherited from SolvableMultivariableFunction.)
	Dispose(Boolean)	Releases any resources associated with this instance. (Inherited from SolvableMultivariableFunction.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Evaluate(Double, ITrackCalculationProgress)	Evaluates the function. The SolvableMultivariableFunctionResults returned must include the computed constraints in the order that they are in the Constraints. If your function computes more than just constraint values you should extend SolvableMultivariableFunctionResults to contain those additional results. (Overrides SolvableMultivariableFunctionEvaluate(Double, ITrackCalculationProgress).)
	Evaluate(Double, Int32, Boolean, ITrackCalculationProgress)	Evaluates the function and the Jacobian. This will call both the DerivativeEvaluationEvent and the NormalFunctionEvaluationEvent events. (Inherited from SolvableMultivariableFunction.)
	EvaluateDerivative(Double, Boolean, ITrackCalculationProgress)	Evaluates the Jacobian of this function. The default implementation of this method will numerically compute the Jacobian. To do that, the value of the function at the variables will be computed. When using the default implementation, the PerturbationValues must be set. (Inherited from SolvableMultivariableFunction.)
	EvaluateDerivative(Double, Boolean, SolvableMultivariableFunctionResults, ITrackCalculationProgress)	Evaluates the Jacobian of this function. The default implementation of this method will numerically compute the Jacobian. To do that, the value of the function at the variables will be computed. (Inherited from SolvableMultivariableFunction.)
	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.)

Events

	Name	Description
	DerivativeEvaluationEvent	An event that gets raised when the derivative of the function is evaluated. This event will be raised in whatever thread the derivative is evaluated in. If you override the EvaluateDerivative(Double, Boolean, SolvableMultivariableFunctionResults, ITrackCalculationProgress) method, you should call this event. (Inherited from SolvableMultivariableFunction.)
	NormalFunctionEvaluationEvent	An event that gets raised when the nominal function is evaluated. This event will be raised in whatever thread the nominal function run was. This should be called in the concrete Evaluate(Double, ITrackCalculationProgress) method. (Inherited from SolvableMultivariableFunction.)
	PerturbedFunctionEvaluationEvent	An event that gets raised when a perturbed function is computed as part of the derivation of the derivative of the function. This event will be raised in whatever thread the function was evaluated in. This can be ignored if the concrete function computes its derivative analytically. (Inherited from SolvableMultivariableFunction.)

Remarks

This function applies and resets the variable values supplied by the MultivariableFunctionDifferentialSolver.
