SegmentPropagatorCostFunctionEvaluator Class

The evaluator for SegmentPropagatorCostFunction used in a ParameterOptimizer. Instances of this type return some value computed from the SegmentListResults of all the results of propagation up to the end of the final segment in the SegmentListPropagator that has the ParameterOptimizer that has this cost function.

The SegmentPropagatorCostFunctionEvaluator type exposes the following members.

Constructors

	Name	Description
	SegmentPropagatorCostFunctionEvaluator(EvaluatorGroup, SegmentPropagatorCostFunction)	Initializes a new instance.
	SegmentPropagatorCostFunctionEvaluator(SegmentPropagatorCostFunctionEvaluator, CopyContext)	Initializes a new instance as a copy of an existing instance.

Properties

	Name	Description
	Group	Gets the group that contains this evaluator.
	Identifier	Gets the identifier for this evaluator. It is highly discouraged to use this for anything other than identification purposes.
	IsThreadSafe	Gets a value indicating whether the methods on this instance are safe to call from multiple threads simultaneously.
	Name	Gets the optional name of this cost function evaluator.

Methods

	Name	Description
	Clone	Clones this object using the specified context.
	CreateSettings	Creates the CostFunctionSettings for use with a ParameterOptimizer.
	Dispose	Releases any resources associated with this instance.
	Dispose(Boolean)	Releases any resources associated with this instance.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Evaluate	Extracts or computes a value from the results for the entire propagation up through the final segment in the parent SegmentList.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetAvailabilityIntervals	Gets the intervals over which data is available.
	GetCachingWrapper	Gets a version of this evaluator that caches the previously computed value so that if it is evaluated twice at the same date the computation is done only once.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsAvailable	Determines if valid data is available for the given JulianDate.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	UpdateEvaluatorReferences	Updates the evaluator references held by this object using the reference-to-reference mapping in the specified CopyContext.

Remarks

Be aware that concrete types of this can pull results from any or all of the SegmentListResults passed into it; this base type does not limit you to just obtaining results from a single SegmentPropagator. If your concrete type is meant to work with SegmentResults from a single segment, your constraint evaluator should store a reference to the SegmentDefinition and call GetResultsOfSegment(SegmentDefinition).
