PointEvaluator Class

Evaluates a Point over time.

The result of evaluating will be a Motion<Cartesian> representation of this point at the specified JulianDate. This evaluator will attempt to provide derivatives of the position up to the requested order.

Properties

	Name	Description
	AvailabilityIntervals	Gets a TimeIntervalCollection over which data is available. If the availability interval is infinite, this returns Infinite. (Inherited from MotionEvaluatorT.)
	DefinedInIntervals	Gets a TimeIntervalCollection where the Data property of each interval is the ReferenceFrame in which this Point is defined over the interval.
	Group	Gets the group that contains this evaluator. (Inherited from MotionEvaluatorT.)
	IsThreadSafe	Gets a value indicating whether the methods on this instance are safe to call from multiple threads simultaneously. (Inherited from FunctionTIndependent, TDependent.)
	IsTimeVarying	Gets a value indicating whether or not the value of this evaluator changes with time. If , the evaluator is assumed to return the same value for any input JulianDate. (Inherited from MotionEvaluatorT.)

Methods

	Name	Description
	Clone	Clones this object using the specified context. (Inherited from FunctionTIndependent, TDependent.)
	CreateConstantDefinedIn	Creates a TimeIntervalCollection indicating that the ReferenceFrame that this Point is defined in is the same for all possible times. This is useful for constructing the value of the DefinedInIntervals property.
	Dispose	Releases any resources associated with this instance. (Inherited from FunctionTIndependent, TDependent.)
	Dispose(Boolean)	Releases any resources associated with this instance. (Inherited from FunctionTIndependent, TDependent.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Evaluate(JulianDate)	Evaluates the function. (Inherited from MotionEvaluatorT.)
	Evaluate(JulianDate, Int32)	Evaluates the function. (Inherited from MotionEvaluatorT.)
	Evaluate(TimeInterval, Duration, Int32)	Evaluates this evaluator at a specified fixed step over the specified interval. (Inherited from MotionEvaluatorT.)
	Evaluate(JulianDate, JulianDate, Duration, Int32)	Evaluates this evaluator at a specified fixed step over the specified interval. (Inherited from MotionEvaluatorT.)
	Evaluate(TimeInterval, Duration, Int32, ITrackCalculationProgress)	Evaluates this evaluator at a specified fixed step over the specified interval. (Inherited from MotionEvaluatorT.)
	Evaluate(JulianDate, JulianDate, Duration, Int32, ITrackCalculationProgress)	Evaluates this evaluator at a specified fixed step over the specified interval. (Inherited from MotionEvaluatorT.)
	EvaluateMotionWithoutOrder	Evaluates the function using a default order. (Inherited from MotionEvaluatorT.)
	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. (Inherited from MotionEvaluatorT.)
	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. (Overrides MotionEvaluatorTGetCachingWrapper.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetNextSampleSuggestion	Gets a suggestion for the next independent variable value at which to sample this function. (Inherited from FunctionTIndependent, TDependent.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsAvailable	Determines if valid data is available for the given JulianDate. (Inherited from MotionEvaluatorT.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SimplifyIfNotTimeVarying	If this evaluator is not time varying, this method evaluates its value and constructs an evaluator from a PointFixedOffset representing the fixed value. If this evaluator is time varying, this method does nothing and returns the evaluator on which it is called.
	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. (Inherited from MotionEvaluatorT.)
