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
  NameDescription
Public propertyAvailabilityIntervals
Gets a TimeIntervalCollection over which data is available. If the availability interval is infinite, this returns Infinite.
(Inherited from MotionEvaluatorT.)
Public propertyDefinedInIntervals
Gets a TimeIntervalCollection where the Data property of each interval is the ReferenceFrame in which this Point is defined over the interval.
Public propertyGroup
Gets the group that contains this evaluator.
(Inherited from MotionEvaluatorT.)
Public propertyIsThreadSafe
Gets a value indicating if the methods on this instance are safe to call from multiple threads simultaneously.
(Inherited from FunctionTIndependent, TDependent.)
Public propertyIsTimeVarying
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
  NameDescription
Public methodClone
Clones this object using the specified context.
(Inherited from FunctionTIndependent, TDependent.)
Protected methodStatic memberCreateConstantDefinedIn
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.
Public methodDispose
Releases any resources associated with this instance.
(Inherited from FunctionTIndependent, TDependent.)
Protected methodDispose(Boolean)
Releases any resources associated with this instance.
(Inherited from FunctionTIndependent, TDependent.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Public methodEvaluate(JulianDate)
Evaluates the function.
(Inherited from MotionEvaluatorT.)
Public methodEvaluate(JulianDate, Int32)
Evaluates the function.
(Inherited from MotionEvaluatorT.)
Public methodEvaluate(TimeInterval, Duration, Int32)
Evaluates this evaluator at a specified fixed step over the specified interval.
(Inherited from MotionEvaluatorT.)
Public methodEvaluate(JulianDate, JulianDate, Duration, Int32)
Evaluates this evaluator at a specified fixed step over the specified interval.
(Inherited from MotionEvaluatorT.)
Public methodEvaluate(TimeInterval, Duration, Int32, ITrackCalculationProgress)
Evaluates this evaluator at a specified fixed step over the specified interval.
(Inherited from MotionEvaluatorT.)
Public methodEvaluate(JulianDate, JulianDate, Duration, Int32, ITrackCalculationProgress)
Evaluates this evaluator at a specified fixed step over the specified interval.
(Inherited from MotionEvaluatorT.)
Protected methodEvaluateMotionWithoutOrder
Evaluates the function using a default order.
(Inherited from MotionEvaluatorT.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetAvailabilityIntervals
Gets the intervals over which data is available. If the availability interval is infinite, this returns Infinite.
(Inherited from MotionEvaluatorT.)
Public methodGetCachingWrapper
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.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetNextSampleSuggestion
Gets a suggestion for the next independent variable value at which to sample this function.
(Inherited from FunctionTIndependent, TDependent.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodIsAvailable
Returns if valid data is available for this Julian date, otherwise returns .
(Inherited from MotionEvaluatorT.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodSimplifyIfNotTimeVarying
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.
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
Public methodUpdateEvaluatorReferences
Updates the evaluator references held by this object using the reference-to-reference mapping in the specified CopyContext.
(Inherited from MotionEvaluatorT.)
