J4Propagator Methods |
The J4Propagator type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | CheckForSameDefinition(CartesianOnePointPropagator) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Overrides CartesianOnePointPropagatorCheckForSameDefinition(CartesianOnePointPropagator).) |
| CheckForSameDefinition(DefinitionalObject) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Inherited from CartesianOnePointPropagator.) |
| CheckForSameDefinition(J4Propagator) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
|
 | Clone |
Clones this object using the specified context.
(Overrides DefinitionalObjectClone(CopyContext).) |
| ComputeCurrentDefinitionHashCode |
Computes a hash code based on the current properties of this object. Derived classes MUST override this
method and compute a hash code that combines: a unique hash code seed, the base implementation result, and
the hash codes of all new fields introduced by the derived class which are used in the
CheckForSameDefinition(DefinitionalObject) method.
(Overrides CartesianOnePointPropagatorComputeCurrentDefinitionHashCode.) |
| CreatePoint |
Creates a Point that represents the motion produced by this propagator.
(Inherited from CartesianOnePointPropagator.) |
| EnumerateDependencies |
Enumerates the dependencies of this object by calling
EnumerateT(T) for each object that this object directly depends upon.
Derived classes which contain additional dependencies MUST override this method, call the base
implementation, and enumerate dependencies introduced by the derived class.
(Overrides DefinitionalObjectEnumerateDependencies(DependencyEnumerator).) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| Freeze |
Freezes this object. Further attempts to modify it will result
in an ObjectFrozenException.
(Inherited from DefinitionalObject.) |
| FreezeAggregatedObjects |
Called by Freeze to also freeze any objects that are considered to be a part of this object.
Derived classes which contain additional aggregated objects MUST override this method, call the base
implementation, and freeze aggregated objects introduced by the derived class. The objects that need to be
frozen in this method are frequently created in this object's constructor and are not settable via
properties.
(Inherited from DefinitionalObject.) |
| GetDefinitionHashCode |
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.) |
| GetEvaluator | Gets an evaluator that can propagate at individual dates. This evaluator propagates the orbit state. The result of evaluating will be a MotionT corresponding to the orbital state at the given JulianDate expressed in the propagator's ReferenceFrame. Note: when evaluating with this evaluator, it may be more efficient to specify times using an arithmetically safe TimeStandard to avoid the need to convert in order to perform the propagation. The length of a time step may be different in different TimeStandards. So be careful when specifying times. |
| GetEvaluator(EvaluatorGroup) | Gets an evaluator that can propagate at individual dates. This evaluator propagates the orbit state from InitialConditions at OrbitEpoch based on the GravitationalParameter, J2ZonalHarmonicCoefficient, J4ZonalHarmonicCoefficient, and ReferenceDistance. The result of evaluating will be a Motion<Cartesian> corresponding to the orbital position and velocity at the given JulianDate expressed in the propagator's ReferenceFrame. |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetMotionReferenceFrame |
Gets the reference frame in which the motion is defined.
(Overrides CartesianOnePointPropagatorGetMotionReferenceFrame.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsSameDefinition |
Determines if this object has the same definition as another object.
(Inherited from DefinitionalObject.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Propagate(JulianDate, JulianDate, Duration, Int32, ReferenceFrame) | Calculates position (and zero or more derivatives) for regular time steps over an interval. Note: when propagating, it may be more efficient to specify times using an arithmetically safe TimeStandard to avoid the need to convert in order to perform the propagation. The length of a time step may be different in different TimeStandards. So be careful when specifying times. |
| Propagate(JulianDate, JulianDate, Duration, Int32, ReferenceFrame, ITrackCalculationProgress) | Calculates position (and zero or more derivatives) for regular time steps over an interval. Note: when evaluating with this evaluator, it may be more efficient to specify times using an arithmetically safe TimeStandard to avoid the need to convert in order to perform the propagation. The length of a time step may be different in different TimeStandards. So be careful when specifying times. |
| ThrowIfFrozen |
Throws ObjectFrozenException if this object IsFrozen.
This method should be called from any method or property that modifies this object.
(Inherited from DefinitionalObject.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
