public class ScalarOccultationRegulatedDualCone
extends ScalarOccultationDualCone

Provides evaluators for percentage of occultation/eclipse at a position, as well as EclipseType using the dual cone shadow model.

The percentage runs from 0.0 (completely lit) to 1.0 (total eclipse).

This shadow model should only be used in a SimpleSolarRadiationForce in conjunction with SolarRadiationBoundaryMitigation. It performs differently than the normal ScalarOccultationDualCone in that it treats the penumbra shadow condition as umbra, and does not allow the occultation factor to change during a propagation step. This functionality is required for correct results from the boundary mitigator, but in all other circumstances the normal dual cone occultation model should be used.

Constructor Detail

ScalarOccultationRegulatedDualCone

public ScalarOccultationRegulatedDualCone()

Creates a new Scalar with a VectorType (get / set) of RadiationVectorType.CORRECT_FOR_LIGHT_TIME_DELAY_AND_ABERRATION. IlluminatingBody (get / set) and TargetPoint (get / set) must be set before an Evaluator is created, and generally at least one body should be added to OccludingBodies (get).

ScalarOccultationRegulatedDualCone

public ScalarOccultationRegulatedDualCone(CentralBody illuminatingBody,
                                          Point targetPoint,
                                          @Nonnull
                                          CentralBody... occludingBodies)

Creates a new Scalar from the given illuminating body, target point, and occluding bodies.

Parameters:

illuminatingBody - The illuminating body.

targetPoint - The target point.

occludingBodies - The occluding bodies.

ScalarOccultationRegulatedDualCone

public ScalarOccultationRegulatedDualCone(CentralBody illuminatingBody,
                                          Point targetPoint,
                                          @Nonnull
                                          Iterable<CentralBody> occludingBodies)

Creates a new Scalar from the given illuminating body, target point, and occluding bodies.

Parameters:

illuminatingBody - The illuminating body.

targetPoint - The target point.

occludingBodies - The occluding bodies.

ScalarOccultationRegulatedDualCone

public ScalarOccultationRegulatedDualCone(@Nonnull
                                          ScalarOccultationDualCone template)

Initializes a new instance of a ScalarOccultationRegulatedDualCone from a normal ScalarOccultationDualCone.

Parameters:

template - The normal Scalar representing dual cone occultation.

Method Detail

checkForSameDefinition

protected final boolean checkForSameDefinition(ScalarOccultationDualCone other)

Checks to determine if another instance has the same definition as this instance and returns true 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 false for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IEquatableDefinition.isSameDefinition(java.lang.Object).

Overrides:

checkForSameDefinition in class ScalarOccultationDualCone

Parameters:

other - The other instance to compare to this one.

Returns:

true if the two objects are defined equivalently; otherwise false.

checkForSameDefinition

protected boolean checkForSameDefinition(ScalarOccultationRegulatedDualCone other)

Checks to determine if another instance has the same definition as this instance and returns true 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 false for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IEquatableDefinition.isSameDefinition(java.lang.Object).

Parameters:

other - The other instance to compare to this one.

Returns:

true if the two objects are defined equivalently; otherwise false.

computeCurrentDefinitionHashCode

protected int 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 ScalarOccultationRegulatedDualCone.checkForSameDefinition(agi.foundation.celestial.ScalarOccultationDualCone) method.

Overrides:

computeCurrentDefinitionHashCode in class ScalarOccultationDualCone

Returns:

The computed hash code.

getPhaseParameter

public final PropagationStageParameter getPhaseParameter()

Gets a parameter which represents the propagation phase. In general, users should never need to explicitly set this property. It should only be set when multiple NumericalPropagator objects are running in the same EvaluatorGroup, such as when elements of a state require additional instances of a NumericalPropagator inside their implementation in order to produce their values. In such cases, it may be necessary to distinguish between the phase of the exterior propagator and the phase of the interior propagator. In these cases, it is up to the user to ensure that both the state and all of its elements are configured with the same parameter. Otherwise, the state will throw an exception when creating its propagator.

setPhaseParameter

public final void setPhaseParameter(PropagationStageParameter value)

Sets a parameter which represents the propagation phase. In general, users should never need to explicitly set this property. It should only be set when multiple NumericalPropagator objects are running in the same EvaluatorGroup, such as when elements of a state require additional instances of a NumericalPropagator inside their implementation in order to produce their values. In such cases, it may be necessary to distinguish between the phase of the exterior propagator and the phase of the interior propagator. In these cases, it is up to the user to ensure that both the state and all of its elements are configured with the same parameter. Otherwise, the state will throw an exception when creating its propagator.

getEvaluator

public ScalarEvaluator getEvaluator(EvaluatorGroup group)

Gets an evaluator that calculates occultation according to the dual cone shadow model. The occultation factor ranges from 0.0 (fully lit) to 1.0 (full occultation).

Overrides:

getEvaluator in class ScalarOccultationDualCone

Parameters:

group - The group with which to associate the new evaluator. By grouping evaluators that are often evaluated at the same Julian dates, common computations can be performed only once for the entire group instead of multiple times for each evaluator.

Returns:

An evaluator for this scalar.

Throws:

ArgumentNullException - Thrown when group is null.

PropertyInvalidException - Thrown when the property TargetPoint (get / set), IlluminatingBody (get / set), or OccludingBodies (get) or any of its members is null.
