public class NumericalPropagatorDefinition
extends DefinitionalObject

The definitional object that creates a NumericalPropagator.

It consists of the overall propagation state which represents individual scalar, vector, or custom parameters within IntegrationElements (get) (which are integrated during propagation), and the AuxiliaryElements (get) (which are not). It also contains StateCorrectors (get) which correct the IntegrationElements and their derivatives in between propagation steps, the Epoch (get / set) of the initial conditions, and the Integrator (get / set) which integrates the IntegrationElements.

Call NumericalPropagatorDefinition.createPropagator() in order to create the defined NumericalPropagator.

Constructor Detail

NumericalPropagatorDefinition

public NumericalPropagatorDefinition()

Initializes a new instance.

NumericalPropagatorDefinition

protected NumericalPropagatorDefinition(@Nonnull
                                        NumericalPropagatorDefinition existingInstance,
                                        @Nonnull
                                        CopyContext context)

Initializes a new instance as a copy of an existing instance.

See ICloneWithContext.clone(CopyContext) for more information about how to implement this constructor in a derived class.

Parameters:

existingInstance - The existing instance to copy.

context - A CopyContext that controls the depth of the copy.

Throws:

ArgumentNullException - Thrown when existingInstance or context is null.

Method Detail

clone

public Object clone(CopyContext context)

Clones this object using the specified context.

This method should be implemented to call a copy constructor on the class of the object being cloned. The copy constructor should take the CopyContext as a parameter in addition to the existing instance to copy. The copy constructor should first call CopyContext.addObjectMapping(T, T) to identify the newly constructed instance as a copy of the existing instance. It should then copy all fields, using CopyContext.updateReference(T) to copy any reference fields.

A typical implementation of ICloneWithContext:

public static class MyClass implements ICloneWithContext {
    public MyClass(MyClass existingInstance, CopyContext context) {
        context.addObjectMapping(existingInstance, this);
        someReference = context.updateReference(existingInstance.someReference);
    }

    @Override
    public final Object clone(CopyContext context) {
        return new MyClass(this, context);
    }

    private Object someReference;
}

In general, all fields that are reference types should be copied with a call to CopyContext.updateReference(T). There are a couple of exceptions:

1. Fields that are aggregate parts of the object should always be copied. A referenced object is an aggregate if properties or methods on the object being copied can modify the externally-visible value of the referenced object.
2. If the semantics of the referenced object require that it have a single parent, owner, context, etc., and the object being copied is that parent, owner, or context, then the referenced object should always be copied.

If one of these exceptions applies, the CopyContext should be given an opportunity to update the reference before the reference is copied explicitly. Use CopyContext.updateReference(T) to update the reference. If CopyContext.updateReference(T) returns the original object, indicating that the context does not have a replacement registered, then copy the object manually by invoking a Clone method, a copy constructor, or by manually constructing a new instance and copying the values.

alwaysCopy = context.updateReference(existingInstance.alwaysCopy);
if (existingInstance.alwaysCopy != null && alwaysCopy == existingInstance.alwaysCopy) {
    alwaysCopy = (AlwaysCopy) existingInstance.alwaysCopy.clone(context);
}

If you are implementing an evaluator (a class that implements IEvaluator), the IEvaluator.updateEvaluatorReferences(agi.foundation.infrastructure.CopyContext) method shares some responsibilities with the copy context constructor. Code duplication can be avoided by doing the following:

1. For references to other evaluators ONLY, simply assign the reference in the constructor instead of calling CopyContext.updateReference(T). You should still call CopyContext.updateReference(T) on any references to non-evaluators.
2. Call IEvaluator.updateEvaluatorReferences(agi.foundation.infrastructure.CopyContext) as the last line in the constructor and pass it the same CopyContext passed to the constructor.
3. Implement IEvaluator.updateEvaluatorReferences(agi.foundation.infrastructure.CopyContext) as normal. See the reference documentation for IEvaluator.updateEvaluatorReferences(agi.foundation.infrastructure.CopyContext) for more information on implementing that method.

public MyClass(MyClass existingInstance, CopyContext context) {
    super(existingInstance, context);
    someReference = context.updateReference(existingInstance.someReference);
    evaluatorReference = existingInstance.evaluatorReference;
    updateEvaluatorReferences(context);
}

@Override
public void updateEvaluatorReferences(CopyContext context) {
    evaluatorReference = context.updateReference(evaluatorReference);
}

@Override
public Object clone(CopyContext context) {
    return new MyClass(this, context);
}

private Object someReference;
private IEvaluator evaluatorReference;

Specified by:

clone in interface ICloneWithContext

Specified by:

clone in class DefinitionalObject

Parameters:

context - The context to use to perform the copy.

Returns:

A new instance which is a copy of this object.

checkForSameDefinition

protected final boolean checkForSameDefinition(DefinitionalObject 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).

Specified by:

checkForSameDefinition in class DefinitionalObject

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(NumericalPropagatorDefinition 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 NumericalPropagatorDefinition.checkForSameDefinition(agi.foundation.infrastructure.DefinitionalObject) method.

Overrides:

computeCurrentDefinitionHashCode in class DefinitionalObject

Returns:

The computed hash code.

enumerateDependencies

public void enumerateDependencies(DependencyEnumerator enumerator)

Enumerates the dependencies of this object by calling DependencyEnumerator#enumerate(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.

Specified by:

enumerateDependencies in interface IEnumerateDependencies

Overrides:

enumerateDependencies in class DefinitionalObject

Parameters:

enumerator - The enumerator that is informed of the dependencies of this object.

freezeAggregatedObjects

protected void freezeAggregatedObjects()

Called by DefinitionalObject.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.

Overrides:

freezeAggregatedObjects in class DefinitionalObject

getEpoch

@Nonnull
public final JulianDate getEpoch()

Gets the time at which the initial conditions for each PropagationStateElement are defined.

setEpoch

public final void setEpoch(@Nonnull
                           JulianDate value)

Sets the time at which the initial conditions for each PropagationStateElement are defined.

getIntegrator

public final NumericalIntegrator getIntegrator()

Gets the NumericalIntegrator to use to integrate the IntegrationElements (get).

setIntegrator

public final void setIntegrator(NumericalIntegrator value)

Sets the NumericalIntegrator to use to integrate the IntegrationElements (get).

getStateParameter

public final PropagationStateParameter getStateParameter()

Gets a parameter which represents the state during propagation. In general, users should never need to explicitly set this property. It should only be set in cases where 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 state of the exterior propagator and the state of the interior propagator. In these cases, it is up to the user to ensure that both the NumericalPropagatorDefinition and all of its elements are configured with the same parameter. Otherwise, the definition will throw an exception when creating its propagator.

setStateParameter

public final void setStateParameter(PropagationStateParameter value)

Sets a parameter which represents the state during propagation. In general, users should never need to explicitly set this property. It should only be set in cases where 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 state of the exterior propagator and the state of the interior propagator. In these cases, it is up to the user to ensure that both the NumericalPropagatorDefinition and all of its elements are configured with the same parameter. Otherwise, the definition will throw an exception when creating its propagator.

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 NumericalPropagatorDefinition and all of its elements are configured with the same parameter. Otherwise, the definition 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 NumericalPropagatorDefinition and all of its elements are configured with the same parameter. Otherwise, the definition will throw an exception when creating its propagator.

getComputeInitialConditionsOnCreation

public final boolean getComputeInitialConditionsOnCreation()

Gets or sets a value indicating whether propagators created by this definition will have the initial conditions of their IncludeHighestDerivativeInOutput (get / set) and auxiliary elements computed in their CurrentState (get) just after creation.

This is set to true by default, however in some advanced use cases part of the propagation state is parameterized separately from the main propagator and not available for evaluation during the propagation creation process.

If you are receiving exceptions from invalid parameterization during propagator creation setting this to false is a possible fix. In that case right after the NumericalPropagator is created its CurrentState (get) will have the correct initial state values that were specified during the initialization of the state elements. However, the indices representing the auxiliary elements, or the IncludeHighestDerivativeInOutput (get / set) information of the state elements if applicable, will read 0.0 instead of their actual value. Once propagation begins, or Reset is called the state array will have the correct values.

setComputeInitialConditionsOnCreation

public final void setComputeInitialConditionsOnCreation(boolean value)

Gets or sets a value indicating whether propagators created by this definition will have the initial conditions of their IncludeHighestDerivativeInOutput (get / set) and auxiliary elements computed in their CurrentState (get) just after creation.

This is set to true by default, however in some advanced use cases part of the propagation state is parameterized separately from the main propagator and not available for evaluation during the propagation creation process.

If you are receiving exceptions from invalid parameterization during propagator creation setting this to false is a possible fix. In that case right after the NumericalPropagator is created its CurrentState (get) will have the correct initial state values that were specified during the initialization of the state elements. However, the indices representing the auxiliary elements, or the IncludeHighestDerivativeInOutput (get / set) information of the state elements if applicable, will read 0.0 instead of their actual value. Once propagation begins, or Reset is called the state array will have the correct values.

getIntegrationElements

@Nonnull
public final Collection<PropagationStateElement> getIntegrationElements()

Gets the collection of IntegrationStateElements which together define the state for the numerical integrator.

getAuxiliaryElements

@Nonnull
public final Collection<AuxiliaryStateElement> getAuxiliaryElements()

Gets the collection of AuxiliaryStateElements which together define the auxiliary output from the propagator. These values are computed after each step based on the calculations performed during integration but are not integrated themselves.

getStateCorrectors

@Nonnull
public final Collection<PropagationStateCorrector> getStateCorrectors()

Gets the collection of correctors which are called after each step but before values are recorded. The correctors operate on the last step taken to correct the state and its derivatives for any anomalies or constraint conditions encountered during the integration step.
