Syntax
public class PropagationVector : PropagationStateElement

The PropagationVector type exposes the following members.

Constructors
Properties
  NameDescription
Public propertyAdaptiveWeights
Gets or sets the weights to be applied to the scalar values when computing the error which determines how to adapt the step size during integration. This is in addition to any weights used in the integration algorithm itself. If not set, the weights are initialized to 1.0 as a default value.
Public propertyDimension
Gets the number of parameters (per Order) within this element.
(Overrides PropagationStateElementDimension.)
Public propertyIdentification
Gets or sets the string identifying this instance in the overall output.
(Inherited from PropagationStateElement.)
Public propertyIncludeHighestDerivativeInOutput
Gets or sets a value indicating whether to include the derivative computed at each step with the output. If this is true, the output converted from the raw state will contain the derivative associated with the Order of the differential equation.
(Inherited from PropagationStateElement.)
Public propertyInitialState
Gets or sets the initial vector and its derivatives up to the order of the VectorDerivative.
Public propertyIntegrationValue
Gets a Vector object that is parameterized on a vector value in the state during integration. This vector is only valid while the NumericalPropagator is running. For more general use, a VectorInterpolator should be created from the NumericalPropagationStateHistory produced by the propagator.
Public propertyIsFrozen
Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an ObjectFrozenException will be thrown if an attempt is made to do so.
(Inherited from DefinitionalObject.)
Public propertyOrder
Gets the order of the differential equation corresponding to this element.
(Overrides PropagationStateElementOrder.)
Public propertyPropagationAxes
Gets or sets the Axes in which the propagation occurs. These are the axes in which the VectorDerivative is represented.
Public propertyStateParameter
Gets or 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 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 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 state and all of its elements are configured with the same parameter. Otherwise, the state will throw an exception when creating its propagator.
(Overrides PropagationStateElementStateParameter.)
Public propertyVectorDerivative
Gets or sets the derivative of the highest Order which specifies the motion of this vector parameter over time. The order that this vector represents will be determined by the number of values entered for the InitialState (its Order plus one).

Methods
  NameDescription
Protected methodCheckForSameDefinition(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 PropagationStateElement.)
Protected methodCheckForSameDefinition(PropagationStateElement)
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 PropagationStateElementCheckForSameDefinition(PropagationStateElement).)
Protected methodCheckForSameDefinition(PropagationVector)
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).
Public methodClone
Clones this object using the specified context.
(Overrides DefinitionalObjectClone(CopyContext).)
Protected methodComputeCurrentDefinitionHashCode
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 PropagationStateElementComputeCurrentDefinitionHashCode.)
Public methodEnumerateDependencies
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).)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
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 methodFreeze
Freezes this object. Further attempts to modify it will result in an ObjectFrozenException.
(Inherited from DefinitionalObject.)
Protected methodFreezeAggregatedObjects
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.
(Overrides DefinitionalObjectFreezeAggregatedObjects.)
Public methodGetConverter
Gets an instance of an output type which can convert the output of propagation back into the native type of this state element. This method is also responsible for configuring the state parameter and the state input indices on any parameterized geometry types used by this element. Each parameterized geometry type will have a static configuration method which will allow it to configure itself in a particular EvaluatorGroup.
(Overrides PropagationStateElementGetConverter(EvaluatorGroup, MotionInt32).)
Public methodGetDefinitionHashCode
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.)
Public methodGetDerivatives
This is used by the NumericalPropagatorDefinition to obtain an instance of a state element evaluator that can compute the derivatives of this element of the state during propagation. It cannot be used outside of a NumericalPropagator as the geometry for the propagation state will be unavailable.
(Overrides PropagationStateElementGetDerivatives(EvaluatorGroup).)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetStateUpdater
By default this method returns null. If a concrete base class of this type represents an element that has special behavior that takes place each time step prior to propagation, then override this method to produce an IUpdatePriorToStep object that the NumericalPropagator will call every time step.
(Inherited from PropagationStateElement.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodIsSameDefinition
Determines if this object has the same definition as another object.
(Inherited from DefinitionalObject.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodThrowIfFrozen
Throws ObjectFrozenException if this object IsFrozen. This method should be called from any method or property that modifies this object.
(Inherited from DefinitionalObject.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
