ParameterizedScalarVariable Class

A variable for use with TargetedSegmentListDifferentialCorrector that will change the value of a Scalar used in the computation of some value within the segment propagators getting propagated. For example, you can set the scalar density of the atmosphere to be the Value provided in this variable, which gets modified in the differential corrector.

Syntax
public class ParameterizedScalarVariable : SegmentPropagatorVariable

The ParameterizedScalarVariable type exposes the following members.

Constructors
  NameDescription
Public methodParameterizedScalarVariable

Initializes a new instance.

Before GetEvaluator(EvaluatorGroup) can be called, PerturbationValue and Segment must be configured, and Settings must be configured with a valid MaximumStep. Scaling defaults to NoScalingOnVariable.

Protected methodParameterizedScalarVariable(ParameterizedScalarVariable, CopyContext)
Initializes a new instance as a copy of an existing instance.
Public methodParameterizedScalarVariable(Double, Double, Double, SegmentDefinition)
Initializes a new instance with a specified initial value.
Public methodParameterizedScalarVariable(Double, Double, Double, SegmentDefinition, SolverVariableScaling)
Initializes a new instance with a specified initial value.

Properties
  NameDescription
Public propertyInitialValue
Gets or sets the initial value to use when the Value is first evaluated. Note that this initial value is neither scaled nor cross-validated in any way relative to the values in the SolverVariableSettings. This value will not show up in the iteration results.
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 propertyName
Gets or sets an optional name for this variable.
(Inherited from SegmentPropagatorVariable.)
Public propertyPerturbationValue
Gets or sets the perturbation value to use when computing a numerical derivative relative to this variable of a SolvableMultivariableFunction that uses SegmentPropagators.
(Inherited from SegmentPropagatorVariable.)
Public propertySegment
Gets or sets the segment that this variable will act on.
(Inherited from SegmentPropagatorVariable.)
Public propertySettings
Gets or sets the settings for the MultivariableFunctionSolver associated with this variable.
(Inherited from SegmentPropagatorVariable.)
Public propertyValue
Gets the Scalar to use that will be varied by a TargetedSegmentListOperatorEvaluator. Use this Scalar in the place of one that you want to solve for with the TargetedSegmentListDifferentialCorrector.

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 SegmentPropagatorVariable.)
Protected methodCheckForSameDefinition(ParameterizedScalarVariable)
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).
Protected methodCheckForSameDefinition(SegmentPropagatorVariable)
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 SegmentPropagatorVariableCheckForSameDefinition(SegmentPropagatorVariable).)
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 SegmentPropagatorVariableComputeCurrentDefinitionHashCode.)
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 SegmentPropagatorVariableEnumerateDependencies(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.
(Inherited from SegmentPropagatorVariable.)
Public methodGetDefinitionHashCode
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.)
Public methodGetEvaluator
Gets a SegmentPropagatorVariableEvaluator for this variable.
(Overrides SegmentPropagatorVariableGetEvaluator(EvaluatorGroup).)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
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.)
Protected methodValidateProperties
Validates that required properties are configured correctly in order to get an evaluator for this instance. Derived classes should call this method when implementing GetEvaluator(EvaluatorGroup), as well as validate their own properties.
(Inherited from SegmentPropagatorVariable.)

Remarks
Note that it is possible to use the Value in multiple SegmentDefinitions. If you do that, then the value computed will be changed for all of the SegmentPropagators that are propagated after, not just the Segment specified.
