SyntaxThe ConstantCovariance3By3 type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | ConstantCovariance3By3 |
Initializes a new instance. The user must set OrientationAxes with SetOrientationAxes(Axes).
Sigmas is initialized to Zero.
|
| ConstantCovariance3By3(Cartesian, Axes) |
Creates a new instance from the specified constant size and the orientation axes.
|
 | ConstantCovariance3By3(ConstantCovariance3By3, CopyContext) | Initializes a new instance as a copy of an existing instance. |
Properties| Name | Description | |
|---|---|---|
 | IsFrozen |
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.) |
| OrientationAxes |
Gets the time-varying axes of the covariance ellipsoid. This property can be set with SetOrientationAxes(Axes).
(Overrides DynamicCovariance3By3OrientationAxes.) |
| Sigmas |
Gets or sets the Cartesian representing the constant Sigmas for the location point
uncertainty described by this instance. These are equal to the square root of the standard deviation of the covariances,
and are the semi-axes lengths of the covariance ellipsoid at one standard deviation of uncertainty.

Methods| Name | Description | |
|---|---|---|
| CheckForSameDefinition(ConstantCovariance3By3) |
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).
|
| 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 DynamicCovariance3By3.) |
| CheckForSameDefinition(DynamicCovariance3By3) |
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 DynamicCovariance3By3CheckForSameDefinition(DynamicCovariance3By3).) |
| 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 DynamicCovariance3By3ComputeCurrentDefinitionHashCode.) |
| 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.) |
| GetEllipsoidSizeEvaluator(Scalar) | Constructs an evaluator that calculates dimensions of the ellipsoid containing the uncertainty of a position over time. This is created from the standard deviation (or sigma) of the position variance over time, as well as the given Scalar factor of how many standard deviations of uncertainty to use. These sigmas correspond to the OrientationAxes. |
| GetEllipsoidSizeEvaluator(Scalar, EvaluatorGroup) | Constructs an evaluator that calculates dimensions of the ellipsoid containing the uncertainty of a position over time. This is created from the standard deviation (or sigma) of the position variance over time, as well as the given Scalar factor of how many standard deviations of uncertainty to use. These sigmas correspond to the OrientationAxes. |
| GetEvaluator |
Constructs an evaluator that calculates the size and orientation of the position covariance over time.
(Inherited from DynamicCovariance3By3.) |
| GetEvaluator(Axes) |
Constructs an evaluator that calculates the size and orientation of the position covariance over time.
(Inherited from DynamicCovariance3By3.) |
| GetEvaluator(EvaluatorGroup) |
Constructs an evaluator that calculates the size and orientation of the position covariance over time.
(Overrides DynamicCovariance3By3GetEvaluator(EvaluatorGroup).) |
| GetEvaluator(Axes, EvaluatorGroup) |
Constructs an evaluator that calculates the size and orientation of the position covariance over time.
(Overrides DynamicCovariance3By3GetEvaluator(Axes, EvaluatorGroup).) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetService |
Gets the service object of the specified type.
(Inherited from DynamicCovariance3By3.) |
| GetStandardDeviationEvaluator | Constructs an evaluator that calculates the standard deviation (or sigma) of the position variance over time. These sigmas correspond to the OrientationAxes. This is equivalent to calling GetEllipsoidSizeEvaluator(Scalar) with a sigma factor of 1.0. |
| GetStandardDeviationEvaluator(EvaluatorGroup) | Constructs an evaluator that calculates the standard deviation (or sigma) of the position variance over time. These sigmas correspond to the OrientationAxes. This is equivalent to calling GetEllipsoidSizeEvaluator(Scalar, EvaluatorGroup) with a sigma factor of 1.0. |
| 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.) |
| SetOrientationAxes |
Sets the OrientationAxes.
|
| 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.) |
