ScalarSum Class

A Scalar defined by the addition of a list of scalars which may vary over time.
Inheritance Hierarchy

Namespace:  AGI.Foundation.Geometry
Assembly:  AGI.Foundation.Core (in AGI.Foundation.Core.dll) Version: 24.3.420.0 (24.3.420.0)
Syntax
public class ScalarSum : Scalar, IPartialDifferentiable, 
	IEquatableDefinition

The ScalarSum type exposes the following members.

Constructors
Properties
  NameDescription
Public propertyDimension
Gets the dimension of the values produced by the object. For example, Vectors would have a dimension of three, and Scalars of one. A PartialDerivativesEvaluator created by this type will have a "RowDimension" equal to this property, and a "ColumnDimension equal to the summation of the dimensions of the independent variables that this object is dependent on.
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 propertyScalarsToAdd
Gets the list of scalars to add together.

Methods
  NameDescription
Public methodAdd(Double)
Adds a fixed scalar to this one.
(Inherited from Scalar.)
Public methodAdd(Scalar)
Adds another scalar to this one.
(Inherited from Scalar.)
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 Scalar.)
Protected methodCheckForSameDefinition(Scalar)
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 ScalarCheckForSameDefinition(Scalar).)
Protected methodCheckForSameDefinition(ScalarSum)
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 ScalarComputeCurrentDefinitionHashCode.)
Public methodCreateScalarDerivative
Constructs a scalar which represents a derivative of this scalar.
(Inherited from Scalar.)
Public methodDivide(Double)
Divides this scalar (numerator) by a fixed value (denominator).
(Inherited from Scalar.)
Public methodDivide(Scalar)
Divides this scalar (numerator) by another one (denominator).
(Inherited from Scalar.)
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 methodGetDefinitionHashCode
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.)
Public methodGetEvaluator
Gets an evaluator that can be used to find the value of this scalar function at a given JulianDate.
(Inherited from Scalar.)
Public methodGetEvaluator(EvaluatorGroup)

Gets an evaluator that can be used to find the sum of the scalars, including derivatives up to the requested order.

In an effort to avoid excessively large call stacks the resulting evaluator will recursively collapse any child scalar that is also a ScalarSum into the parent evaluator. For example, (a + (b + c)) will become (a + b + c).

(Overrides ScalarGetEvaluator(EvaluatorGroup).)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetPartialDerivativesEvaluator
Gets an evaluator that calculates the partial derivatives of this scalar sum with respect to any of the independentVariables parameters that apply.
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.)
Public methodMultiply(Double)
Multiplies this scalar with a fixed value.
(Inherited from Scalar.)
Public methodMultiply(Scalar)
Multiplies another scalar with this one.
(Inherited from Scalar.)
Public methodPower
Raises this scalar to the given fixed exponent.
(Inherited from Scalar.)
Public methodSubtract(Double)
Subtracts a fixed scalar from this one.
(Inherited from Scalar.)
Public methodSubtract(Scalar)
Subtracts another scalar from this one.
(Inherited from Scalar.)
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.)
