ScalarSum Class 
Namespace: AGI.Foundation.Geometry
The ScalarSum type exposes the following members.
Name  Description  

ScalarSum 
Initializes a new instance. The user must add Scalars to the list of ScalarsToAdd.
 
ScalarSum(IEnumerableScalar) 
Constructs the sum of a list of Scalars.
 
ScalarSum(Scalar) 
Constructs the sum of the given Scalars.
 
ScalarSum(ScalarSum, CopyContext)  Initializes a new instance as a copy of an existing instance. 
Name  Description  

Dimension 
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.
 
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.)  
ScalarsToAdd 
Gets the list of scalars to add together.

Name  Description  

Add(Double) 
Adds a fixed scalar to this one.
(Inherited from Scalar.)  
Add(Scalar) 
Adds another scalar to this one.
(Inherited from Scalar.)  
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 derivedclass instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Inherited from Scalar.)  
CheckForSameDefinition(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 derivedclass instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Overrides ScalarCheckForSameDefinition(Scalar).)  
CheckForSameDefinition(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 derivedclass instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
 
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 ScalarComputeCurrentDefinitionHashCode.)  
CreateScalarDerivative 
Constructs a scalar which represents a derivative of this scalar.
(Inherited from Scalar.)  
Divide(Double) 
Divides this scalar (numerator) by a fixed value (denominator).
(Inherited from Scalar.)  
Divide(Scalar) 
Divides this scalar (numerator) by another one (denominator).
(Inherited from Scalar.)  
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.
(Overrides DefinitionalObjectFreezeAggregatedObjects.)  
GetDefinitionHashCode 
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.)  
GetEvaluator 
Gets an evaluator that can be used to find the value of this scalar function at a given JulianDate.
(Inherited from Scalar.)  
GetEvaluator(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).  
GetHashCode  Serves as the default hash function. (Inherited from Object.)  
GetPartialDerivativesEvaluator 
Gets an evaluator that calculates the partial derivatives of this scalar sum
with respect to any of the independentVariables parameters that apply.
 
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.)  
Multiply(Double) 
Multiplies this scalar with a fixed value.
(Inherited from Scalar.)  
Multiply(Scalar) 
Multiplies another scalar with this one.
(Inherited from Scalar.)  
Power 
Raises this scalar to the given fixed exponent.
(Inherited from Scalar.)  
Subtract(Double) 
Subtracts a fixed scalar from this one.
(Inherited from Scalar.)  
Subtract(Scalar) 
Subtracts another scalar from this one.
(Inherited from Scalar.)  
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.)
