| Name | Description | |
|---|---|---|
 | SumFunction Constructor | Overloaded. Initializes a new instance of the SumFunction class. |
| Name | Description | |
|---|---|---|
 | ResultPropertyName | Gets or sets the unique, case-sensitive property name from which the result of the statistical function can be retrieved. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| SourcePropertyName | Gets or sets the name of the column whose values will be used to calculate the result of the statistical function. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| Name | Description | |
|---|---|---|
 | IsInitialized | Gets a value indicating whether the Initialize method has been called, indicating that the types in which the values will be accumulated have been initialized. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
 | IsSealed | Gets a value indicating whether an instance of a statistical function is in an immutable state. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| PrerequisiteFunctions | Gets a list of the statistical functions whose results are required by the current function in order to calculate its own result. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| RequiresAccumulation | Gets a value indicating whether the statistical function needs to accumulate its own results. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| Name | Description | |
|---|---|---|
 | GetSourcePropertyNames | (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| Name | Description | |
|---|---|---|
 | Accumulate | Overridden. Accumulates the values required to calculate the result of the statistical function. |
| AccumulateChildResult | Overridden. Accumulates the values required to calculate the result of the statistical function from the results of a child group. |
 | CheckSealed | Checks whether an instance of a statistical function is in an immutable state. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| GetEquivalenceKey | Retrieves a value that represents the statistical function's unique equivalence key. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| GetResult | Overridden. Retrieves the result of the statistical function. |
| Initialize | Overridden. Initializes the statistical function specifying the types in which the values will be accumulated. |
| InitializeFromInstance | Initializes the properties of the current instance of the same-type statistical function when a new instance of the same function needs to be created. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| InitializePrerequisites | Initializes the prerequisite statistical functions defined by the PrerequisiteFunctions property. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| IsEquivalent | Retrieves a value indicating whether a statistical function is the equivalent of the current function such that both will return the same result for the same set of values. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| Reset | Overridden. Resets the statistical function to its original state. |
| Validate | Overridden. Validates the statistical function to ensure that it is able to calculate its result. |
