Aspose::Cells::AbstractCalculationEngine::ForceRecalculate method
AbstractCalculationEngine::ForceRecalculate method
Whether force given function to be recalculated always when calculating shared formulas.
virtual bool Aspose::Cells::AbstractCalculationEngine::ForceRecalculate(const U16String &functionName)
| Parameter | Type | Description |
|---|---|---|
| functionName | const U16String& | name of the function. Generally it is custom function’s name. If ProcessBuiltInFunctions is true, then built-in functions will also be checked here. |
ReturnValue
true if the specified function needs to be recalculated always.
Remarks
For shared formulas, multiple cells share the same function. If the function’s parameters keep same for those cells too, then generally this function needs to be calculated only once. So for performance consideration we only calculate such kind of function once too(Calculate(CalculationData) is called only once, instead of being called repeatedly for every cell). However, for user’s custom implementation, maybe the function, especially the custom function, needs to be calculated differently for different cells. If so, user needs to override this method to make it return true for the function. And for Calculate(CalculationData), the given CalculationData.CalculatedValue may have been initialized with the cached value of previous calculation.
