getExecutor()

getExecutor(functionToken): Nullable<BaseFunction>

Obtain the operator of the function to reuse the calculation logic. The argument type accepted by the function is: FunctionVariantType. For instance, the sum formula capability is needed for the statistics bar. You can obtain the calculation result by using const sum = formulaService.getExecutor(FUNCTION_NAMES_MATH.SUM); sum.calculate(new RangeReferenceObject(range, sheetId, unitId), ref2, re3).

Parameters

Returns

Nullable<BaseFunction>
