Class NotImplementedFunction

  • All Implemented Interfaces:
    Function

    public final class NotImplementedFunction
    extends Object
    implements Function
    This is the default implementation of a Function class. The default behaviour is to raise a POI internal error (NotImplementedFunctionException). This error should alert the user that the formula contained a function that is not yet implemented.

      • evaluate

        public ValueEval evaluate​(ValueEval[] operands,
                                  int srcRow,
                                  int srcCol)
        Specified by:
        evaluate in interface Function
        Parameters:
        operands - the evaluated function arguments. Empty values are represented with BlankEval or MissingArgEval, never null.
        srcRow - row index of the cell containing the formula under evaluation
        srcCol - column index of the cell containing the formula under evaluation
        Returns:
        The evaluated result, possibly an ErrorEval, never null. Note - Excel uses the error code #NUM! instead of IEEE NaN, so when numeric functions evaluate to Double.NaN be sure to translate the result to ErrorEval.NUM_ERROR.
