Method Detail

evaluate

public ValueEval evaluate(ValueEval[] args,
                          int srcRowIndex,
                          int srcColumnIndex)
Specified by:
evaluate in interface Function
Parameters:
args - the evaluated function arguments. Empty values are represented with BlankEval or MissingArgEval, never null.
srcRowIndex - row index of the cell containing the formula under evaluation
srcColumnIndex - 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.

evaluateFirstArg

public static int evaluateFirstArg(ValueEval arg0,
                                   int srcRowIndex,
                                   int srcColumnIndex)
                            throws EvaluationException
Throws:
EvaluationException
