Method Detail

evaluate

public Eval evaluate(Eval[] args,
                     int srcRowIndex,
                     short srcColumnIndex)
Specified by:
evaluate in interface Function
Parameters:
args - the evaluated function arguments. Elements of this array typically implement ValueEval. 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.
