Method Detail

singleOperandEvaluate

protected final double singleOperandEvaluate(ValueEval arg,
                                             int srcCellRow,
                                             int srcCellCol)
                                      throws EvaluationException

Throws:

EvaluationException

evaluateArray

public ValueEval evaluateArray(ValueEval[] args,
                               int srcRowIndex,
                               int srcColumnIndex)

Specified by:

evaluateArray in interface ArrayFunction

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.

evaluate

public ValueEval evaluate(int srcRowIndex,
                          int srcColumnIndex,
                          ValueEval arg0,
                          ValueEval arg1)

Description copied from interface: Function2Arg

Specified by:
