evaluate

public ValueEval evaluate(int srcRowIndex,
                          int srcColumnIndex)

Description copied from interface: Function0Arg

see Function.evaluate(ValueEval[], int, int)

Specified by:

evaluate in interface Function0Arg

evaluate

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

Description copied from interface: Function1Arg

see Function.evaluate(ValueEval[], int, int)

Specified by:

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.
