public abstract class MultiOperandNumericFunction
extends Object
implements Function

This is the super class for all excel function evaluator classes that take variable number of operands, and where the order of operands does not matter

Method Detail

evaluate

public final ValueEval evaluate(ValueEval[] args,
                                int srcCellRow,
                                int srcCellCol)

Specified by:

evaluate in interface Function

Parameters:

args - the evaluated function arguments. Empty values are represented with BlankEval or MissingArgEval, never null.

srcCellRow - row index of the cell containing the formula under evaluation

srcCellCol - 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.

isSubtotalCounted

public boolean isSubtotalCounted()

Whether to count nested subtotals.
