 int srcColumnIndex,
 ValueEval arg1,
 ValueEval arg2)

Description copied from interface: Function2Arg

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

Specified by:

evaluate in interface Function2Arg

evaluate

public ValueEval evaluate(ValueEval[] args,
 OperationEvaluationContext ec)

Specified by:

evaluate in interface FreeRefFunction

Parameters:

args - the pre-evaluated arguments for this function. args is never null, nor are any of its elements.

ec - primarily used to identify the source cell containing the formula being evaluated. may also be used to dynamically create reference evals.

Returns:

never null. Possibly an instance of ErrorEval in the case of a specified Excel error (Exceptions are never thrown to represent Excel errors).
