示例1: ChooseSingleElementFromAreaInternal
/**
* @return possibly <tt>ErrorEval</tt>, and <c>null</c>
*/
private static ValueEval ChooseSingleElementFromAreaInternal(AreaEval ae,
int srcCellRow, short srcCellCol)
{
//if (false)
//{
// // this Is too simplistic
// if (ae.ContainsRow(srcCellRow) && ae.ContainsColumn(srcCellCol))
// {
// throw new EvaluationException(ErrorEval.CIRCULAR_REF_ERROR);
// }
// /*
// Circular references are not dealt with directly here, but it Is worth noting some Issues.
// ANY one of the return statements in this method could return a cell that Is identical
// to the one immediately being Evaluated. The evaluating cell Is identified by srcCellRow,
// srcCellRow AND sheet. The sheet Is not available in any nearby calling method, so that's
// one reason why circular references are not easy to detect here. (The sheet of the returned
// cell can be obtained from ae if it Is an Area3DEval.)
// Another reason there's little value in attempting to detect circular references here Is
// that only direct circular references could be detected. If the cycle involved two or more
// cells this method could not detect it.
// Logic to detect evaluation cycles of all kinds has been coded in EvaluationCycleDetector
// (and HSSFFormulaEvaluator).
