ValueEval evaluateArray(ValueEval[] args, int srcRowIndex, int srcColumnIndex)
args
- the evaluated function arguments. Empty values are represented with
BlankEval
or
MissingArgEval
, never
null
.
(args - 评估的函数参数。空值用 BlankEval 或 MissingArgEval 表示,绝不为 null。)
srcRowIndex
- row index of the cell containing the formula under evaluation
(srcRowIndex - 包含计算公式的单元格的行索引)
srcColumnIndex
- column index of the cell containing the formula under evaluation
(srcColumnIndex - 包含正在评估的公式的单元格的列索引)
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
.
(评估结果,可能是 ErrorEval,绝不为空。注意 - Excel 使用错误代码 #NUM!而不是 IEEE NaN,因此当数值函数计算为 Double.NaN 时,请务必将结果转换为 ErrorEval.NUM_ERROR。)
default ValueEval evaluateTwoArrayArgs(ValueEval arg0, ValueEval arg1, int srcRowIndex, int srcColumnIndex, java.util.function.BiFunction<ValueEval,ValueEval,ValueEval> evalFunc)
arg0
- the first function argument. Empty values are represented with
BlankEval
or
MissingArgEval
, never
null
(arg0 - 第一个函数参数。空值用 BlankEval 或 MissingArgEval 表示,绝不为 null)
arg1
- the first function argument. Empty values are represented with
(arg1 - 第一个函数参数。空值用)
srcRowIndex
- row index of the cell containing the formula under evaluation
(srcRowIndex - 包含计算公式的单元格的行索引)
srcColumnIndex
- column index of the cell containing the formula under evaluation
(srcColumnIndex - 包含正在评估的公式的单元格的列索引)
