java.lang.Object org.apache.poi.ss.formula.functions.Index
public final class Index
Implementation for the Excel function INDEX
Syntax :
INDEX ( reference, row_num[, column_num [, area_num]])
INDEX ( array, row_num[, column_num])
reference | typically an area reference, possibly a union of areas |
---|---|
array | a literal array value (currently not supported) |
row_num | selects the row within the array or area reference |
column_num | selects column within the array or area reference. default is 1 |
area_num | used when reference is a union of areas |

public ValueEval evaluate(ValueEval[] args, int srcRowIndex, int srcColumnIndex)
evaluate

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 evaluationsrcColumnIndex
- column index of the cell containing the formula under evaluation
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
.
