Implementation for Excel function OFFSET()

OFFSET returns an area reference that is a specified number of rows and columns from a reference cell or area.

Syntax:
OFFSET(reference, rows, cols, height, width)

reference is the base reference.
rows is the number of rows up or down from the base reference.
cols is the number of columns left or right from the base reference.
height (default same height as base reference) is the row count for the returned area reference.
width (default same width as base reference) is the column count for the returned area reference.

Method Detail

evaluate

public 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.
