Method Detail

getCell

Object getCell(int icol)
        throws IOException

Returns the contents of one cell in this row.

Parameters:

icol - column index

Returns:

cell contents

Throws:

IOException - if there's a problem reading the value

getRow

Object[] getRow()
         throws IOException

Returns the contents of all the cells in this row.

Note that implementations are in general (unless otherwise restricted by subtype documented contracts) free to return the same array, with different contents, on subsequent invocations of this method, so callers should not rely on the contents being undisturbed.

Returns:

array with one element for each column of this row, containing cell data; may be reused by subsequent invocations

Throws:

IOException
