Parameters:
column - the info for the column being read
columnData - the actual column data for the column being read (which may be null depending on when the exception was thrown during the reading process)
rowState - the current row state for the caller
error - the error that was encountered
Returns:
replacement for this row's column
Throws:
IOException
