public class ODFSpreadSheetReader
extends AbstractMultiSheetSpreadSheetReaderWithMissingValueSupport

Reads ODF (Open Document Format) spreadsheet files.
If a row contains only empty cells, this is interpreted as the end of the sheet.

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to 
    the console (0 = off).
    default: 0
    minimum: 0
 

-data-row-type <DENSE|SPARSE> (property: dataRowType)
    The type of row to use for the data.
    default: DENSE
 

-sheets <adams.core.Range> (property: sheetRange)
    The range of sheets to load; A range is a comma-separated list of single 
    1-based indices or sub-ranges of indices ('start-end'); 'inv(...)' inverts 
    the range '...'; the following placeholders can be used as well: first, 
    second, third, last_2, last_1, last
    default: first
 

-missing <java.lang.String> (property: missingValue)
    The placeholder for missing values.
    default: ?
 

-text-columns <java.lang.String> (property: textColumns)
    The range of columns to treat as text; A range is a comma-separated list 
    of single 1-based indices or sub-ranges of indices ('start-end'); 'inv(..
    .)' inverts the range '...'; the following placeholders can be used as well:
