public class SpreadSheetSort
extends AbstractInPlaceSpreadSheetTransformer

Sorts the rows of the spreadsheet according to the selected column indices and sort order (ascending/descending).

Input/output:
- accepts:
adams.data.spreadsheet.SpreadSheet
- generates:
adams.data.spreadsheet.SpreadSheet

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
 

-name <java.lang.String> (property: name)
    The name of the actor.
    default: SpreadSheetSort
 

-annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default: 
 

-skip (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded 
    as it is.
 

-stop-flow-on-error (property: stopFlowOnError)
    If set to true, the flow gets stopped in case this actor encounters an error;
     useful for critical actors.
 

-sort-column <adams.core.Index> [-sort-column ...] (property: sortColumn)
    The columns to use for sorting; An index is a number starting with 1; the 
    following placeholders can be used as well: first, second, third, last_2,
     last_1, last
    default: first
 

-sort-order <adams.core.base.BaseBoolean> [-sort-order ...] (property: sortOrder)
    The order of sorting for the columns (true = ascending, false = descending
    ).
    default: true
