public class SpreadSheetInfo
extends AbstractTransformer

Outputs statistics of a SpreadSheet object.

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

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: SpreadSheetInfo
 

-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.
 

-type <NUM_COLUMNS|NUM_ROWS|COLUMN_NAME|COLUMN_TYPE|CELL_TYPES> (property: type)
    The type of information to generate.
    default: NUM_ROWS
 

-column-index <adams.core.Index> (property: columnIndex)
    The column index to use for generating column-specific information. 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: last
