public class SpreadSheetColumnsByName
extends AbstractSpreadSheetTransformer

Creates a new spreadsheet with the columns that matched the regular expression. It is possible to invert the matching sense as well.

Input/output:
- accepts:
adams.core.io.SpreadSheet
- generates:
adams.core.io.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: SpreadSheetColumnsByName
 

-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.
 

-reg-exp <adams.core.base.BaseRegExp> (property: regExp)
    The regular expression to match the column names against.
    default: .*
 

-invert-matching (property: invertMatching)
    If enabled, the matching sense is inverted, ie, only non-matching columns
    get output.
