    public class SpreadSheetTransformHeaderCells
extends AbstractInPlaceSpreadSheetTransformer
implements CallableActorUser
    Transforms header cells with a callable transformer.
    In case of transformers having Object or Unknown in their types of classes that they accept, no proper type can be inferred automatically. Therefore it is recommended to manually enforce the 'input type'.

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


    -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING
 
    -name <java.lang.String> (property: name)
    The name of the actor.
    default: SpreadSheetTransformHeaderCells
 
    -annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default:
 
    -skip <boolean> (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
    default: false
 
    -stop-flow-on-error <boolean> (property: stopFlowOnError)
    If set to true, the flow gets stopped in case this actor encounters an error;
     useful for critical actors.
    default: false
 
    -no-copy <boolean> (property: noCopy)
    If enabled, no copy of the spreadsheet is created before processing it.
    default: false
 
    -force-input-type <boolean> (property: forceInputType)
    If enabled, the input type is forced to a user-specified type, rather than
    trying to determine type based on data types that the callable transformer
    accepts.
    default: false
 
    -input-type <MISSING|STRING|BOOLEAN|LONG|DOUBLE|DATE|DATETIME|TIME|OBJECT> (property: inputType)
    The input type to use in case the input type is enforced.
    default: STRING
 
    -skip-missing <boolean> (property: skipMissing)
    If enabled, missing cells are skipped.
    default: true
 
    -missing-replacement-value <java.lang.String> (property: missingReplacementValue)
    The string representation of the value to use for replacing missing values.
    default:
 
    -missing-replacement-type <MISSING|STRING|BOOLEAN|LONG|DOUBLE|DATE|DATETIME|TIME|OBJECT> (property: missingReplacementType)
    The data type to use for the replacement value for missing values.
    default: STRING
 
    -transformer <adams.flow.core.CallableActorReference> (property: transformer)
    The callable transformer to apply to the header cells.
    default: unknown
