    public class WekaGenericPLSMatrixAccess
extends AbstractTransformer
    Transformer that allows the extraction of internal PLS filter/classifier matrices, forwarding them as spreadsheets.
    See the respective PLS implementation for details on available matrix names (derived from: weka.filters.supervised.attribute.pls.AbstractPLS)

    Input/output:
    - accepts:
       weka.classifiers.Classifier
       weka.filters.Filter
       weka.core.GenericPLSMatrixAccess
       adams.flow.container.WekaModelContainer
    - generates:
       adams.data.spreadsheet.SpreadSheet


    Container information:

    -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: WekaGenericPLSMatrixAccess
 
    -annotation <adams.core.base.BaseAnnotation> (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 execution at this level gets stopped in case this 
    actor encounters an error; the error gets propagated; useful for critical 
    actors.
    default: false
 
    -silent <boolean> (property: silent)
    If enabled, then no errors are output in the console; Note: the enclosing 
    actor handler must have this enabled as well.
    default: false
 
    -matrix <java.lang.String> (property: matrix)
    The name of matrix to extract.
    default: P
