public class Appender
extends JPanel
implements BeanCommon, Visible, Serializable, DataSource, DataSourceListener, TrainingSetListener, TestSetListener, InstanceListener, EventConstraints

A bean that appends multiple incoming data connections into a single data set. The incoming connections can be either all instance connections or all batch-oriented connections (i.e. data set, training set and test set). Instance and batch connections can't be mixed. An amalgamated output is created that is a combination of all the incoming attributes. Missing values are used to fill columns that don't exist in a particular incoming data set. If all incoming connections are instance connections, then the outgoing connection must be an instance connection (and vice versa for incoming batch connections).
