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).
