Class SetInstancesPanel

  • All Implemented Interfaces:
    java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

    public class SetInstancesPanel
    extends javax.swing.JPanel
    A panel that displays an instance summary for a set of instances and lets the user open a set of instances from either a file or URL. Instances may be obtained either in a batch or incremental fashion. If incremental reading is used, then the client should obtain the Loader object (by calling getLoader()) and read the instances one at a time. If batch loading is used, then SetInstancesPanel will load the data into memory inside of a separate thread and notify the client when the operation is complete. The client can then retrieve the instances by calling getInstances().
