Class BeanBinder

java.lang.Object
  se.datadosen.util.BeanBinder

public class BeanBinder
extends java.lang.Object

Utility class for synchronizing a Swing GUI with JavaBean properties. Also synchronizes a bean with a property file or command line parameters. Synchronization is performed when calling getProperties() and setProperties(). Matching is done where the name of a property corresponds to the name of a GUI element.
