MVC Mediator - enjoy client side programming and build robust applications quickly.

• higher level layer for application programming, brings Model-UI pattern to an application level
• support for commong application level UI development tasks:
  • value binding
  • command binding
  • value buffering (delay changes until commit, revert changes)
  • validation (errors, warnings, visual feedback support)
• component toolkit agnostic
• event strategy agnostic
• model agnostic
• support for custom bindings

• Guide programmer in design and rapid implementation of efficient, accurate applications
• Free programmer from boring tasks, such:
  • listener management (especially hidden memory leaks)
  • writing adapter classes for list, combo and table models
  • reliable and robust string parsing and formatting
• Bring Swing expertize to Swing non-experts
• solve JDK annoyances
• to shut up all critiques who trumpet that Smalltalk, Python, Ruby, X, Y... language is 10, 100, etc. more times productive than Java
• joy of client side programming
  • radical ease of use
  • having more fun

• Swing support (Text components, JLabel, JList, JComboBox, JSpinner, all kind of Buttons and menu items). Framework does not force You to use some subclasses of the components - You can use the ones provided by JDK or Your own specialized classes.
• Accessing data with chains of:
  • method calls (public or private access, static)
  • Java Beans access
  • Lists, Maps, Arrays access
  • JXpath rich access to complex Java object graphs and XML documents.
• Data type support (parsing, formatting, converting, validation)
  • all primitive types and their wrappers
  • java.util.Date,
  • java.sql.Date, java.sql.Time, java.sql.Timestamp,
  • BigInteger, BigDecimal
  • arrays, lists - concatenation, string tokenization and parsing
  • several localizable validation functions
• Event support
  • Beans style event/listener management
  • dozens predefined strategies for most frequently used events
  • any custom strategy is matter of 3 lines of code in one central place
  • java.util.Observable
• Chains of list decorators:
  • sorting
  • filtering
  • firing change events
• More than 40 000 lines of well tested code (includes comments)
