Jgoodies bindings + shared frequent changes

Question

I have a Java application that updates data at a variable speed (obtained from a fairly high speed data stream from my control, but up to 120 Kbytes / s), and I would like to display statistics such as the number of bytes / packets using the dialog box .

I look at JGoodies bindings and got something pre-working with artificial data obtained at a low speed.

What I would like to do, roughly speaking:

• create a bean class something like this:

  public class Statistics
  {
    private int bytes;
    private int goodPackets;
    private int badPackets;
    private int totalPackets;
  
    public int getBytes() { return bytes; }
    public int getGoodPackets() { return goodPackets; }
    public int getBadPackets() { return badPackets; }
    public int getTotalPackets() { return totalPackets; }
  
    public void update(/* TBD */) { /* updates the fields appropriately */ }
    public Statistics() { bytes=goodPackets=badPackets=totalPackets=0; }
  }
  
  Statistics stats;
  

• bind 4 fields to elements in my GUI

• can be called stats.update()at any speed necessary in my main application thread, where the call to “update” is what causes the listeners to change the GUI.
