Class TotalOrder

  • All Implemented Interfaces:
    java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible
    public class TotalOrder
extends java.awt.Frame
    Originally written to be a demo for TOTAL order (code to be written by a student). In the meantime, it evolved into a state transfer demo. All members maintain a shared matrix and continually broadcast changes to be applied to a randomly chosen field (e.g. multiplication of field with new value, division, addition, subtraction). Each member can be started independently (starts to broadcast update messages to all members). When "Stop" is pressed, a stop message is broadcast to all members, causing them to stop sending messages. The "Clear" button clears the shared state; "GetState" refreshes it from the shared group state (using the state transfer protocol).

    If the demo is to be used to show total order, then the SEQUENCER protocol would have to be added to the stack.
