All Implemented Interfaces:
  Simulator.Event

Direct Known Subclasses:
  FreeSpaceAir.RadioTicker, SimpleAir.RadioTicker

Enclosing class:
  GlobalClock

public static class GlobalClock.Ticker
extends GlobalClock.LocalMeet

The `Ticker` class is an event that fires in the local queues of participating threads. This class is necessary for ensuring the integrity of the global clock.

Field Summary

`long` | `period`

Fields inherited from class avrora.sim.util.GlobalClock.LocalMeet
`condition, count, goal, id`

Constructor Summary
`protected` | `GlobalClock.Ticker(long p)`

Method Summary
`void` | `parallelAction(SimulatorThread s)` The `parallelAction()` method implements the functionality that must be performed in parallel when the threads have joined at this local meet, and after the serial action has been completed.
`void` | `preSynchAction()` The `preSynchAction()` method implements the functionality that must be performed just after the thread enters the local meet, but before it blocks waiting for the other threads.
`void` | `serialAction()` The `serialAction()` method implements the functionality that must be performed in serial when the threads have joined at this local meet.

Method Detail

### preSynchAction

    public void preSynchAction()

  Description copied from class: `GlobalClock.LocalMeet`
  The `preSynchAction()` method implements the functionality that must be performed just after the thread enters the local meet, but before it blocks waiting for the other threads. It is called with the `condition` monitor held.

  Specified by:
    `preSynchAction` in class `GlobalClock.LocalMeet`

### serialAction

    public void serialAction()

  Description copied from class: `GlobalClock.LocalMeet`
  The `serialAction()` method implements the functionality that must be performed in serial when the threads have joined at this local meet. This method will execute in the last thread to enter the fire() method.

  Specified by:
    `serialAction` in class `GlobalClock.LocalMeet`

### parallelAction

    public void parallelAction(SimulatorThread s)

  Description copied from class: `GlobalClock.LocalMeet`
  The `parallelAction()` method implements the functionality that must be performed in parallel when the threads have joined at this local meet, and after the serial action has been completed. It will be called in each thread, with the parameter passed being the current SimulatorThread.

  Specified by:
    `parallelAction` in class `GlobalClock.LocalMeet`
  Parameters:
    `s` - the current `SimulatorThread` instance for this thread
