ThreadWatchDog
public class ThreadWatchDog extends MutableThread (Code)
The ThreadWatchDog class is the watchdog used to monitor threads in an application. There are two dogs used to monitor, the ALPHA_DOG and the BETA_DOG. The BETA_DOG's sole responsibility is to monitor the ALPHA_DOG. The ALPHA_DOG monitors the BETA_DOG and all assigned threads for monitoring. If a thread dies, the dogs will report an exception. If the dead thread is a MutableThread, the dog will try to restart it.


Field Summary
public  intmWatchDogPollCount
     The attribute mWatchDogPollCount is added for test interest.


Method Summary
public synchronized  voidcheckAllThreads()
     The checkAllThreads method for a dog checks each thread which has been put into the HashMap.
public  voidclear()
    
public  voidendWatching()
    
public static synchronized  ThreadWatchDoggetInstance()
     The getInstance method insures that the ALPHA_DOG (and therefore also the BETA_DOG) is a singleton.
public synchronized  voidput(MutableThread aMutableThread)
     The put method puts a mutable thread into the HashMap for monitoring by a dog.
public synchronized  voidput(Thread aThread)
     The put method causes the dog to monitor the passed Thread.
public synchronized  voidremove(MutableThread aMutableThread)
    
public  voidrun()
     This is the run method for the thread.

Field Detail
mWatchDogPollCount
public int mWatchDogPollCount(Code)
The attribute mWatchDogPollCount is added for test interest. It shows how many times the polling has occurred within the dog.





Method Detail
checkAllThreads
public synchronized void checkAllThreads()(Code)
The checkAllThreads method for a dog checks each thread which has been put into the HashMap.



clear
public void clear()(Code)



endWatching
public void endWatching()(Code)



getInstance
public static synchronized ThreadWatchDog getInstance()(Code)
The getInstance method insures that the ALPHA_DOG (and therefore also the BETA_DOG) is a singleton. It is static so that it can be referenced throughout the application within the JVM.



put
public synchronized void put(MutableThread aMutableThread)(Code)
The put method puts a mutable thread into the HashMap for monitoring by a dog. Note that this is an overloaded method which also allows for non-mutable Threads to be monitored as well.



put
public synchronized void put(Thread aThread)(Code)
The put method causes the dog to monitor the passed Thread.



remove
public synchronized void remove(MutableThread aMutableThread)(Code)



run
public void run()(Code)
This is the run method for the thread.
