marauroa.server.RWLock

This class is a Reader/Writters lock A Reader Writer Lock is a synchronization mechanism allowing access to data.
It allows multiple threads to read the data simultaneously, but only one thread at a time to update it.

Controlling concurrent access to a shared, mutable resource is a classic problem. Clients request, and later release, either read-only or read-write access to the resource. To preserve consistency but minimize waiting, one usually wishes to allow either any number of readers or a single writer, but not both, to have access at any one time.

While a thread is updating, no other thread can read the data. The name is misleading. It may cause you to think there are two locks; in reality there is a single lock that restricts both reading and writing.

  protected PlayerEntryContainer() {
    /* Initialize the random number generator */
    rand = new Random();
    rand.setSeed(new Date().getTime());


    lock = new RWLock();


    /* We initialize the list that will help us sort the player entries. */
    clientidMap = Collections.synchronizedMap(new HashMap<Integer, PlayerEntry>());
  }
