java.lang.Object
  org.vishia.java2C.test.TestWaitNotify.WaitNotifyData

Enclosing class:

TestWaitNotify

public static final class TestWaitNotify.WaitNotifyData
extends java.lang.Object

This class is visible from outside, it is used from the notifying thread and from this thread, which waits for data.

x

int x

A value which is supplied with notify.

ctNewData

int ctNewData

Sequence counter to detect a notify. It is incremented on any notify().

TestWaitNotify.WaitNotifyData

public TestWaitNotify.WaitNotifyData()

notify

public void notify(int value)

Notify routine, it may be called from outside. New data are stored than. The notify()-call have to be placed in a synchronized- (mutex-)-block. Elsewhere in Java an exception is thrown. It is necessary to do so. That synchronized-block should be used to set the data, which are supplied with the notify action. Than the data and the notify-call are mutual exclusive handled. The Java-code is:

      synchronized(this){
        x = value;
        ctNewData +=1;
        notify();
      }  
 

The value is stored. The sequence counter is incremented to advertise the notify. Than notify is called. All this operations are done under mutex in the synchronized-block. The translated C-code is:

    synchronized_ObjectJc(& ((* (ythis)).base.object)); {
      ythis->x = value;
      ythis->ctNewData += 1;
      notify_ObjectJc(& ((* (ythis)).base.object), _thCxt);
    } endSynchronized_ObjectJc(& ((* (ythis)).base.object));
 

Parameters:

value - The value supplied with notify.
