List of nextDesktopId() Examples

Examples of nextDesktopId()

org.zkoss.zk.ui.sys.IdGenerator.nextDesktopId()

Returns the next desktop ID for the specified desktop, or null to generate the default ID.

Default (if null is returned): ID is generated randomly. In other words, the desktop's ID, by default, is not deterministic. To have a deterministric value, you have to implement this method.

Notice that UUID cannot be empty and can only have alphanumeric characters or underscore (i.e., a-z, A-Z, 0-9, and _).

Also notice that we can retrieve the execution by use of {@link Desktop#getExecution}, or {@link org.zkoss.zk.ui.Executions#getCurrent}. @return the next desktop ID, or null to generate the default ID.

      final WebAppCtrl wappc = (WebAppCtrl)_wapp;
      final DesktopCache dc = _sess != null ? wappc.getDesktopCache(_sess): null;
        //_sess is null if in a working thread
      final IdGenerator idgen = wappc.getIdGenerator();
      if (idgen != null)
        _id = idgen.nextDesktopId(this);
      if (_id == null)
        _id = nextDesktopId(dc);
      else if (idgen != null)
        ComponentsCtrl.checkUuid(_id);
      updateUuidPrefix();
