- Method Detail
  - getRequestQueue
```
RequestQueue getRequestQueue()
```
    Returns the request queue.
  - getNextKey
```
int getNextKey()
```
    Returns the next available key which is unique in the whole desktop.
  - getNextUuid
```
java.lang.String getNextUuid(Page page)
```
    Returns the next available UUID for a page. The returned UUID is unique in the desktop. You can consider it as unique in the whole session, though it may not be true if RawId is used (developer's responsibility to avoid conflict), integer overflow (too many UUID in one session, which can be considered as impossible), or a custom ID generator (IdGenerator) is used.
    
    Since:
    
    5.0.3
  - getNextUuid
```
java.lang.String getNextUuid(Component comp)
```
    Returns the next available UUID for a component. The returned UUID is unique in the desktop. You can consider it as unique in the whole session, though it may not be true if RawId is used (developer's responsibility to avoid conflict), integer overflow (too many UUID in one session, which can be considered as impossible), or a custom ID generator (IdGenerator) is used.
    
    Since:
    
    5.0.3
  - addComponent
```
void addComponent(Component comp)
```
    Adds a component to this page.
    It is used internally and developers shall not invoke it explicityly.
    
    Throws:
    
    java.lang.InternalError - if there is a component associated with the same UUID
  - mapComponent
```
Component mapComponent(java.lang.String uuid,
                       Component comp)
```
    Maps a component associated with the given UUID to this page. Notice that the given uuid can be different from comp's UUID (Component.getUuid()).
    If the given component is null, the mapping of UUID is removed.
    Unlike addComponent(org.zkoss.zk.ui.Component) and removeComponent(org.zkoss.zk.ui.Component, boolean), this method simply replaces the mapping if the given UUID is already mapped to the other component.
    It is used internally and developers shall not invoke it explicitly.
    
    Parameters:
    
    comp - the component to associate with the given UUID. If not, the association (i.e., mapping) is removed.
    
    Returns:
    
    the previous component that was associated with the given UUID.
    
    Since:
    
    6.0.0
  - removeComponent
```
boolean removeComponent(Component comp,
                        boolean recycleUuidAllowed)
```
    Removes a component to this page.
    It is used internally and developers shall not invoke it explicitly.
    
    Parameters:
    
    recycleUuidAllowed - whether it is OK to recycle UUID.
    
    Returns:
    
    whether UUID is recycled. If true, the caller shall reset UUID of the give component.
    
    Since:
    
    5.0.4
  - addPage
```
void addPage(Page page)
```
    Adds a page to this desktop. It must be called when a page is created.
    This is one of the only few method you could access before activating an execution.
  - removePage
```
void removePage(Page page)
```
    Removes a page from this desktop.
    NOTE: once a page is removed, you can NOT add it back. You shall just GC it.
  - setId
```
void setId(java.lang.String id)
```
    Sets the desktop identifier.
    It is callable only if it is the recovering phase, i.e., ExecutionCtrl.isRecovering() is true. In other words, callable only in the invocation of FailoverManager.recover(org.zkoss.zk.ui.Session, org.zkoss.zk.ui.Execution, org.zkoss.zk.ui.Desktop).
    
    Throws:
    
    java.lang.IllegalStateException - if it is NOT in recovering.
  - recoverDidFail
```
void recoverDidFail(java.lang.Throwable ex)
```
    Called when the recovering failed.
  - sessionWillPassivate
```
void sessionWillPassivate(Session sess)
```
    Notification that the session, which owns this desktop, is about to be passivated (a.k.a., serialized) by the Web container.
  - sessionDidActivate
```
void sessionDidActivate(Session sess)
```
    Notification that the session, which owns this desktop, has just been activated (a.k.a., deserialized) by the Web container.
  - destroy
```
void destroy()
```
    Called when the desktop is about to be destroyed.
  - recycle
```
void recycle()
```
    Called when the desktop has been recycled. More precisely, it is called when the desktop is no longer used and ready to be re-used later.
    
    Since:
    
    5.0.7
  - getSuspendedThreads
```
java.util.Collection<EventProcessingThread> getSuspendedThreads()
```
    Returns a collection of suspended event processing threads, or empty if no suspended thread at all.
    An event processing thread is an instance of EventProcessingThread
    Note: if you access this method NOT in an event listener for the SAME desktop, you have to synchronize the iteration (though the returned collection is synchronized). Of course, it is always safe to test whether it is empty (Collection.isEmpty()).
```
        //Use the following pattern IF it is not in the SAME desktop's listener
        Collection c = otherDesktop.getSuspendedThreads();
        if (c.isEmpty()) {
        //do something accordingly
        } else {
        synchronized (c) {
        for (Iterator it = c.iterator(); it.hasNext();) {
          //...
        }
        }
        }
```
  - ceaseSuspendedThread
```
boolean ceaseSuspendedThread(EventProcessingThread evtthd,
                             java.lang.String cause)
```
    Ceases the specified event thread.
    
    Parameters:
    
    cause - an arbitrary text to describe the cause. It will be the message of the thrown InterruptedException.
    
    Returns:
    
    true if the event processing thread is ceased successfully; false if no such thread or it is not suspended.
  - getDownloadMedia
```
Media getDownloadMedia(java.lang.String medId,
                       boolean reserved)
```
    Returns the media that is associated with Desktop.getDownloadMediaURI(org.zkoss.util.media.Media, java.lang.String), or null if not found.
    This method is used internally. Developers rarely need to access this method.
    
    Parameters:
    
    reserved - reserved for future use.
    
    Returns:
    
    the media or null if not found.
  - onPiggybackListened
```
void onPiggybackListened(Component comp,
                         boolean listen)
```
    Called when a component added or removed a listener for Events.ON_PIGGYBACK.
    The implementation usually uses it to optimize whether to call the listener when onPiggyback() is called.
    
    Parameters:
    
    comp - the component that adds an listener for Events.ON_PIGGYBACK. The component may or may not be a root component.
    
    listen - whether the listener is added (or removed).
    
    Since:
    
    3.0.0
  - onPiggyback
```
void onPiggyback()
```
    Called each time when ZK Update Engine retrieves events. It is used to implement the piggyback feature by posting the events (see Events.ON_PIGGYBACK). The implementation could post events here. It should not process event here (since event thread might be used).
    Used only internally. Application developers shall not call it.
    
    Since:
    
    3.0.0
  - getServerPush
```
ServerPush getServerPush()
```
    Returns the server-push controller, or null if it is not enabled yet.
  - enableServerPush
```
boolean enableServerPush(ServerPush serverpush)
```
    Enables the server-push feature with the specified server-push controller. If you want to use the default serverpush, use Desktop.enableServerPush(boolean) instead. This method allows the caller to provide a server push for more control.
    Example:
```
desktop.enableServerPush(new PollingServerPush(1000,6000,5));
```
    Notice: a server push controller can be used in one desktop. It cannot be shared.
    Parameters:
    
    serverpush - the server-push controller. If null, the server-push feature is disabled (for this desktop). Note: this method will invoke ServerPush.start(org.zkoss.zk.ui.Desktop), so the caller doesn't need to do it.
    
    Since:
    
    3.0.0
    
    See Also:
    
    Desktop.enableServerPush(boolean)
  - enableServerPush
```
boolean enableServerPush(boolean enable,
                         java.io.Serializable enabler)
```
    Enable/Disable serverpush using reference counting, so that multiple enablers can use the same serverpush and deregister whenever they want.
    
    Parameters:
    
    enable - true/false enable/disable serverpush
    
    enabler - the same reference must be used to disable again
    
    Returns:
    
    Currently only used by DesktopEventQueue to enable several eventqueues to use the same ServerPush

```
    Schedules a task to run under the server push of the given desktop asynchronously. It is called by Executions.schedule(org.zkoss.zk.ui.Desktop, org.zkoss.zk.ui.event.EventListener<T>, T). Don't call it directly.
    Like activateServerPush(long) and deactivateServerPush(), this method could be called in any thread, so the implementation of this method has to be safe for concurrent access.
    
    Parameters:
    
    task - the task to execute
    
    event - the event to be passed to the task (i.e., the event listener). It could null or any instance as long as the task recognizes it.
    
    Throws:
    
    java.lang.IllegalStateException - if the server push is not enabled.
    
    DesktopUnavailableException - if the desktop is removed (when activating).
    
    Since:
    
    5.0.6
  - scheduledServerPush
```
boolean scheduledServerPush()
```
    Returns if there is any scheduled task for server push.

  - activateServerPush
```
boolean activateServerPush(long timeout)
                    throws java.lang.InterruptedException
```
    Activates the current thread for accessing this desktop by the server push. It is called by Executions.activate(org.zkoss.zk.ui.Desktop). Don't call it directly.
    Like scheduleServerPush(org.zkoss.zk.ui.event.EventListener<T>, T), this method could be called in any thread, so it has to be safe for concurrent access.
    Note: the server push must be enabled first (by use of Desktop.enableServerPush(boolean)).
    
    Parameters:
    
    timeout - the maximum time to wait in milliseconds. Ignored (i.e., never timeout) if non-positive.
    
    Throws:
    
    java.lang.IllegalStateException - if the server push is not enabled.
    
    java.lang.InterruptedException

```
void service(AuRequest request,
             boolean everError)
```
    Processes an AU request. Notice that not only the requests for a desktop but also the requests for any component in the desktop will go thru this method.
    To override the default processing, register an AU request service AuService by invoking Desktop.addListener(java.lang.Object).
    1. This method first invokes the registered AU request service (AuService) one-by-one, until the first one returns true.
    2. If none of them returns true or no AU service at all, it checks if the request is targeting a component (i.e., AuRequest.getComponent() is not null).
    3. If it is targeting a component, it invokes ComponentCtrl.service(org.zkoss.zk.au.AuRequest, boolean) to handle the service.
    4. If it is not targeting a component (i.e., targeting to this desktop), it handles as follows.
      
      It handles the recognized requests, including onBookmarkChange, onURIChange and onClientInfo.
      
      If the request is not one of above, it converts the request to an event (by Event.getEvent(org.zkoss.zk.au.AuRequest)) and then posts the event (by Events.postEvent(org.zkoss.zk.ui.event.Event)).
    Notice that the registered AU request service (AuService) will be called, no matter the request is targeting a component or a desktop. And, it can 'intercept' or 'filter' it by returning false.
    To send responses to the client, use AbstractComponent.smartUpdate(java.lang.String, java.lang.Object), AbstractComponent.response(org.zkoss.zk.au.AuResponse) or Component.invalidate().
    If you want to intercept events, you can register a listener implementing EventInterceptor, or overriding afterProcessEvent(org.zkoss.zk.ui.event.Event).
    Parameters:
    
    everError - if any error ever occurred before processing this request. In other words, indicates if the previous request causes any exception.
