    Version, history and license.
    - 2023-07-22 ctor is private, should never called directly, only singleton.
    - 2023-07-22 experience with mkdir, refactored.
    - 2023-07-18 rename and using FileRemoteWalker.WalkInfo instead CurrDirChildren, the content is the same.
    - 2023-07-16 change of delete(FileRemote, EventWithDst) but this is now obsolete. Improve execDel(org.vishia.fileRemote.FileRemoteCmdEventData, EventWithDst).
    - 2023-07-16 WalkInfo is now subclass ot this, used for walkInfo in FileCallbackLocalDelete, but should be renamed to WalkInfo.
    - 2023-07-16 FileAccessorLocalJava7.WalkFileTreeVisitor.preVisitDirectory(Path, BasicFileAttributes) now set the first level always to selected but does not call callback. The first level is the entry, not to handle for the functionality. See comment there. Adequate for FileAccessorLocalJava7.WalkFileTreeVisitor.postVisitDirectory(Path, IOException).
    - 2023-04-06 Hartmut new: chg: execCmd(org.vishia.fileRemote.FileRemoteCmdEventData, EventWithDst) now also with copyFile, moveFile
    - 2023-02-21 some fine tuning
    - 2023-02-13 Hartmut new: FileAccessorLocalJava7.WalkFileTreeVisitor.debugOut as helper.
    - 2023-02-12 #walkFileTree(FileRemote, boolean, boolean, int, int, String, long, int, FileRemoteWalkerCallback, FileRemoteProgressEvData) with selection via mask, used for copy of selected files. Additional: mark during walk.
    - 2023-02-03 Hartmut chg: experience with Thread priority. It seems to be that the walker has generally a higher priority, it is not proper interuptable by the SWT graphic thread ?? Yet wait(10) after each directory in FileAccessorLocalJava7.WalkFileTreeVisitor.postVisitDirectory(Path, IOException) to allow the graphic thread working.
    - 2023-02-03 Hartmut chg: the #walkFileTreeExecInThisThread(FileRemote, boolean, boolean, String, long, int, FileRemoteWalkerCallback, FileRemoteProgressEvData) is called recursively by org.vishia.fileLocalAccessor.FileCallbackLocalCmp#offerParentNode(FileRemote). Hence it is bad to set progress.bDone = true; in this operation, it kills the progress visibility because it sets to bDone after a sub directory. It is shifted to #walkFileTree(FileRemote, boolean, boolean, boolean, String, long, int, FileRemoteWalkerCallback, FileRemoteProgressEvData) done after really finished.
    - 2023-02-03 Hartmut refactoring, the WalkFileTreeVisitorCheck is removed respectively merge to the FileAccessorLocalJava7.WalkFileTreeVisitor. It was a new feature: check with a duplicated implementation instead refactored implementation. Now it is refactored. Test: org.vishia.commander.Fcmd runs, org.vishia.fileRemote.test.TestFileRemote used for test.
    - 2015-11-13 Hartmut bugfix: FileAccessorLocalJava7.WalkFileTreeVisitor.postVisitDirectory(Path, IOException): The same directory was walked twice because the callback was called firstly. The callback forces a #walkFileTree(FileRemote, boolean, boolean, boolean, String, long, int, FileRemoteWalkerCallback) started in another thread. This marks all child files with FileRemote.mRefreshChildPending while the other thread has removed the FileRemote child instances which are marked with that. Therefore FileRemote instances were removed and created new, there are existing more as one for the same file after them. The order of execution is changed yet only, so the bug is not forced. The core of the bug is a thread safety. While a walkFileTree for a directory runs, another thread should wait for it or skip it because the other thread refreshes already in the near time.
    - 2015-03-27 Hartmut now children in WalkFileTreeVisitor.WalkInfo is deactivate because not used before. A seldom error of twice instances for the same children of a directory was watched.
    - 2014-12-21 Hartmut chg: The WalkFileTreeVisitor.WalkInfo#children is not used any more, the refreshing of children is done in the Map instance of FileRemote.children() with marking the children with FileRemote.mRefreshChildPending as flag bit while refreshing is pending and removing the files which's mark is remain after refresh. With them a new instance of a Map is not necessary.

    Constant Field Values
  - useFileChildren
```
private static final boolean useFileChildren
```
    Some experience possible: if true, then store File objects in FileRemote.children instead FileRemote objects. The File objects may be replaces by FileRemote later if necessary. This may be done in applications. The problem is: Wrapping a File with FileRemote does not change the reference in FileRemote.children automatically. It should be done by any algorithm. Therefore this compiler switch is set to false yet.

If it is especially a file on a remote device only able to reach via communication ( for example on an embedded device), the operation should wait for success.
    
    co - Command description. It is the payload of an command event.
    
    evBack - prepared event for back information or also for progress. The event knows a destination where the back event is processed. If this argument is null, no back information will be sent. This is sensible if bWait is true, and if the caller can check what is happen. Hint: Usual an instance of FileRemoteProgressEventConsumer can be used to execute the event, and also to wait for success on user level.
    
    Returns:
    
    null if executed successfully in another thread (bWait = false), else return null if no error.

```
    Executes walk file tree. Usual called in the execCmd(org.vishia.fileRemote.FileRemoteCmdEventData, EventWithDst) either in one of the FileAccessorLocalJava7.WalkerThread or immediately in the caller thread.
    
    Parameters:
    
    co - data what should be done, especially FileRemoteCmdEventData.callback describes what should be done with a file.
    
    bRefreshChildren - true then reads the properties of all children from the original file system.
    
    evBack - a progress event, also usable for quests with answer via the EventWithDst.getOpponent() prepared before call.
    
    debugOut -
  - evThread
```
public EventThread_ifc evThread()
```
    Description copied from interface: EventConsumer
    
    This operation should return that thread, which is associated to this consumer.
    
    Returns:
    
    null because it has not a typical event thread. See processEvent(EventObject)
  - processEvent
```
public int processEvent(java.util.EventObject ev)
```
    Processes immediately an event, but delegate to a free walkerThread It means the processing is finished in this thread, but the event is not relinquished yet immediately.
    
    Parameters:
    
    ev - The event. It contains some data. The type of the event is not specified here. Any events can be processed.
    
    Returns:
    
    0 or EventConsumer.mEventConsumed or EventConsumer.mEventDonotRelinquish etc. see list above. This value is forwarded to EventSource.notifyConsumed(int) and can be evaluated by the application in the calling thread or in any other thread which have access to implementation of EventSource.
