C# Class System.IO.FileSystemWatcher.RunningInstance

State and processing associatd with an active watch operation. This state is kept separate from FileSystemWatcher to avoid race conditions when a user starts/stops/starts/stops/etc. in quick succession, resulting in the potential for multiple active operations. It also helps with avoiding rooted cycles and enabling proper finalization.

Private Methods

Méthode	Description
AddDirectoryWatch ( WatchedDirectory parent, string directoryName ) : void	Adds a watch on a directory to the existing inotify handle.
AddDirectoryWatchUnlocked ( WatchedDirectory parent, string directoryName ) : void	Adds a watch on a directory to the existing inotify handle.
CancellationCallback ( ) : void	Callback invoked when cancellation is requested. Removes all watches, which will cause the active processing loop to shutdown.
ProcessEvents ( ) : void	Main processing loop. This is currently implemented as a synchronous operation that continually reads events and processes them... in the future, this could be changed to use asynchronous processing if the impact of using a thread-per-FileSystemWatcher is too high.
ReadName ( int position, int nameLength ) : string	Reads a UTF8 string from _buffer starting at the specified position and up to the specified length. Null termination is trimmed off (the length may include many null bytes, not just one, or it may include none).
RemoveWatchedDirectory ( WatchedDirectory directoryEntry, bool removeInotify = true ) : void	Removes the watched directory from our state, and optionally removes the inotify watch itself.
RemoveWatchedDirectoryUnlocked ( WatchedDirectory directoryEntry, bool removeInotify ) : void	Removes the watched directory from our state, and optionally removes the inotify watch itself.
RunningInstance ( FileSystemWatcher watcher, SafeFileHandle inotifyHandle, string directoryPath, bool includeSubdirectories, Interop notifyFilters, CancellationToken cancellationToken ) : Microsoft.Win32.SafeHandles	Initializes the instance with all state necessary to operate a watch.
Start ( ) : void
TryReadEvent ( NotifyEvent &notifyEvent ) : bool	Read events from the inotify handle into the supplied array.
