FileSystemNotifier Class

Namespace: Rebex.IO.FileSystem.Notifications

Assembly: Rebex.FileSystem.dll (version 7.0.9147)

Raises events for the FileSystemProvider operations.

Typical order of the related hook events that are associated with one file system operation:

Preview event (e.g. CreatePreview). Pre-hook event.
Surrogate event (e.g. CreateSurrogate). Pre-hook event.
Completed event (e.g. CreateCompleted). Post-hook event.

When the virtual file system is used in the FileServer component, then the server session, which contains information about the user and the active connection, can be accessed using Current property in the handler of the FileSystemNotifier event.

Remarks

Preview and Completed events are raised only for the top level ("root") operation. In this context top level ("root") operation means an operation initiated by the user of the file system. Only Surrogate events are raised for the file system internal/nested operations.

Events

Name	Description
CopyCompleted	Occurs after the FileSystemProvider copies instance of the NodeBase.
