FilesystemDataProvider

FilesystemDataProvider is a data model add-on for Vaadin 23(Flow) providing hierarchical
data of the filesystem, and it can be used to supply it to Tree and TreeGrid components.
This is fully server side add-on.

The inspiration of this add-on is to provide similar functionality than Vaadin 7’s
built in FilesystemContainer had. Hence it is useful for Vaadin 7 -> Vaadin 23 migration projects.

Components

• FileSelect: Field UI component that allows selecting a single file, value is File

• MultiFileSelect: Field UI component that allows selecting multiple files, value is Set

• FtpDataProvider: Data provider wrapper of the FTP client, uses appache commons ftp
