public class CmisFetcher
extends AbstractNioFetcher<CmisFetcherConfig>

CMIS-enabled Content Management Systems (CMS) fetcher (Atom end-point), backed by a custom, read-only NIO.2 FileSystemProvider (CmisFileSystemProvider). The start path can be specified as: cmis:http://yourhost:port/path/to/atom. Optionally you can have a non-root starting path by adding the path name to the base URL, with an exclamation mark as a separator: cmis:http://yourhost:port/path/to/atom!/MyFolder/MySubFolder. Start paths are assumed to be Atom URLs.

protected boolean acceptRequest(@NonNull
 @NonNull FetchRequest fetchRequest)
