Need methods in DirectoryResource

[Jean-Yves Cronier]

I play a little with WebDAV (and MS Web Folder).

I try to create WebdavResource (extends 
com.noelios.restlet.local.DirectoryResource).

I saw privates fieds (targetFile and targetDirectory) initialized in 
constructor.

Is it appropriate to add those methods to 
com.noelios.restlet.local.DirectoryResource ? :



        public boolean isFile() {
                return this.targetFile;
        }

        public boolean isDirectory() {
                return this.targetDirectory;
        }
