        URI the uri created from the path

        Returns:
        String path corresponding to the uri

      • URIToPath

        public static String URIToPath​(String uri)
        Return a system path from a non constrained path (uri, url, relative system path, ...)
        Parameters:
        uri - String the path to trasform in system path
        Returns:
        String the system path (absolute or relative)

      • getProtocol

        public static int getProtocol​(String path)
        Return the protocol of a path. A protocol can be:
        PathUtil.SYSTEM if the path is a system dependent path.
        PathUtil.URL_FILE if the path is a system url (file:/...).
        PathUtil.URL_HTTP if the path is a web path (http://...).
        PathUtil.URL_FTP if the path is a web file path (ftp://...).
        Parameters:
        path - String the path to check.

        int one of the integer value described above.

      • isAbsoluteURL

        public static boolean isAbsoluteURL​(String url)
        Return true if the URL given in parameter is absolute
        Parameters:
        url - String the url string to test
        Returns:
        boolean true if the url is absolute, false otherwise

      • isAbsolutePath

        public static boolean isAbsolutePath​(String path)
        Return true if the path given in parameter is absolute. A path is absolute if:
        On linux system
        The path start with /
        On windows system
        The path start with [A-Z]:
        Parameters:
        path - String the path to test
        Returns:
        boolean true if the path is absolute, false otherwise.

      • relativize

        public static String relativize​(URI uri,
                                URI root)
        Relativize given uri from the given root.
        Parameters:
        uri - URI the uri to relativize
        root - URI the root against the relativization is done
        Returns:
        String the relative path computed

        path - the path used to build a valid URL
        Returns:
        a valid URL

      • removeRoot
