    type File

    type File struct {
    	// contains filtered or unexported fields

      File wraps a xrdfs.File and implements the following interfaces:

      - io.Closer
      - io.Reader
      - io.Writer
      - io.ReaderAt
      - io.WriterAt
      - io.Seeker

      func Open

      func Open(name string) (*File, error)

        Open opens the name file, where name is the absolute location of that file (xrootd server address and path to the file on that server.)


        f, err := xrdio.Open("root://")

        func OpenFrom

        func OpenFrom(fs xrdfs.FileSystem, name string) (*File, error)

          OpenFrom opens the file name via the given filesystem handle. name is the absolute path of the wanted file on the server.


          f, err := xrdio.OpenFrom(fs, "/some/path/to/file")

          func (*File) Close

          func (f *File) Close() error

            Close implements io.Closer.

            func (*File) Name

            func (f *File) Name() string

              Name returns the name of the file.

              func (*File) Read

              func (f *File) Read(data []byte) (int, error)

                Read implements io.Reader.

                func (*File) ReadAt

                func (f *File) ReadAt(data []byte, offset int64) (int, error)

                  ReadAt implements io.ReaderAt.

                  func (*File) Seek

                  func (f *File) Seek(offset int64, whence int) (int64, error)

                    Seek implements io.Seeker

                    func (*File) Stat

                    func (f *File) Stat() (os.FileInfo, error)

                    func (*File) Write

                    func (f *File) Write(data []byte) (int, error)

                      Write implements io.Writer.

                      func (*File) WriteAt

                      func (f *File) WriteAt(data []byte, offset int64) (int, error)

                        WriteAt implements io.WriterAt.

                        type URL

                        type URL struct {
                        	Addr string // address (host [:port]) of the server
                        	User string // user name to use to log in
                        	Path string // path to the remote file or directory

                          URL stores an absolute reference to a XRootD path.

                          func Parse

                          func Parse(name string) (URL, error)

                            Parse parses name into an xrootd URL structure.
