    `PyObject` | `read(int n)` The read() method is implemented by calling readinto(); derived classes that want to support read() only need to implement readinto() as a primitive operation.
    `PyObject` | `readall()` Read until end of file, using multiple `read()` operations on the underlying stream.
    `PyObject` | `readinto(PyObject b)` Read up to `len(b)` bytes into `bytearray b` and return the number of bytes read.
    `PyObject` | `write(PyObject b)` Write the given bytes or bytearray object to the underlying raw stream and return the number of bytes written.

  - ### Method Detail

    - #### read

          public PyObject read(int n)

      The read() method is implemented by calling readinto(); derived classes that want to support read() only need to implement readinto() as a primitive operation. In general, readinto() can be more efficient than read().
      Parameters:
        `n` - number of bytes to read (if possible)
      Returns:
        a PyString holding the bytes read or `Py.None` (when a non-blocking source is not ready with further data)

    - #### readall

          public PyObject readall()

      Read until end of file, using multiple `read()` operations on the underlying stream. If the first `read()` returns `None` (only possible in the case of a non-blocking stream), this method returns `None`.
      Returns:
        a PyString holding the bytes read or `Py.None` (when a non-blocking source is not ready with further data)

    - #### readinto

          public PyObject readinto(PyObject b)

      Read up to `len(b)` bytes into `bytearray b` and return the number of bytes read. If the object is in non-blocking mode and no bytes are available, `None` is returned.";
      Parameters:
        `b` - byte array to try to fill
      Returns:
        number of bytes actually read or `Py.None` (when a non-blocking source is not ready with further data)

    - #### write

          public PyObject write(PyObject b)

      Write the given bytes or bytearray object to the underlying raw stream and return the number of bytes written.
      Parameters:
        `b` - buffer of bytes to be written
      Returns:
        the number of bytes written
