Method Details

read
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
Read until end of file, using multipleread()
operations on the underlying stream. If the firstread()
returnsNone
(only possible in the case of a non-blocking stream), this method returnsNone
.- Returns:
- a PyString holding the bytes read or
Py.None
(when a non-blocking source is not ready with further data)
-
readinto
Read up tolen(b)
bytes intobytearray 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
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
-
