BufferedIOBase

io

class (source)

Base class for buffered IO objects.

The main difference with RawIOBase is that the read() method
supports omitting the size argument, and does not have a default
implementation that defers to readinto().

In addition, read(), readinto() and write() may raise
BlockingIOError if the underlying raw stream is in non-blocking
mode and not ready; unlike their raw counterparts, they will never
return None.

A typical implementation should not inherit from a RawIOBase
implementation, but wrap one.

Members of BufferedIOBase

d

detach: Disconnect this buffer from its underlying raw stream and return it.

r

raw: The underlying raw stream (a RawIOBase instance) that BufferedIOBase deals with.
read: Read and return up to n bytes.
read1: Read and return up to size bytes, with at most one read() call to the underlying raw stream.
readinto: Read bytes into a pre-allocated, writable bytes-like object b and return the number of bytes read.
readinto1: Read bytes into a pre-allocated, writable bytes-like object b, using at most one call to the underlying raw stream’s read() (or readinto()) method.

w

write: Write buffer b to the IO stream.
