The -builtin open function is defined in this module. - -At the top of the I/O hierarchy is the abstract base class IOBase. It -defines the basic interface to a stream. Note, however, that there is no -separation between reading and writing to streams; implementations are -allowed to raise an IOError if they do not support a given operation. - -Extending IOBase is RawIOBase which deals simply with the reading and -writing of raw bytes to a stream. FileIO subclasses RawIOBase to provide -an interface to OS files. - -BufferedIOBase deals with buffering on a raw byte stream (RawIOBase). Its -subclasses, BufferedWriter, BufferedReader, and BufferedRWPair buffer -streams that are readable, writable, and both respectively. -BufferedRandom provides a buffered interface to random access -streams. BytesIO is a simple stream of in-memory bytes. - -Another IOBase subclass, TextIOBase, deals with the encoding and decoding -of streams into text. TextIOWrapper, which extends it, is a buffered text -interface to a buffered raw stream (`BufferedIOBase`). Finally, StringIO -is a in-memory stream for text. - -Argument names are not part of the specification, and only the arguments -of open() are intended to be used as keyword arguments. - -data: - -DEFAULT_BUFFER_SIZE - - An int containing the default buffer size used by the module's buffered - I/O classes. open() uses the file's blksize (as obtained by os.stat) if - possible. -""" -# New I/O library conforming to PEP 3116. - -__author__ = ("Guido van Rossum <guido@python.org>, " - "Mike Verdone <mike.verdone@gmail.com>, " - "Mark Russell <mark.russell@zen.co.uk>, " - "Antoine Pitrou <solipsis@pitrou.net>, " - "Amaury Forgeot d'Arc <amauryfa@gmail.com>, " - "Benjamin Peterson <benjamin@python.org>") - -__all__ = ["BlockingIOError", "open", "IOBase", "RawIOBase", "FileIO", - "BytesIO", "StringIO", "BufferedIOBase", - "BufferedReader", "BufferedWriter", "BufferedRWPair", - "BufferedRandom", "TextIOBase", "TextIOWrapper", - "UnsupportedOperation", "SEEK_SET", "SEEK_CUR", "SEEK_END"] - - -import _io -import abc - -from _io import (DEFAULT_BUFFER_SIZE, BlockingIOError, UnsupportedOperation, - open, FileIO, BytesIO, StringIO, BufferedReader, - BufferedWriter, BufferedRWPair, BufferedRandom, - IncrementalNewlineDecoder, TextIOWrapper) - -OpenWrapper = _io.open # for compatibility with _pyio - -# for seek() -SEEK_SET = 0 -SEEK_CUR = 1 -SEEK_END = 2 - -# Declaring ABCs in C is tricky so we do it here. -# Method descriptions and default implementations are inherited from the C -# version however. -class IOBase(_io._IOBase): - __metaclass__ = abc.ABCMeta - -class RawIOBase(_io._RawIOBase, IOBase): - pass - -class BufferedIOBase(_io._BufferedIOBase, IOBase): - pass - -class TextIOBase(_io._TextIOBase, IOBase): - pass - -RawIOBase.register(FileIO) - -for klass in (BytesIO, BufferedReader, BufferedWriter, BufferedRandom, - BufferedRWPair): - BufferedIOBase.register(klass) - -for klass in (StringIO, TextIOWrapper): - TextIOBase.register(klass) -del klass |
