__findattr_ex__
Description copied from class:PyObject
Attribute lookup hook. If the attribute is not found, null may be returned or a Py.AttributeError can be thrown, whatever is more correct, efficient and/or convenient for the implementing class. Client code should usePyObject.__getattr__(String)

with the appropriate args. The only reason to override this method is for performance.- Overrides:
__delattr__
in classPyObject

name
- the name which will be removed - must be an interned string .- See Also:
-

__enter__
Description copied from class:PyIOBase
Called at the start of a context-managed suite (supporting thewith
clause). -
fileno
Description copied from class:PyIOBase
Return a file descriptor for the stream. A CPython file descriptor is an int, but this is not the natural choice in Jython, since Java has no such convention of using integers. File descriptors should be passed around opaquely, so their actual type is irrelevant, as long as (say)_jyio.open(PyObject[], String[])
accepts the type thatRawIOBase.fileno()
returns. -
seek
public long seek(long pos, int whence) Description copied from class:PyIOBase
Position the read or write pointer at a given byte offsetpos
relative to a position indicated bywhence
.- If
whence
=0, the position will be set topos

Flush write buffers, or no-op for read-only and non-blocking streams. Irrespective of the concrete type of the i/o object, locally-buffered write data is written downstream. Whether the downstream in object is also flushed depends upon the specific type of this object. -
close
public void close()Description copied from class:PyIOBase
Close the stream. If closed already, this is a no-op. -
seekable
public boolean seekable()Description copied from class:PyIOBase
Is the stream capable of positioning the read/write pointer? -
_checkSeekable
Description copied from class:PyIOBase
Raise an error if the pointer of underlying IO stream is not capable of being positioned.- Overrides:
_checkSeekable
in classPyIOBase
- Parameters:
msg
- optional custom message
-
readable
public boolean readable()Description copied from class:PyIOBase
Is the stream readable? -
_checkReadable
Description copied from class:PyIOBase
Raise an error if the underlying IO stream is not readable.- Overrides:
_checkReadable
in classPyIOBase
- Parameters:
msg
- optional custom message
-
writable
public boolean writable()Description copied from class:PyIOBase
Is the stream writable? -
_checkWritable
Description copied from class:PyIOBase
Raise an error if the underlying IO stream is not writable.- Overrides:
_checkWritable
in classPyIOBase
- Parameters:
msg
- optional custom message
-
_checkClosed
Description copied from class:PyIOBase
Raise an error if the underlying IO stream is closed. (Note opposite sense fromPyIOBase._checkSeekable(java.lang.String)
, etc..- Overrides:
_checkClosed
in classPyIOBase
- Parameters:
msg
- optional custom message
-
__exit__
Description copied from class:PyIOBase
Called at the end of a context-managed suite (supporting thewith
clause), and will normally close the stream. -
isatty
public boolean isatty()Description copied from class:PyIOBase
Is the stream known to be an interactive console? This relies on the ability of the underlying stream to know, which is not always possible. -
readline
Description copied from class:PyIOBase
Return one line of text (bytes terminates by'\n'
), or the whole stream, whichever is shorter. -
readline
Description copied from class:PyIOBase
Return one line of text (bytes terminates by'\n'
), or the specified number of bytes, or the whole stream, whichever is shortest. -
readlines
Description copied from class:PyIOBase
Read a stream as a sequence of lines. -
writelines
Description copied from class:PyIOBase
Write an iterable sequence of strings to the stream.- Overrides:
writelines
in classPyIOBase
-
readall
Description copied from class:PyRawIOBase
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
.- Overrides:
readall
in classPyRawIOBase
- Returns:
- a PyString holding the bytes read or
Py.None
(when a non-blocking source is not ready with further data)
-
read
Description copied from class:PyRawIOBase
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().- Overrides:
read
in classPyRawIOBase
- 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)
-
readinto
Description copied from class:PyRawIOBase
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.";- Overrides:
readinto
in classPyRawIOBase
- 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
Description copied from class:PyRawIOBase
Write the given bytes or bytearray object to the underlying raw stream and return the number of bytes written.- Overrides:
write
in classPyRawIOBase
- Parameters:
b
- buffer of bytes to be written- Returns:
- the number of bytes written
-
