Class Details

class Gio.BufferedOutputStream(**kwargs)
Bases:

Gio.FilterOutputStream, Gio.Seekable

Abstract:

No

Structure:

Gio.BufferedOutputStreamClass

Buffered output stream implements [class`Gio`.FilterOutputStream] and provides for buffered writes.

By default, GBufferedOutputStream’s buffer size is set at 4 kilobytes.

To create a buffered output stream, use [ctor`Gio`.BufferedOutputStream.new], or [ctor`Gio`.BufferedOutputStream.new_sized] to specify the buffer’s size at construction.

To get the size of a buffer within a buffered input stream, use [method`Gio`.BufferedOutputStream.get_buffer_size]. To change the size of a buffered output stream’s buffer, use [method`Gio`.BufferedOutputStream.set_buffer_size]. Note that the buffer’s size cannot be reduced below the size of the data within the buffer.

classmethod new(base_stream)[source]
Parameters:

base_stream (Gio.OutputStream) – a Gio.OutputStream.

Returns:

a Gio.OutputStream for the given base_stream.

Return type:

Gio.OutputStream

Creates a new buffered output stream for a base stream.

classmethod new_sized(base_stream, size)[source]
Parameters:
Returns:

a Gio.OutputStream with an internal buffer set to size.

Return type:

Gio.OutputStream

Creates a new buffered output stream with a given buffer size.

get_auto_grow()[source]
Returns:

True if the self's buffer automatically grows, False otherwise.

Return type:

bool

Checks if the buffer automatically grows as data is added.

get_buffer_size()[source]
Returns:

the current size of the buffer.

Return type:

int

Gets the size of the buffer in the self.

set_auto_grow(auto_grow)[source]
Parameters:

auto_grow (bool) – a bool.

Sets whether or not the self's buffer should automatically grow. If auto_grow is true, then each write will just make the buffer larger, and you must manually flush the buffer to actually write out the data to the underlying stream.

set_buffer_size(size)[source]
Parameters:

size (int) – a #gsize.

Sets the size of the internal buffer to size.

Gio.BufferedOutputStream.props.buffer_size
Name:

buffer-size

Type:

int

Default Value:

4096

Flags:

READABLE, WRITABLE, CONSTRUCT
