Class

GioBufferedOutputStream

Description [src]

class Gio.BufferedOutputStream : Gio.FilterOutputStream
  implements Gio.Seekable {
  priv: GBufferedOutputStreamPrivate*
}

Buffered output stream implements GFilterOutputStream and provides for buffered writes.

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

To create a buffered output stream, use g_buffered_output_stream_new(), or g_buffered_output_stream_new_sized() to specify the buffer’s size at construction.

To get the size of a buffer within a buffered input stream, use g_buffered_output_stream_get_buffer_size(). To change the size of a buffered output stream’s buffer, use g_buffered_output_stream_set_buffer_size(). Note that the buffer’s size cannot be reduced below the size of the data within the buffer.

Ancestors

Implements

GSeekable

Constructors

g_buffered_output_stream_new

Creates a new buffered output stream for a base stream.

g_buffered_output_stream_new_sized

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

Instance methods

g_buffered_output_stream_get_auto_grow

Checks if the buffer automatically grows as data is added.

g_buffered_output_stream_get_buffer_size

Gets the size of the buffer in the stream.

g_buffered_output_stream_set_auto_grow

Sets whether or not the stream‘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.

g_buffered_output_stream_set_buffer_size

Sets the size of the internal buffer to size.

Methods inherited from GFilterOutputStream (3)

g_filter_output_stream_get_base_stream

Gets the base stream for the filter stream.

g_filter_output_stream_get_close_base_stream

Returns whether the base stream will be closed when stream is closed.

g_filter_output_stream_set_close_base_stream

Sets whether the base stream will be closed when stream is closed.

Methods inherited from GSeekable (5)

g_seekable_can_seek

Tests if the stream supports the GSeekableIface.

g_seekable_can_truncate

Tests if the length of the stream can be adjusted with g_seekable_truncate().

g_seekable_seek

Seeks in the stream by the given offset, modified by type.

g_seekable_tell

Tells the current position within the stream.

g_seekable_truncate

Sets the length of the stream to offset. If the stream was previously larger than offset, the extra data is discarded. If the stream was previously shorter than offset, it is extended with NUL (‘\0’) bytes.

Properties

Gio.BufferedOutputStream:auto-grow

Whether the buffer should automatically grow.

Gio.BufferedOutputStream:buffer-size

The size of the backend buffer, in bytes.

Properties inherited from GFilterOutputStream (2)

Gio.FilterOutputStream:base-stream

The underlying base stream on which the I/O ops will be done.

Gio.FilterOutputStream:close-base-stream

Whether the base stream should be closed when the filter stream is closed.

Signals

Signals inherited from GObject (1)

GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
