class Gio::BufferedOutputStream

Overview

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.

Constructor Detail

def self.new(base_stream : Gio::OutputStream) : self #

Creates a new buffered output stream for a base stream.


def self.new #

Initialize a new BufferedOutputStream.


def self.new(*, auto_grow : Bool? = nil, base_stream : Gio::OutputStream? = nil, buffer_size : UInt32? = nil, close_base_stream : Bool? = nil) #

def self.new_sized(base_stream : Gio::OutputStream, size : UInt64) : self #

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


Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


Instance Method Detail

def auto_grow : Bool #

Checks if the buffer automatically grows as data is added.


def auto_grow=(auto_grow : Bool) : Nil #

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.


def auto_grow? : Bool #

def buffer_size : UInt64 #

Gets the size of the buffer in the @stream.


def buffer_size=(value : UInt32) : UInt32 #

def buffer_size=(size : UInt64) : Nil #

Sets the size of the internal buffer to @size.
