BufferedOutputStream

Buffered output stream implements gio.FilterOutputStream and provides for buffered writes.

By default, gio.BufferedOutputStream's buffer size is set at 4 kilobytes.

To create a buffered output stream, use BufferedOutputStream.new, or BufferedOutputStream.newSized to specify the buffer's size at construction.

To get the size of a buffer within a buffered input stream, use BufferedOutputStream.getBufferSize. To change the size of a buffered output stream's buffer, use BufferedOutputStream.setBufferSize. Note that the buffer's size cannot be reduced below the size of the data within the buffer.

Constructors

this this(GBufferedOutputStream* gBufferedOutputStream, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(OutputStream baseStream): Creates a new buffered output stream for a base stream.
this this(OutputStream baseStream, size_t size): Creates a new buffered output stream with a given buffer size.

Members

Functions

getAutoGrow bool getAutoGrow(): Checks if the buffer automatically grows as data is added.
getBufferSize size_t getBufferSize(): Gets the size of the buffer in the stream.
getBufferedOutputStreamStruct GBufferedOutputStream* getBufferedOutputStreamStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
setAutoGrow void setAutoGrow(bool autoGrow): 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.
setBufferSize void setBufferSize(size_t size): Sets the size of the internal buffer to size.

Variables

gBufferedOutputStream GBufferedOutputStream* gBufferedOutputStream;: the main Gtk struct

Inherited Members

From FilterOutputStream

gFilterOutputStream GFilterOutputStream* gFilterOutputStream;: the main Gtk struct
getFilterOutputStreamStruct GFilterOutputStream* getFilterOutputStreamStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
getType GType getType()
getBaseStream OutputStream getBaseStream(): Gets the base stream for the filter stream.
getCloseBaseStream bool getCloseBaseStream(): Returns whether the base stream will be closed when stream is closed.
setCloseBaseStream void setCloseBaseStream(bool closeBase): Sets whether the base stream will be closed when stream is closed.

From SeekableIF

getSeekableStruct GSeekable* getSeekableStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
getType GType getType()
canSeek bool canSeek(): Tests if the stream supports the GSeekableIface
canTruncate bool canTruncate(): Tests if the length of the stream can be adjusted with g_seekable_truncate().
seek bool seek(long offset, GSeekType type, Cancellable cancellable): Seeks in the stream by the given offset, modified by type.
tell long tell(): Tells the current position within the stream.
truncate bool truncate(long offset, Cancellable cancellable): 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 previouly shorter than offset, it is extended with NUL ('\0') bytes.
