BufferedInputStream

Buffered input stream implements #GFilterInputStream and provides for buffered reads.

By default, #GBufferedInputStream's buffer size is set at 4 kilobytes.

To create a buffered input stream, use g_buffered_input_stream_new(), or g_buffered_input_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_input_stream_get_buffer_size(). To change the size of a buffered input stream's buffer, use g_buffered_input_stream_set_buffer_size(). Note that the buffer's size cannot be reduced below the size of the data within the buffer.

Constructors

this this(GBufferedInputStream* gBufferedInputStream, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(InputStream baseStream): Creates a new #GInputStream from the given @base_stream, with a buffer set to the default size (4 kilobytes).
this this(InputStream baseStream, size_t size): Creates a new #GBufferedInputStream from the given @base_stream, with a buffer set to @size.

Members

Functions

fill ptrdiff_t fill(ptrdiff_t count, Cancellable cancellable): Tries to read @count bytes from the stream into the buffer. Will block during this read.
fillAsync void fillAsync(ptrdiff_t count, int ioPriority, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Reads data into @stream's buffer asynchronously, up to @count size. @io_priority can be used to prioritize reads. For the synchronous version of this function, see g_buffered_input_stream_fill().
fillFinish ptrdiff_t fillFinish(AsyncResultIF result): Finishes an asynchronous read.
getAvailable size_t getAvailable(): Gets the size of the available data within the stream.
getBufferSize size_t getBufferSize(): Gets the size of the input buffer.
getBufferedInputStreamStruct GBufferedInputStream* getBufferedInputStreamStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
peek size_t peek(ubyte[] buffer, size_t offset): Peeks in the buffer, copying data of size @count into @buffer, offset @offset bytes.
peekBuffer ubyte[] peekBuffer(): Returns the buffer with the currently available bytes. The returned buffer must not be modified and will become invalid when reading from the stream or filling the buffer.
readByte int readByte(Cancellable cancellable): Tries to read a single byte from the stream or the buffer. Will block during this read.
setBufferSize void setBufferSize(size_t size): Sets the size of the internal buffer of @stream to @size, or to the size of the contents of the buffer. The buffer can never be resized smaller than its current contents.

Mixins

__anonymous mixin SeekableT!(GBufferedInputStream): Undocumented in source.

Inherited Members

From FilterInputStream

gFilterInputStream GFilterInputStream* gFilterInputStream;: the main Gtk struct
getFilterInputStreamStruct GFilterInputStream* getFilterInputStreamStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
getType GType getType()
getBaseStream InputStream 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.
