FilterOutputStream

Base class for output stream implementations that perform some kind of filtering operation on a base stream. Typical examples of filtering operations are character set conversion, compression and byte order flipping.

class FilterOutputStream : OutputStream {

protected

GFilterOutputStream* gFilterOutputStream;

GFilterOutputStream* getFilterOutputStreamStruct(bool transferOwnership);

void* getStruct();

this(GFilterOutputStream* gFilterOutputStream, bool ownedRef);

static GType getType();

OutputStream getBaseStream();

bool getCloseBaseStream();

void setCloseBaseStream(bool closeBase);

}

Constructors

this this(GFilterOutputStream* gFilterOutputStream, bool ownedRef): Sets our main struct and passes it to the parent class.

Functions

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.
getFilterOutputStreamStruct GFilterOutputStream* getFilterOutputStreamStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
setCloseBaseStream void setCloseBaseStream(bool closeBase): Sets whether the base stream will be closed when @stream is closed.

From OutputStream

gOutputStream GOutputStream* gOutputStream;: the main Gtk struct
getOutputStreamStruct GOutputStream* getOutputStreamStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
getType GType getType()
clearPending void clearPending(): Clears the pending flag on @stream.
close bool close(Cancellable cancellable): Closes the stream, releasing resources related to it.
closeAsync void closeAsync(int ioPriority, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Requests an asynchronous close of the stream, releasing resources related to it. When the operation is finished @callback will be called. You can then call g_output_stream_close_finish() to get the result of the operation.
closeFinish bool closeFinish(AsyncResultIF result): Closes an output stream.
flush bool flush(Cancellable cancellable): Forces a write of all user-space buffered data for the given @stream. Will block during the operation. Closing the stream will implicitly cause a flush.
flushAsync void flushAsync(int ioPriority, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Forces an asynchronous write of all user-space buffered data for the given @stream. For behaviour details see g_output_stream_flush().
flushFinish bool flushFinish(AsyncResultIF result): Finishes flushing an output stream.
hasPending bool hasPending(): Checks if an output stream has pending actions.
isClosed bool isClosed(): Checks if an output stream has already been closed.
isClosing bool isClosing(): Checks if an output stream is being closed. This can be used inside e.g. a flush implementation to see if the flush (or other i/o operation) is called from within the closing operation.
setPending bool setPending(): Sets @stream to have actions pending. If the pending flag is already set or @stream is closed, it will return %FALSE and set @error.
splice ptrdiff_t splice(InputStream source, GOutputStreamSpliceFlags flags, Cancellable cancellable): Splices an input stream into an output stream.
spliceAsync void spliceAsync(InputStream source, GOutputStreamSpliceFlags flags, int ioPriority, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Splices a stream asynchronously. When the operation is finished @callback will be called. You can then call g_output_stream_splice_finish() to get the result of the operation.
spliceFinish ptrdiff_t spliceFinish(AsyncResultIF result): Finishes an asynchronous stream splice operation.
vprintf bool vprintf(size_t bytesWritten, Cancellable cancellable, ErrorG error, string format, void* args): This is a utility function around g_output_stream_write_all(). It uses g_strdup_vprintf() to turn @format and @args into a string that is then written to @stream.
write ptrdiff_t write(ubyte[] buffer, Cancellable cancellable): Tries to write @count bytes from @buffer into the stream. Will block during the operation.
writeAll bool writeAll(ubyte[] buffer, size_t bytesWritten, Cancellable cancellable): Tries to write @count bytes from @buffer into the stream. Will block during the operation.
writeAllAsync void writeAllAsync(ubyte[] buffer, int ioPriority, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Request an asynchronous write of @count bytes from @buffer into the stream. When the operation is finished @callback will be called. You can then call g_output_stream_write_all_finish() to get the result of the operation.
writeAllFinish bool writeAllFinish(AsyncResultIF result, size_t bytesWritten): Finishes an asynchronous stream write operation started with g_output_stream_write_all_async().
writeAsync void writeAsync(ubyte[] buffer, int ioPriority, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Request an asynchronous write of @count bytes from @buffer into the stream. When the operation is finished @callback will be called. You can then call g_output_stream_write_finish() to get the result of the operation.
writeBytes ptrdiff_t writeBytes(Bytes bytes, Cancellable cancellable): A wrapper function for g_output_stream_write() which takes a #GBytes as input. This can be more convenient for use by language bindings or in other cases where the refcounted nature of #GBytes is helpful over a bare pointer interface.
writeBytesAsync void writeBytesAsync(Bytes bytes, int ioPriority, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): This function is similar to g_output_stream_write_async(), but takes a #GBytes as input. Due to the refcounted nature of #GBytes, this allows the stream to avoid taking a copy of the data.
writeBytesFinish ptrdiff_t writeBytesFinish(AsyncResultIF result): Finishes a stream write-from-#GBytes operation.
writeFinish ptrdiff_t writeFinish(AsyncResultIF result): Finishes a stream write operation.
writev bool writev(GOutputVector[] vectors, size_t bytesWritten, Cancellable cancellable): Tries to write the bytes contained in the @n_vectors @vectors into the stream. Will block during the operation.
writevAll bool writevAll(GOutputVector[] vectors, size_t bytesWritten, Cancellable cancellable): Tries to write the bytes contained in the @n_vectors @vectors into the stream. Will block during the operation.
writevAllAsync void writevAllAsync(GOutputVector[] vectors, int ioPriority, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Request an asynchronous write of the bytes contained in the @n_vectors @vectors into the stream. When the operation is finished @callback will be called. You can then call g_output_stream_writev_all_finish() to get the result of the operation.
writevAllFinish bool writevAllFinish(AsyncResultIF result, size_t bytesWritten): Finishes an asynchronous stream write operation started with g_output_stream_writev_all_async().
writevAsync void writevAsync(GOutputVector[] vectors, int ioPriority, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Request an asynchronous write of the bytes contained in @n_vectors @vectors into the stream. When the operation is finished @callback will be called. You can then call g_output_stream_writev_finish() to get the result of the operation.
writevFinish bool writevFinish(AsyncResultIF result, size_t bytesWritten): Finishes a stream writev operation.
