PollableOutputStreamInterface
¶ The interface for pollable output streams.
The default implementation of can_poll always returns
True
.The default implementation of write_nonblocking calls
Gio.PollableOutputStream.is_writable
(), and then callsGio.OutputStream.write
() if it returnsTrue
. This means you only need to override it if it is possible that your is_writable implementation may returnTrue
when the stream is not actually writable.The default implementation of writev_nonblocking calls
Gio.PollableOutputStream.write_nonblocking
() for each vector, and converts its return value and error (if set) to aGio.PollableReturn
. You should override this where possible to avoid having to allocate aGLib.Error
to returnGio.IOErrorEnum.WOULD_BLOCK
