class Efl.Net.Socket.Simple (Efl.Io.Buffered_Stream, Efl.Net.Socket) {
|

[[A wrapper socket offering an easy to use, buffered I/O.
|
|
|
|
The simple socket encapsulates an actual @Efl.Net.Socket, and
|
|
uses it with an @Efl.Io.Buffered_Stream, which creates an input
|
|
@Efl.Io.Queue, an output @Efl.Io.Queue and these are linked
|
|
using a receiver and a sender @Efl.Io.Copier.
|
|
|
|
The idea is that unlike traditional @Efl.Net.Socket that will
|
|
attempt to write directly to socket and thus may take less data
|
|
than requested, this one will keep the pending data in its own
|
|
buffer, feeding to the actual socket when it
|
|
@Efl.Io.Writer.can_write. That makes its operation much simpler
|
|
as @Efl.Io.Writer.write will always take the full data -- allows
|
|
"write and forget", if unlimited (see
|
|
@Efl.Io.Buffered_Stream.max_queue_size_output).
|
|
|
|
Reading is also much simpler since received data is kept in an
|
|
@Efl.Io.Queue, thus its size can be queried with
|
|
@Efl.Io.Buffered_Stream.pending_read and read with
|
|
@Efl.Io.Reader.read or peeked with
|
|
@Efl.Io.Buffered_Stream.slice_get, then discarded with
|
|
@Efl.Io.Buffered_Stream.discard or
|
|
@Efl.Io.Buffered_Stream.clear.
|
|
|
|
Then when waiting for a complete message, just peek at its
|
|
contents, if not complete do nothing, if complete then either
|
|
@Efl.Io.Reader.read to get a copy or manipulate a read-only
|
|
reference from @Efl.Io.Buffered_Stream.slice_get and then
|
|
@Efl.Io.Buffered_Stream.discard
|
|
|
|
The actual socket is set with the constructor method
|
|
@Efl.Io.Buffered_Stream.inner_io.set and can be retrieved with
|
|
@Efl.Io.Buffered_Stream.inner_io.get, which should be used with
|
|
care.
