Efl.Net.Socket_Simple (class)

Description

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 and an output Efl.Io.Queue. These are linked using a receiver and a sender Efl.Io.Copier.

The idea is that unlike the traditional Efl.Net.Socket which attempts 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 Efl.Io.Writer.can_write. This 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, then discarded with Efl.Io.Buffered_Stream.discard or Efl.Io.Buffered_Stream.clear.

When waiting for a complete message, you can just peek at its contents: if incomplete do nothing, if complete then use either Efl.Io.Reader.read to get a copy or manipulate a read-only reference from Efl.Io.Buffered_Stream.slice 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.

Inherited

Efl.Io.Buffered_Stream
protected set can_read (get, set) If true will notify Efl.Io.Reader.read can be called without blocking or failing.
protected set can_write (get, set) If true will notify Efl.Io.Writer.write can be called without blocking or failing.
clear Clears the incoming queue. Same as reading all data.
close Closes the Input/Output object.
close_on_exec (get, set) If true will automatically close resources on exec() calls.
close_on_invalidate (get, set) If true will automatically close() on object invalidate.
closed (get)
discard Discards the given number of bytes.
protected set eos (get, set) If true will notify end of stream.
eos_mark Marks the end-of-stream. Signals nothing else will be written.
finalize Implement this method to finish the initialization of your object after all (if any) user-provided configuration methods have been executed.
flush Forces writing all pending data to destination.
invalidate Implement this method to perform special actions when your object loses its parent, if you need to.
line_delimiter (get, set) If set incoming data will be checked for the delimiter and "line" events. The line may include the delimiter, unless it's end-of-stream in Efl.Io.Buffered_Stream.max_queue_size_input has been reached.
max_queue_size_input (get, set) Limits how big the input queue can grow, in bytes.
max_queue_size_output (get, set) Limits how big the output queue can grow in bytes.

read Reads data into a pre-allocated buffer.
read_chunk_size (get, set) Reads chunk size property, in bytes.
slice (get)
timeout_inactivity (get, set) Error as ETIMEDOUT if it becomes inactive for some time.
write Writes data from a pre-populated buffer.
Efl.Loop_Consumer
future_rejected Creates a new future that is already rejected to a specified error using the Efl.Loop_Consumer.loop.get.
future_resolved Creates a new future that is already resolved to a value.
loop (get)
parent (get, set) The parent of an object.
promise_new Create a new promise with the scheduler coming from the loop provided by this object.

Events

Inherited

Efl.Io.Buffered_Stream
error An error has occurred and I/O has stopped
finished Both read and write are finished.
line If Efl.Io.Buffered_Stream.line_delimiter is set, will be emitted with current line. The memory is only valid during event callback dispatched and should not be modified. Note that the line slice may not be inside Efl.Io.Buffered_Stream.slice.
progress Property Efl.Io.Buffered_Stream.progress changed
read,finished Same as Efl.Io.Reader "eos", for consistency.
slice,changed The read-slice returned by Efl.Io.Buffered_Stream.slice may have changed.
write,finished Efl.Io.Buffered_Stream.eos_mark was called and all available data was sent to destination
Efl.Io.Closer
closed Notifies closed, when property is marked as true
Efl.Io.Reader
can_read,changed Notifies can_read property changed.
eos Notifies end of stream, when property is marked as true.
Efl.Io.Writer
can_write,changed Notifies can_write property changed.
Efl.Object
del Object is being deleted. See Efl.Object.destructor.
destruct Object has been fully destroyed. It can not be used beyond this point. This event should only serve to clean up any reference you keep to the object.
invalidate Object is being invalidated and losing its parent. See Efl.Object.invalidate.
noref Object has lost its last reference, only parent relationship is keeping it alive. Advanced usage.
ownership,shared Object has acquired a second reference. It has multiple owners now. Triggered whenever increasing the refcount from one to two, it will not trigger by further increasing the refcount beyond two.
ownership,unique Object has lost a reference and only one is left. It has just one owner now. Triggered whenever the refcount goes from two to one.
