class expyriment.io.extras.TcpServer(port, default_package_size=None, start_listening=True)¶

A class implementing a TCP network server for a single client.

__init__(port, default_package_size=None, start_listening=True)¶

Create a TcpServer.

clear()¶

Read the stream empty.

close()¶

Close the connection to the client.

default_package_size¶

Getter for default_package_size.

is_connected¶

Getter for is_connected.

listen()¶

Listen for a connection on port.

logging¶

Getter for logging.

port¶

Getter for port.

send(data)¶

set_logging(onoff)¶

Set logging of this object on or off

Parameters:	onoff : bool set logging on (True) or off (False)

Notes

See also design.experiment.set_log_level fur further information about event logging.

wait(length, package_size=None, duration=None, callback_function=None, process_control_events=True)¶

Wait for data.

Parameters:

length : int The length of the data to be waited for in bytes. If not set, a single package will be waited for. package_size : int, optional The size of the package to be waited for, optional. If not set, the default package size will be used. If length < package_size, package_size = length. duration: int, optional The duration to wait in milliseconds. callback_function : function, optional function to repeatedly execute during waiting loop process_control_events : bool, optional process io.Keyboard.process_control_keys() and io.Mouse.process_quit_event() (default = True)

Returns:

data : str The received data. rt : int The time it took to receive the data in milliseconds.

Notes

This will also by default process control events (quit and pause). Thus, keyboard events will be cleared from the cue and cannot be received by a Keyboard().check() anymore!
