Description

A server sends and receives data to and from its associated clients (other programs connected to it). When a server is started, it begins listening for connections on the port specified by the port parameter. Computers have many ports for transferring data and some are commonly used so be sure to not select one of these. For example, web servers usually use port 80 and POP mail uses port 110.

Methods

write() | Writes data to all connected clients
available() | Returns the next client in line with a new message
stop() | Disconnects all clients and stops the server
disconnect() | Disconnect a particular client

Constructor

    Server(parent, port)

Parameters

parent | PApplet: typically use "this"
port | int: port used to transfer data
