Name

read()

Class

Client

Description

Returns a number between 0 and 255 for the next byte that's waiting in the buffer. Returns -1 if there is no byte, although this should be avoided by first checking available() to see if any data is available.

Examples

  • import processing.net.*; 
Client myClient;
int dataIn; 

void setup() {
  size(200, 200);
  // Connect to the local machine at port 5204.
  // This example will not run if you haven't
  // previously started a server on this port.
  myClient = new Client(this, "127.0.0.1", 5204);
}

void draw() {
  if (myClient.available() > 0) {
dataIn = myClient.read();
  }
  background(dataIn);
}
