Is there a way that i can add in the OscMessage the function displayinformation()???
i just want to send wireless in my PC via oscP5 library whatever is into display() method into draw().
Something like :

OscMessage myMessage = new OscMessage ( "Characteristics" + information );
      myMessage.add(displayinformation);
    oscP5.send(myMessage, remoteLocation);
