problem with splitStrings
« on: Dec 7th, 2004, 11:11pm » |
|
i am attempting to use the splitStrings method to break up a string coming from another program (CarnivoreXP) through the telnet port. i then am attempting to use parts of the array as variables. basically, i need to use the data coming in from carnivore as variables in if/then statements, but there is too much data, so i am attempting to break it down to something more managable.
however, i keep getting an out of bounds error on the array and i cannot figure out why
here is the pertinent code:
Socket socket;
BufferedReader packetreader;
CarnivoreListener CL;
String packet;
String packet_datestamp;
String packet_fromIP;
String packet_fromPort;
String packet_toIP;
String packet_toPort;
void setup(){
size(800, 200);
textFont(loadFont("GillSans.vlw.gz"), 24);
Sonia.start(this, 44100);
mySample = new Sample("sine.aif");
}
{
CL = new CarnivoreListener();
CL.startListening();
}
void loop(){
background(50,50,50);
fill(130,130,130);
text("data from Carnivore", 10, 30);
packet = CL.getPacket();
fill(200,200,200);
text(packet, 10, 50);
String list[] = splitStrings(packet);
The error message is as follows:
Error while running applet.
java.lang.ArrayIndexOutOfBoundsException: -1

i think this might be a bug (in versions .68, maybe .69) ... should not give an exception if string is empty.
make sure your string is not empy:
Code:
String list[];
if ( !packet.equals("") )
{
list = splitStrings(packet);
}

problem gone?

yeah, this is a bug in 68 that was fixed in 69.

I am trying to use the default carnivore script for processing 69 alpha and it is still giving me the splitStrings error.

the question is not which version of the script you use, but which software-version ... if you're on .68 -> have you tried my workaround (above)?

Sorry I was not using the default carnivore code but the code that was posted a while back with splitStrings and it did not work. By the way I am using .69. If you have this working could you post some code for me to test.

i have not been able to get this to work - the splitStrings method in verson 69 now returns the error message:
no method named "splitStrings" was found in type "client".
does anyone know if this is another bug, or is the problem in my scripting?

splitStrings was renamed split() in revision 69, sorry for the confusion (this sort of info can be found in revisions.txt or elsewhere on the board).
