Class JavaGroups.JavaStack.Configurator 

java.lang.Object
   |
   +----JavaGroups.JavaStack.Configurator
public class Configurator
extends Object
The task if this class is to setup and configure the protocol stack. A string describing the desired setup, which is both the layering and the configuration of each layer, is given to the configurator which creates and configures the protocol stack and returns a reference to the top layer (Protocol).

Future functionality will include the capability to dynamically modify the layering of the protocol stack and the properties of each layer.

The configuration string has a number of entries, separated by a ':' (semi).

o SetupProtocolStack 
 public Protocol SetupProtocolStack(String configuration,
                                    ProtocolStack st) throws Exception
The configuration string has a number of entries, separated by a ':' (semi). Each entry consists of the name of the protocol, followed by an optional configuration of that protocol. The configuration is enclosed in parentheses, and contains entries which are name/value pairs connected with an assignment sign (=) and separated by a semicolon. 
UDP(in_port=5555;out_port=4445):FRAG(frag_size=1024)

The first entry defines the bottommost layer, the string is parsed left to right and the protocol stack constructed bottom up. Example: the string "UDP(in_port=5555):FRAG(frag_size=32000):DEBUG" results is the following stack:

   -----------------------
  | DEBUG                 |
  |-----------------------|
  | FRAG frag_size=32000  |
  |-----------------------|
  | UDP in_port=32000     |
   -----------------------

o StartProtocolStack 
 public void StartProtocolStack(Protocol bottom_prot)
o StopProtocolStack 
 public void StopProtocolStack(Protocol start_prot)
o FindProtocol 
 public Protocol FindProtocol(Protocol prot_stack,
                              String name)
o main 
 public static void main(String args[])
