}

Performs one-time configuration of a Node to get it on its feet.

An alternative to the MIT ANTS ConfigurationManager.

Usage: NodeConfigure [options]

ActiveAddress: the active address of the Node. Must be an IP-like dotted-quad.

PhysicalAddress: the active address of the Node. Must be a host:port pair.

Options:

-consoleport : Start a telnet console on the given port.

-routes : Static routing table is in file.

-updateRoutes: If dynamic routing updates should be pushed out.

-application : Read appfile to configure & start an application.

-extension : Read extfile to configure and install an extension.

-msgprefix : Prefix all messages with

The files appfile and extfile are simple files that are unceremoniously pushed into KeyArgs. They should define the application.

XXX A hack. Move into PrimordialNode so that ConfigurationManager and NodeConfigure will be mutually exclusive.

Summary  |  Top

   public NodeConfigure() 

Default constructor

   protected void run(Flow flow, 
                      ThreadPool threadPool, 
                      String[] args, 
                      CommSpaceHandle commSpaceHandle) 

Configure this Node. Prints a usage message if insufficient arguments are given.

The flow that starts this ball rolling will become the basic flow in the system.

Parameter	Description
args	the node configuration. See the class documentation.

Overrides:

run in class FlowRun

   private void parseCommandLine(String[] args)  throws FileNotFoundException, IOException, InvalidKeyArgsException, AddressFormatException, NoSuchNodeAddress, InterruptedException, LineListException

Parse the command line arguments to NodeConfigure. Most arguments are passed into PrimordialNode in some fashion. However, -application and -extension arguments have their files parsed and put into the apps and exts return parameters.

DOES NOT RETURN.

   private static String[] grokArgFile(String filename)  throws FileNotFoundException, IOException, LineListException

Grok an arg file (for a weak definition of grok). Just turns the contents of the file into an array of Strings, one for each token.

   protected BufferHandle newBufferHandle() 

Part of the FlowRun interface

Overrides:

newBufferHandle in class FlowRun

See Also: core.FlowRun

   protected void recycleBufferHandle(BufferHandle bh) 

Part of the FlowRun interface

Overrides:

recycleBufferHandle in class FlowRun

See Also: core.FlowRun

   public static void main(String[] args)  throws Exception

This doesn't work. Its just here to prevent folks from getting really confused.

See Also: run
