Class CommandLineClient

java.lang.Object
  CommandLineClient

All Implemented Interfaces:

ClientMessageWriter

public class CommandLineClient
extends java.lang.Object
implements ClientMessageWriter

This class defines a command-line (non-GUI) application that may serve as a client of the SLAMD server. All of the configuration is done through command-line options. This is a good client to run as a background process.

Constructor Summary

CommandLineClient(java.lang.String[] args)
Parses the command line parameters and connects to the SLAMD server to accept and process job requests.

Method Summary

void	displayUsage() Displays usage information for this program.
static void	main(java.lang.String[] args) Passes off all the work to the constructor so that we can pass in a reference to this class to the client.
void	processConfigFile(java.lang.String configFile) Processes the contents of the specified config file.
boolean	usingVerboseMode() Indicates whether the message writer is using verbose mode and therefore will display messages written with the writeVerbose method.
void	writeMessage(java.lang.String message) Writes the specified message to standard output.
void	writeVerbose(java.lang.String message) Writes the specified message to standard output if verbose mode is enabled.
