Class CLITool2

  • All Implemented Interfaces:
    Logable
    public abstract class CLITool2
extends Object
implements Logable
    Basic class for writing command line tools. This allows for verbose, debug and help options automatically. It supports logging to a file and specifying a configuration file names. In short, a lot of the random grunt work for using the commons command line toolkit is here.

    • Method Detail

      • getComponentName

        public abstract String getComponentName()
        Returns the name of the configuration component (usually "server" or "client") that identifies the XML elements which might have the configuration. These are resolved by their name attribute.
        Returns:

      • setBufferedReader

        public void setBufferedReader​(BufferedReader bufferedReader)

      • getIoInterface

        public static IOInterface getIoInterface()

      • setIoInterface

        public static void setIoInterface​(IOInterface newIOInterface)

      • doIt

        public abstract void doIt()
                   throws Exception
        Does the actual work. This is where you put your executable code.
        Throws:
        Exception

      • getConfigurationNode

        protected org.apache.commons.configuration.tree.ConfigurationNode getConfigurationNode()

      • setConfigurationNode

        protected void setConfigurationNode​(org.apache.commons.configuration.tree.ConfigurationNode configurationNode)

      • initialize

        public void initialize()
                throws Exception
        Sets up the configuration and runtime environment. This is called typically in the constructors before anything else is called. Always call super on this method if you override it! At the end of this method, the configuration node has been found and set for you to call in your getLoader() method.
        Throws:
        Exception

      • help

        public abstract void help()
        This will be automatically invoked for you if the user supplies a help option. This should just print out to the command line (using the say(String) method), rather than logging the help.

      • defaultHelp

        public static void defaultHelp​(boolean printHeader)
        Convenience method. This prints out a short message describing the built-in options for this class. Best called at the end of your custom help method. Prints a header (informational line) if you wish.

        public String getConfigFile()

      • setConfigFile

        public void setConfigFile​(String configFile)

      • getLogfileName

        public String getLogfileName()

      • setLogfileName

        public void setLogfileName​(String logfileName)
