Class Application

java.lang.Object
  consciouscode.util.Application

Direct Known Subclasses:

Launcher

public abstract class Application
extends Object

Basic startup functionality for an application. To create your application, subclass this and add code like the following:

    public static void main(String[] args)
    {
        new ApplicationSubclass().runSafely(args);
    }

The subclass must also provide an implementation of run(java.lang.String[]).

On startup, the application immediately renders (to System.out) the text provided by getBannerText(). Then it looks for a resource file called /system.properties. If found, the properties defined in that file are added to the System properties table, but properties that already have values (presumably defined at the java command line) will not be modified.

The application's code goes into the subclass's implementation of run(java.lang.String[]); the command-line parameters are passed-through from main. Implementations of run may throw any exception, since this class will properly handle them and render an error message to the console.
