Class Boot

java.lang.Object

java.lang.Thread

org.elkoserver.foundation.boot.Boot

All Implemented Interfaces:

Runnable

public class Boot
extends Thread

This is the universal startup class for applications using Elko. It performs the necessary initializations that all applications require, then launches the application itself by instantiating an instance of the application boot class and calling its boot() method.

The name of the application boot class should be the second argument on the Java command line, according to the following usage:

     java org.elkoserver.foundation.boot.Boot bootclass args...
 

The boot class must implement Bootable.

In addition to regular application command line parameters, property settings may also be given on the command line. They are interpreted according to the format in BootProperties.scanArgs(java.lang.String[]). Arguments that set property values are removed from the arguments array before it is presented to the application.

Method Detail

main

public static void main(String[] args)

Create a Boot object and start it running.

Parameters:

args - Command line arguments per the Java language spec.

run

public void run()

The run method mandated by the Thread class. This method is required to be public by Java's scoping rules, but you should not call it yourself. Java's rules don't allow you to declare run() to throw any exceptions, so this just wraps a call to the private method startApplication() in a try/catch block. The guts of startup are in another method for improved legibility.

Specified by:

run in interface Runnable

Overrides:

run in class Thread
