Class Args

java.lang.Object
  org.xmlBlaster.util.property.Args

public class Args
extends java.lang.Object

Evaluate parameters at process startup (args).

JDK 1.1 or higher only.

Example:

 If you call your application e.g. like that:

    java myapp -file myfile.txt

 you can access the paramater:

    String fileName = Args.getArg(args, "-file", "dummy.txt");

 (dummy.txt would be the fallback if no -file ... is given)
