Class ChildMain

  • All Implemented Interfaces:
    java.lang.Runnable
    public class ChildMain
extends java.lang.Thread
    A wrapper class that invokes another class' main(String[]). This particular class uses several system properties to control features:
    • Redirecting System.out and System.err.
    • Displaying a minimized window in the Windows taskbar.
    This class is normally not invoked directly. Instead, it is invoked by the LaunchTask class.
