Class OpenORBLoader

java.lang.Object

org.openorb.orb.config.OpenORBLoader

All Implemented Interfaces:

ORBLoader

public class OpenORBLoader
extends java.lang.Object
implements ORBLoader

This class gets information from the command line to load OpenORB features. This class also provides several methods to access some information about configuration. For example, it is possible to call 'getBooleanProperty' to get a boolean value that corresponds to an OpenORB property ( stored into a profile ).
