Class RegistryOS

java.lang.Object
  org.biomoby.registry.properties.RegistryOS

public class RegistryOS
extends Object

This class delegates the responisiblity for obtaining system environment variables to other classes. The classes UNIX.java, Windows.java, etc, all implement this factory pattern and use the Singleton pattern.

Please note that this class attempts to mimic the functionality that was inherent in java up until java 1.4 and then brought back in java 5.0.

 public class MyOS implements Environment {
        public static final MyOS os = new MyOS();
 
        private MyOS() {
        }
 
        public Map getEnv() {
                // perform os specific code to get environment variables as key,value pairs
                // to put in a map
        }
 
        public static final void register() {
                RegistryOS.register("value obtained using jvm property 'os.name'", os);
        }
 }
 

Then just let RegistryOS know about your class, by putting a

 MyOS.register();
 

in the the static block of this class.

To use this class, on any supported OS, do the following:

 java.util.Map map = RegistryOS.getEnv();
 // lets retrieve the local registries url
 String server = (String) map.get("MOBY_SERVER");
