openlibs.i18n

The lib of java internationalization, includes resource bundle and db implementation.

###Get it by Maven

<dependency>
  <groupId>com.openthinks.libs</groupId>
  <artifactId>utilities</artifactId>
  <version>1.0</version>
</dependency>

@see http://daileyet.github.io/openlibs.i18n.

###Quick useage for the implementation java.util.ResourceBundle: #####1. Directly use pack name

//resource pack dir and pack name; 
//put your resource bundle file Log.properties 
//under your project path "openthinks/libs/i18n/resource/i18n/"
String BASE_PACK_DIR = "openthinks/libs/i18n/resource/i18n/";
String LOG_PACK_NAME = "Log";
//get internationalization message by the properties key in bundle properties file
//get default locale message
String message = I18n.getMessage(BASE_PACK_DIR + LOG_PACK_NAME, "1000");
//get special locale message
message = I18n.getMessage(BASE_PACK_DIR + LOG_PACK_NAME,Locale.UK, "1000");

#####2. Use customized IBundleMessageType

//define a customized message type, here is a enum;
//it also can be normal class just implement interface IBundleMessageType
public enum CustomizedMessageType implements IBundleMessageType{
	LOG, EXCEPTION, UI;
	@Override
	public String value() {
		return name() + ":" + BASE_PACK_DIR + name();
	}
	@Override
	public String getPackName() {
		//openthinks/libs/i18n/resource/i18n/LOG
		//openthinks/libs/i18n/resource/i18n/EXCEPTION
		//openthinks/libs/i18n/resource/i18n/UI
		return BASE_PACK_DIR + name();
	}
	@Override
	public String getMessageType() {
		return name();
	}
public static final String BASE_PACK_DIR = "openthinks/libs/i18n/resource/i18n/"; 

}
//get default locale message
String message = I18n.getMessage(CustomizedMessageType.LOG, "1000");
//get special locale message
message = I18n.getMessage(CustomizedMessageType.LOG,Locale.UK, "1000");

### Locale change in application ###### Use class I18nApplicationLocale

//example for Swing UI, make it as Observer and regiester to I18nApplicationLocale
class UI extends JFrame implements Observer{
 		private JButton button;
 		private JLabel label;
	public UI(){
		//initialize component
		//register to I18nApplicationLocale
		I18nApplicationLocale.getInstance().addObserver(this);
	}
	
	// Overrides Observer
	public void update(Observable o, Object argument) {
		setLocaleMessage();
	}
	
	public void setLocaleMessage(){
		button.setText(I18n.getMessage(CustomizedMessageType.UI,"2000"));
		label.setText(I18n.getMessage(CustomizedMessageType.UI,"2001"));
	}

}
// when the application locale changed, call the following statement
I18nApplicationLocale.getInstance().changeCurrentLocale(Locale.UK);
