Class PropertyBundle

java.lang.Object
org.zkoss.util.resource.PropertyBundle
public class PropertyBundle extends Object
The property bundle.

It is similar to java.util.ResourceBundle, but they differ as follows.

  • It uses Maps.load(Map, InputStream) to load the properties. Thus, It is capable to handle UTF-16 and UTF-8 (but not ISO-8859-1).
  • The locator could be any object as long as it implements InputStream getResourceAsStream(String).
  • It supports only property files.
  • The getBundle method returns null if the resource not found, while ResourceBundle throws MissingResourceException.

Instances of PropertyBundle are cached, so the performance is good. However, it implies the property file mapped by the giving class loader, name and locale is immutable. In other words, if you update the content of a property file, it might not be reflected to getString unless it is cleared out of the cache.

Thread safe.
