Class ResourceBundleWrapper

org.jfree.chart.util.ResourceBundleWrapper

public class ResourceBundleWrapper
extends Object

Wrapper of ResourceBundle.getBundle() methods. This wrapper is introduced to avoid a dramatic performance penalty by superfluous resource (and classes loaded by Class.forName) lookups on web server in applets.

 public class AppletC extends javax.swing.JApplet {
    public void init() {
       ResourceBundleWrapper.removeCodeBase(getCodeBase(),
               (URLClassLoader) getClass().getClassLoader());
    ...

Method Detail

removeCodeBase

public static void removeCodeBase(URL codeBase,
                  URLClassLoader urlClassLoader)

Instantiate a URLClassLoader for resource lookups where the codeBase URL is removed. This method is typically called from an applet's init() method. If this method is never called, the getBundle() methods map to the standard ResourceBundle lookup methods.

Parameters:

codeBase - the codeBase URL.

urlClassLoader - the class loader.

getBundle

public static ResourceBundle getBundle(String baseName)

Finds and returns the specified resource bundle.

Parameters:

baseName - the base name.

Returns:

The resource bundle.

getBundle

public static ResourceBundle getBundle(String baseName,
                       Locale locale)

Finds and returns the specified resource bundle.

Parameters:

baseName - the base name.

locale - the locale.

Returns:

The resource bundle.

getBundle

public static ResourceBundle getBundle(String baseName,
                       Locale locale,
                       ClassLoader loader)

Maps directly to ResourceBundle.getBundle(baseName, locale, loader).

Parameters:

baseName - the base name.

locale - the locale.

loader - the class loader.

Returns:

The resource bundle.
