public class ResourceBundle

extends java.util.ResourceBundle

{link java.util.ResourceBundle} implementation using integers instead of strings for resource keys. Because it doesn't use strings, this implementation avoids adding all those string constants to files and runtime images. Developers still have meaningful labels in their code (e.g. ) through a set of constants defined in interfaces. This approach furthermore gives the benefit of compile-time safety. Because integer constants are inlined right into class files at compile time, the declarative interface is never loaded at run time. This class also provides facilities for string formatting using MessageFormat.

Constructor Detail

ResourceBundle

protected ResourceBundle()

Constructs a new resource bundle. The resource filename will be inferred from the fully qualified classname of this subclass.

Since:

2.2

ResourceBundle

protected ResourceBundle(java.lang.String filename)

Constructs a new resource bundle.

Parameters:

filename - The resource name containing resources. It may be a filename or an entry in a JAR file.

Method Detail

list

public final void list(java.io.Writer out)
                throws java.io.IOException

Lists resources to the specified stream. If a resource has more than one line, only the first line will be written. This method is used mostly for debugging purposes.

Parameters:

out - The destination stream.

Throws:

java.io.IOException - if an output operation failed.

getKeys

public final java.util.Enumeration getKeys()

Returns an enumeration of the keys.

handleGetObject

protected final java.lang.Object handleGetObject(java.lang.String key)

Gets an object for the given key from this resource bundle. Returns null if this resource bundle does not contain an object for the given key.

Parameters:

key - the key for the desired object

Returns:

the object for the given key, or null

Throws:

java.lang.NullPointerException - if is

getMenuLabel

public final java.lang.String getMenuLabel(int key)
                                    throws java.util.MissingResourceException

Gets a string for the given key and appends "..." to it. This method is typically used for creating menu items.

Parameters:

key - The key for the desired string.

Returns:

The string for the given key.

Throws:

java.util.MissingResourceException - If no object for the given key can be found.

getLabel

public final java.lang.String getLabel(int key)
                                throws java.util.MissingResourceException

Gets a string for the given key and appends ": " to it. This method is typically used for creating labels.

Parameters:

key - The key for the desired string.

Returns:

The string for the given key.

Throws:

java.util.MissingResourceException - If no object for the given key can be found.

getString

public final java.lang.String getString(int key)
                                 throws java.util.MissingResourceException

Gets a string for the given key from this resource bundle or one of its parents.

Parameters:

key - The key for the desired string.

Returns:

The string for the given key.

Throws:

java.util.MissingResourceException - If no object for the given key can be found.

getString

public final java.lang.String getString(int key,
                                        java.lang.Object arg0)
                                 throws java.util.MissingResourceException

Gets a string for the given key and formats it with the specified argument. The message is formatted using MessageFormat. Calling this method is approximately equivalent to calling:

   String pattern = getString(key);
   Format f = new MessageFormat(pattern);
   return f.format(arg0);
 

If is not already an array, it will be placed into an array of length 1. Using MessageFormat, all occurrences of "{0}", "{1}", "{2}" in the resource string will be replaced by , , , etc.

Parameters:

key - The key for the desired string.

arg0 - A single object or an array of objects to be formatted and substituted.

Returns:

The string for the given key.

Throws:

java.util.MissingResourceException - If no object for the given key can be found.
