public abstract class OpenListResourceBundle
extends ResourceBundle

Subclass of ResourceBundle which mimics ListResourceBundle, but provides more hooks for specialized subclass behavior. For general description, see ListResourceBundle.

This class leaves handleGetObject non-final, and adds a method createMap which allows subclasses to use specialized Map implementations.

Method Detail

handleGetObject

public Object handleGetObject(String key)

Description copied from class: ResourceBundle

Override this method to provide the resource for a keys. This gets called by getObject. If you don't have a resource for the given key, you should return null instead throwing a MissingResourceException. You don't have to ask the parent, getObject() already does this; nor should you throw a MissingResourceException.

getKeys

Specified by:

getKeys in class ResourceBundle

Returns:

an enumeration of the keys

handleGetKeys

public Set<String> handleGetKeys()

Returns a set of keys provided in this resource bundle

getParent

public OpenListResourceBundle getParent()

Returns the parent bundle

getContents
