org.apache.struts.util.MessageResources
org.apache.struts.util.PropertyMessageResources
- All Implemented Interfaces:
- java.io.Serializable
- public class PropertyMessageResources
- extends MessageResources
Concrete subclass of MessageResources that reads message keys
and corresponding strings from named property resources in the same manner
that java.util.PropertyResourceBundle does. The
base property defines the base property resource name, and
must be specified.
IMPLEMENTATION NOTE - This class trades memory for
speed by caching all messages located via generalizing the Locale under
the original locale as well.
This results in specific messages being stored in the message cache
more than once, but improves response time on subsequent requests for
the same locale + key combination.

locales
protected java.util.HashMap locales
- The set of locale keys for which we have already loaded messages, keyed
by the value calculated in
localeKey().
log
protected static final org.apache.commons.logging.Log log
- The
Log instance for this class.
messages
protected java.util.HashMap messages
- The cache of messages we have accumulated over time, keyed by the
value calculated in
messageKey().
PropertyMessageResources
public PropertyMessageResources(MessageResourcesFactory factory,
java.lang.String config)
- Construct a new PropertyMessageResources according to the
specified parameters.
PropertyMessageResources
public PropertyMessageResources(MessageResourcesFactory factory,
java.lang.String config,
boolean returnNull)
- Construct a new PropertyMessageResources according to the
specified parameters.
getMessage
public java.lang.String getMessage(java.util.Locale locale,
java.lang.String key)
- Returns a text message for the specified key, for the default Locale.
A null string result will be returned by this method if no relevant
message resource is found for this key or Locale, if the
returnNull property is set. Otherwise, an appropriate
error message will be returned.
This method must be implemented by a concrete subclass.
- Specified by:
getMessage in class MessageResources
loadLocale
protected void loadLocale(java.lang.String localeKey)
- Load the messages associated with the specified Locale key. For this
implementation, the
config property should contain a fully
qualified package and resource name, separated by periods, of a series
of property resources to be loaded from the class loader that created
this PropertyMessageResources instance. This is exactly the same name
format you would use when utilizing the
java.util.PropertyResourceBundle class.
