Class LocalizedMessage

java.lang.Object
  org.apache.logging.log4j.message.LocalizedMessage

All Implemented Interfaces:

Serializable, LoggerNameAwareMessage, Message

public class LocalizedMessage
extends Object
implements Message, LoggerNameAwareMessage

Provides some level of compatibility with Log4j 1.x and convenience but is not the recommended way to Localize messages.

The recommended way to localize messages is to log a message id. Log events should then be recorded without formatting into a data store. The application that is used to read the events and display them to the user can then localize and format the messages for the end user.

Method Detail

setLoggerName

public void setLoggerName(String name)

Set the name of the Logger.

Specified by:

setLoggerName in interface LoggerNameAwareMessage

Parameters:

name - The name of the Logger.

getLoggerName

public String getLoggerName()

Returns the name of the Logger.

Specified by:

getLoggerName in interface LoggerNameAwareMessage

Returns:

the name of the Logger.

getFormattedMessage

public String getFormattedMessage()

Returns the formatted message after looking up the format in the resource bundle.

Specified by:

getFormattedMessage in interface Message

Returns:

The formatted message String.

getFormat

public String getFormat()

Description copied from interface: Message

Gets the format portion of the Message.

Specified by:

getFormat in interface Message

Returns:

The message format. Some implementations, such as ParameterizedMessage, will use this as the message "pattern". Other Messages may simply return an empty String. TODO Do all messages have a format? What syntax? Using a Formatter object could be cleaner. (RG) In SimpleMessage the format is identical to the formatted message. In ParameterizedMessage and StructuredDataMessage it is not. It is up to the Message implementer to determine what this method will return. A Formatter is inappropriate as this is very specific to the Message implementation so it isn't clear to me how having a Formatter separate from the Message would be cleaner.

getParameters

public Object[] getParameters()

Description copied from interface: Message

Gets parameter values, if any.

Specified by:

getParameters in interface Message

Returns:

An array of parameter values or null.

getThrowable

public Throwable getThrowable()

Description copied from interface: Message

Gets the throwable, if any.

Specified by:

getThrowable in interface Message

Returns:

the throwable or null.

getResourceBundle

protected ResourceBundle getResourceBundle(String rbBaseName,
                                           Locale resourceBundleLocale,
                                           boolean loop)

Override this to use a ResourceBundle.Control in Java 6

Parameters:

rbBaseName - The base name of the resource bundle, a fully qualified class name.

resourceBundleLocale - The locale to use when formatting the message.

loop - If true the key will be treated as a package or class name and a resource bundle will be located based on all or part of the package name. If false the key is expected to be the exact bundle id.

Returns:

The ResourceBundle.
