[jira] Updated: (LANG-362) Add ExtendedMessageFormat to org.apache.commons.lang.text

["Niall Pemberton (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LANG-362?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Niall Pemberton updated LANG-362:
---------------------------------

    Attachment: DateFormatFactory.java
                FormatFactory.java
                ExtendedMessageFormat2.java

OK I'm attaching the following implementations

 - ExtendedMessageFormat2
 - FormatFactory
 - DateFormatFactory

The DateFormatFactory is an example FormatFactory implementation that supports the existing "date" and "time" format types, but also adds a new "datetime" type. (btw its written as it is so that it can be used to implement Lang's FastDateFormat implementation - by just overriding the protected methods).

So to use the new "datetime" type, all thats required is the following:

        Map registry = new HashMap();
        registry.put("datetime", new DateFormatFactory());

        String pattern = "Date: {0,date,short} Time: {0,time,medium} Date/Time: {0,datetime,long}";
        ExtendedMessageFormat2 fmt = new ExtendedMessageFormat2(pattern, registry);

        System.out.println(fmt.format(new Object[] {new Date()}));

Note that the "date" and "time" types are not being handled by our custom factory - the standard MessageFormat functionality is doing that. If we wanted we could register custom formats for those standard types as well.

Maybe I'm missing something, but is this not achieving the same goal?
