A fast User Agent parser library, using data from udger.com

Maven Dependency

<dependency>
  <groupId>me.atlis</groupId>
  <artifactId>decibelinsight-uasparser</artifactId>
  <version>RELEASE</version>
</dependency>

Usage

Simply use DIUASparser or any of its subclasses like so:

UASparser parser = new UASparser();
String key = ""; // udger license key
OnlineUpdater updater = new OnlineUpdater(parser, key);
UserAgentInfo info = parser.parse("Mozilla/4.0 (compatible; MSIE 7.0;Windows NT 5.1; )");

This will create a new parser and initialize it with a bundled copy of the database. The OnlineUpdater will then asynchronously fetch the latest database in the background, making it available after a few seconds and caching it locally as well. See it's source for more on how it works.

In addition, there are a few different parser classes available:

• UASparser - Default parser, thread-safe
• MultithreadedUASparser - A faster variant of UASparser, uses a bit more memory
• SingleThreadedUASparser - Non-threadsafe variant, ideal for Hadoop and similar use cases
• BrowserFamilyParser - UASparser subclass which only returns the browser family string

Dependencies

• JRegex
