What's Covered

This tutorial illustrates how to return a match for a Device Id. It shows how to first get the Device Id from a match, then get a match for that Device Id and return the value of the IsMobile property. This can be useful to look at devices that have already been matched at a previous date.

Code and Explanation

Match for device id example of using 51Degrees device detection. The example shows how to:

  1. Set the various settings for 51Degrees detector 

    												
my $filename = "51Degrees-LiteV3.2.dat";
my $propertyList = "IsMobile"
my $cacheSize = 10000;
my $poolSize = 20;

  • Instantiate the 51Degrees device detection provider with these properties 

    									
my $provider = new FiftyOneDegrees::PatternV3::Provider(
	$dataFile,
	$properties,
	$cacheSize,
	$poolSize);
  • Produce a match for a single device id 

    									
my $match = $provider->getMatchForDeviceId($userAgent)
  • Extract the value of the IsMobile property 

    									
$match->getValue('IsMobile')
    This example assumes you are running from the original subdirectory i.e. Device-Detection/perl/examples/ and the 51Degrees Perl module is installed.

    • Summary

    In this tutorial you have seen how to use the detector to retrieve the IsMobile property for a pre-defined Device ID string. The example can easily be modified to retrieve the value of any other property. Premium and Enterprise data files provide considerably more properties such as IsCrawler , PriceBand , HardwareVendor and ScreenInchesWidth . For a full list of properties and the data files they exist in please see the Property Dictionary .
