51Degrees Device Detection Java  4.4

Device detection services for 51Degrees Pipeline

hash/StronglyTyped.java

Strongly typed example using 51Degrees Device Detection 'Hash' engine.

This example is available in full on GitHub.

This example requires a local data file. The free 'Lite' data file can be acquired by pulling the git submodules under this repository (run `git submodule update --recursive`) or from the device-detection-data GitHub repository.

The Lite data file is only used for illustration, and has limited accuracy and capabilities. Find out about the more capable data files that are available on our pricing page
