class DisplayManager in Examples for Developers 3.x

Same name and namespace in other branches
  1. 8 phpunit_example/src/DisplayManager.php \Drupal\phpunit_example\DisplayManager

An example class to demonstrate unit testing.

Think of this class as a class that collects DisplayInfoInterface objects, because that's what it is. It also might go on to one day display lists of info about these info objects.

But it never will, because it's just an example class.

Part of the PHPUnit Example module.
