function hook_uninstall in Zircon Profile 8

Same name and namespace in other branches

1. 8.0 core/lib/Drupal/Core/Extension/module.api.php \hook_uninstall()

Remove any information that the module sets.

The information that the module should remove includes:

• state that the module has set using \Drupal::state()
• modifications to existing tables

The module should not remove its entry from the module configuration. Database tables defined by hook_schema() will be removed automatically.

The uninstall hook must be implemented in the module's .install file. It will fire when the module gets uninstalled but before the module's database tables are removed, allowing your module to query its own tables during this routine.
