interface FeaturesGeneratorInterface in Features 8.4

Common interface for features generation services.

The configuration packaging API is based on two major concepts:

• Packages: modules into which configuration is packaged.
• Package generation methods: responsible for `determining which package to assign a given piece of configuration to.

Generation methods are customizable.

Features defines two package generation methods, which are simple plugin classes that implement a particular logic to assign pieces of configuration to a given package (module).

Modules can define additional package generation methods by simply providing the related plugins, and alter existing methods through hook_features_generation_method_info_alter(). Here is an example snippet:

function mymodule_features_generation_method_info_alter(&$generation_info) {

  // Replace the original plugin with our own implementation.
  $method_id = \Drupal\features\Plugin\FeaturesGeneration\FeaturesGenerationArchive::METHOD_ID;
  $generation_info[$method_id]['class'] = 'Drupal\\my_module\\Plugin\\FeaturesGeneration\\MyFeaturesGenerationArchive';
}
class MyFeaturesGenerationArchive extends FeaturesGenerationArchive {
  public function generate(array $packages = array(), FeaturesBundleInterface $bundle = NULL) {

    // Insert customization here.
  }

}
?>
?><?php
