How to get the fields of the entity?

Question

I need to get all the names of the entity, my entity is called 'a_process'? How can I write such query in Drupal 8?

$nodes = entity_load_multiple('a_process', $name);

Answer 1

You can use the entity type manager to load entities of any type:

$entities = \Drupal::entityTypeManager()
  ->getStorage('a_process')
  ->loadMultiple();

foreach ($entities as $entity) {
  // ...
}

If your code is in a container aware context, be sure to inject the entity manager as a service instead of referring to \Drupal explicitly.

Of course if you always know the entity type up-front you can use the method on the entity class itself, eg

$entities = \Drupal\foo\Entity\AProcess::loadMultiple()
