public EntityViewBuilder::buildMultiple(array $build_list)
Builds multiple entities' views; augments entity defaults.
This function is assigned as a #pre_render callback in ::viewMultiple().
By delaying the building of an entity until the #pre_render processing in drupal_render(), the processing cost of assembling an entity's renderable array is saved on cache-hit requests.
Parameters
array $build_list: A renderable array containing build information and context for an entity view.
Return value
array The updated renderable array.
