public function GroupRelationManager::createHandlerInstance in Group 2.0.x

Creates a new handler instance.

Using ::getHandler() is preferred since that method has static caches.

@internal Marked as internal because the plugin definitions will become classes in a future release to further mimic the entity type system. Do not call this directly.

Parameters

string $plugin_id: The plugin ID for this handler.

string $handler_type: The handler type to create an instance for.

Return value

object A handler instance.
