Code

public function getTargetBundles() {

  // If the reference field is using a view, load the view and see if it's filtering by the entity
  // type's bundle filter. If it is, the filter values are the target bundles. Otherwise,
  // assume that all bundles can be referenced.
  //
  // @todo Support contextual filters?
  //
  // NOTE: Selection handlers (i.e., $field['settings']['handler']) are plugins owned by
  // Entity Reference. There is no method defined to get an array of referenceable
  // bundles, but hopefully, if CER gains enough traction in the community, such a
  // method can be added to the EntityReference_SelectionHandler interface. This
  // function could then be deprecated, which would be a more flexible, future-proof
  // method of finding a field's target bundles.
