ActivityPubValidateActivityStreamsTwoData: To extend an Activity properties that we are managing from JSON

  • @param string $type_name When we handle a Type, we will send you the type identifier of the one being handleded
  • @param array &$validators attribute => Validator the array key should have the attribute name that you want to hand, the value should be a validator class
  • @return Returns Event::next

Example:

public function onActivityPubValidateActivityStreamsTwoData(string $type_name, array &$validators): bool {
    if ($type_name === '{Type}') {
        $validators['attribute'] = myValidator::class;
    }
    return Event::next;
}

The Validator should be of the form:

class myValidator extends \Plugin\ActivityPub\Util\ModelValidator
{
    /**
     * Validate Attribute's value
     *
     * @param mixed $value from JSON's attribute
     * @param mixed $container A {Type}
     * @return bool
     * @throws Exception
     */
    public function validate($value, $container): bool
    {
        // Validate that container is a {Type}
        \ActivityPhp\Type\Util::subclassOf($container, \ActivityPhp\Type\Extended\Object\{Type}::class, true);

        return {Validation Result};

ActivityPubAddActivityStreamsTwoData: To add attributes to an entity that we are managing to JSON (commonly federating out via ActivityPub)

  • @param string $type_name When we handle a Type, we will send you the type identifier of the one being handled
  • @param \ActivityPhp\Type\AbstractObject &$type_activity The Activity in the intermediate format between Model and JSON
  • @return Returns Event::next

ActivityStreamsTwoContext: To expand our ActivityStreams 2 Context

  • @param array &$activity_streams_two_context Append to the array your additional context
  • @return Returns Event::next

ActivityPubActivityStreamsTwoResponse: To add a route to ActivityPub (the route must already exist in your plugin) (commonly being requested to ActivityPub)

  • @param string $route Route identifier
  • @param array $vars From your controller
  • @param \Plugin\ActivityPub\Util\TypeResponse &$response The JSON (protip: ModelResponse's handler will convert entities into TypeResponse)
  • @return Returns Event::stop if handled, Event::next otherwise

Example:

public function onActivityPubActivityStreamsTwoResponse(string $route, arrray $vars, ?TypeResponse &$response = null): bool {
        if ($route === '{Object route}') {
                $response = \Plugin\ActivityPub\Util\ModelResponse::handle($vars[{Object}]);
                return Event::stop;
        }
        return Event::next;
}

  • @param Actor $actor Actor who authored the activity
  • @param \ActivityPhp\Type\AbstractObject $type_activity Activity
  • @param \ActivityPhp\Type\AbstractObject $type_object Object
  • @param ?\Plugin\ActivityPub\Entity\ActivitypubActivity &$ap_act ActivitypubActivity
  • @return Returns Event::stop if handled, Event::next otherwise

NewActivityPubActivityWithObject: To convert an Activity Streams 2.0 formatted activity with a known object into Entities (commonly when we receive a JSON in our inbox)

  • @param Actor $actor Actor who authored the activity
  • @param \ActivityPhp\Type\AbstractObject $type_activity Activity
  • @param Entity $type_object Object
  • @param ?\Plugin\ActivityPub\Entity\ActivitypubActivity &$ap_act ActivitypubActivity
  • @return Returns Event::stop if handled, Event::next otherwise

GSVerbToActivityStreamsTwoActivityType: Translate a GNU social internal verb to an Activity Streams 2.0 one

  • @param string $verb GNU social's internal verb
  • @param \ActivityPhp\Type\AbstractObject &$gs_verb_to_activity_stream_two_verb Activity Streams 2.0 verb
  • @return Returns Event::stop if handled, Event::next otherwise

Example:

public function onGSVerbToActivityStreamsTwoActivityType(string $verb, ?string &$gs_verb_to_activity_stream_two_verb): bool
{
    if ($verb === '{GS verb}') {
        $gs_verb_to_activity_stream_two_verb = '{AS2 verb}';
        return Event::stop;
    }
