It seems like you code against a specific sub-type and not the parent class mcorten87\rabbitmq_api\jobs\JobBase as the method getVirtualHost() does only exist in the following sub-classes of mcorten87\rabbitmq_api\jobs\JobBase: mcorten87\rabbitmq_api\jobs\JobExchangeCreate, mcorten87\rabbitmq_api\jobs\JobExchangeDelete, mcorten87\rabbitmq_api\jobs\JobExchangeList, mcorten87\rabbitmq_api\j...ExchangeListVirtualHost, mcorten87\rabbitmq_api\jobs\JobPermissionCreate, mcorten87\rabbitmq_api\jobs\JobPermissionDelete, mcorten87\rabbitmq_api\j...rmissionListVirtualHost, mcorten87\rabbitmq_api\jobs\JobQueueCreate, mcorten87\rabbitmq_api\jobs\JobQueueDelete, mcorten87\rabbitmq_api\jobs\JobQueueList, mcorten87\rabbitmq_api\j...JobQueueListVirtualHost, mcorten87\rabbitmq_api\jobs\JobVirtualHostCreate, mcorten87\rabbitmq_api\jobs\JobVirtualHostDelete, mcorten87\rabbitmq_api\jobs\JobVirtualHostList. Maybe you want to instanceof check for one of these explicitly?

Let’s take a look at an example:

abstract class User
{
    /** @return string */
    abstract public function getPassword();
}

class MyUser extends User
{
    public function getPassword()
    {
        // return something
    }

    public function getDisplayName()
    {
        // return some name.
    }
}

class AuthSystem
{
    public function authenticate(User $user)
    {
        $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName()));
        // do something.
    }
}

In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different sub-classes of User which does not have a getDisplayName() method, the code will break.

Available Fixes

  1. Change the type-hint for the parameter:

    class AuthSystem
    {
        public function authenticate(MyUser $user) { /* ... */ }
    }
    
  2. Add an additional type-check:

    class AuthSystem
    {
        public function authenticate(User $user)
        {
            if ($user instanceof MyUser) {
                $this->logger->info(/** ... */);
            }
    
            // or alternatively
            if ( ! $user instanceof MyUser) {
                throw new \LogicException(
                    '$user must be an instance of MyUser, '
                   .'other instances are not supported.'
                );
            }
    
        }
    }
    
Note: PHP Analyzer uses reverse abstract interpretation to narrow down the types inside the if block in such a case.
  1. Add the method to the parent class:

    abstract class User
    {
        /** @return string */
        abstract public function getPassword();
    
        /** @return string */
        abstract public function getDisplayName();
    }
