php - REST API wrapper design -

i'm writing wrapper (adapter pattern) number of rest calls. i'm trying decide how response object should able do.

class job {     private $xml;     public function __construct(simplexmlelement  $xml)     {         $this->xml = $xml;     }     public function getname()     {         return $this->xml->name;     }     public function getid()     {         return $this->xml->id;     }     ...     ...     ... }  class restmanager {     private $client;     public function __construct(guzzle $client)     {          $this->client = $client     }     public function getjobbyname($name)     {          $job = $this->client->get('/query/job/' . $name);          return new job($job->asxmlobj())     } } 

so have similar above. once have job object want additional information such as, list of items in job. requires server call should ask job items

class job {     private $manager;     ...     ...     public function addmanager(restmanager $manager)     {          $this->manager = $manager;     }     public function getitems()     {          return $this->manager->getjobitems($this);     } } 

or ask restmanager directly?

class restmanager {     ...     ...     public function getjobitems(job $job)     {         return $this->client->get('/job/' . $job->getid() . '/items');     } }
