I always see objectmanager instantiated by objectmanagerinterface. But I never found di.xml that have preference of objectmanagerinterface to objectmanager.

Is it something I have never found? Or is objectmanager some special object that doesn't need di.xml?

Refer to this line from the object manager class:


There is somewhere (not sure exactly where), but really early in the application a call to instantiate the Object manager class (not referred via interface), and when the OM gets instantiated it adds the mapping from the interface to itself.

  • Wow so objectmanager is actually a special object treated by object manager. Thanks! May 7, 2019 at 13:45
