Callback Object

Interface for ensuring a roundtrip to the EIS implementation. Clients can handle the ‘done’ event to get notified when the related request that created the ei_callback object is done.

Note that for a client to receive objects of this type, it must announce support for this interface in ei_handshake.interface_version.
