Field Detail

create_resp

protected CreateObjectResp create_resp

The result of the create, or null if the response is only tentative.

initial_vhash

protected SecureHash initial_vhash

The VHASH of the intial version of the object. In normal responses, this field is derived from create_resp. For tentative responses, this field is set and stored explicitly, because create_resp is null.
