[ninf-users:00134] Re: object handle

[Yoshio Tanaka <yoshio.tanaka@aist.go.jp>]

Hi,

In your example, Ninf-G remote object (O_B) is created on host B by
calling grpc_object_handle_init_np() on host A.  O_B does exist on
host B and can be referred by an object handle created on host A.

I'm not sure what "serialized" mean, but the object handle is a C
structure and kept in a variable on host A.  Thus, the object handle
is not valid on host C and no handles on host C could invoke
methods of O_B which was created on host A.

Regards,
