Re: [Jsdsi-users] Re: <What's the correct way to send over Proof?>

[Sameer A. <aj...@cs...>]

To clarify:

Client:
    FileOutputStream pd_file_out = new
FileOutputStream("server_agent_queue.txt",
true);
    jsdsi.sexp.ObjOutputStream pd_oos = new
jsdsi.sexp.ObjOutputStream(pd_file_out);
==> pd_oos.writeCanonical(proof.getSequence());
    pd_file_out.close();

 Server:
    FileInputStream file_in = new FileInputStream("server_agent_queue.txt");
    jsdsi.sexp.ObjInputStream ois = new jsdsi.sexp.ObjInputStream(fis);
    while (true) {
          if (ois.available() > 0) {
==>         jsdsi.Proof pf = new Proof (Certificate.fromSequence
((jsdsi.Sequence) ois.readObj()));
            break;
          }
        }

This is another case where a better API is needed.  Any suggestions? 
Probably the most sensible is just to make the way you wanted to use it
(Obj.parseObj()) work, i.e., provide Proof.parseProof().
