Examples of hudson.remoting.VirtualChannel.call()

hudson.remoting.VirtualChannel.call()

            w.println("Master to slave");
            ((Channel)vc).dumpExportTable(w);
            w.flush(); // flush here once so that even if the dump from the slave fails, the client gets some useful info


            w.println("\n\n\nSlave to master");
            w.print(vc.call(new DumpExportTableTask()));
        } else {
            w.println(Messages.Computer_BadChannel());
