DESCRIPTIONThis class is used as a message-passing interface by the RPC service modules.
PROPERTIESThese properties should be filled in by the initiating caller
- method_name => Text
- The name of the subroutine the initiator whishes to call.
- target_class => Text
- The namespace the initiator wants the subroutine to be called in
- params => ARRAY
- List of parameters to pass to the subroutine
- wantarray => Boolean
- What wantarray() context the subroutine should be called in.
These properties are assigned after the RPC call to the subroutine
- return_values => ARRAY
- List of values returned by the subroutine
- On the receiving side, the subroutine is called within an eval. If there was an exception, "exception" stores the value of $@, or the empty string. The receiving side should also fill-in "exception" if there was an authentication failure.
- "recv" fills this in with the file handle the message was read from.
$bytes = $msg->send($fh);
Serializes the Message object with FreezeThaw and writes the data to the filehandle $fh. Returns the number of bytes written. $bytes will be false if there was an error.
$response = UR::Service::RPC::Message->recv($fh,$timeout); $response = $msg->recv();
Reads a serialized Message from the filehandle and constructs a Message object that is then returned to the caller. In the first case, it reads from the given filehandle, waiting a maximum of $timeout seconds with select before giving up. In the second case, it reads from whatever filehandle is stored in $msg to read data from.
