Method startTransfer

core/CBRConnection.java:45–62

Sets a message that this connection is currently transferring. If message passing is controlled by external events, this method is not needed (but then e.g. #finalizeTransfer() and #isMessageTransferred() will not work either). Only a one message at a time can be transferred using on
