public void setFromServer(boolean v) {
    setEventFlag(EventFlags.FLAG_FROM_SERVER, v);
  }
Sets the fromServer flag to v. This must be set to true if an event comes from a server while
the affected region entry is not locked. Among other things it causes version conflict checks
to be performed to protect against overwriting a newer version of the entry.
