ReservationRequestGenerator

public ReservationRequestGenerator()
                            throws java.io.IOException

Create an object that generates ReservationRequests using the default set of built-in names for input.

If the system property "infoRequests" is set, the resulting ReservationRequestGenerator will enable a mechanism to make information requests back to Flight and Reservation objects previously generated.

System property values can be set on the java command line:

 java -DinfoRequests=true ...

public ReservationRequestGenerator(java.net.URL url)
                            throws java.io.IOException

Create an object that generates ReservationRequests using the indicated URL as the source of names.
