The Client Code

The thin client uses the following files:

clientmain.cpp
ticketappclient.h
ticketappclient.cpp

clientmain.cpp

The client main program does the following:

Sets the router host and port
Creates an instance of TicketAppClient, which establishes a session with the ticketapp service
Creates an instance of TicketAppDisplay and runs it, which displays the main menu and starts the main processing loop
Handles all exceptions thrown by the client API, by catching oscs_Exception (and its descendents)

ticketappclient.h and ticketappclient.cpp

These files define two classes:

TicketAppClient
TicketAppDisplay

TicketAppClient defines a function for each operation (ListShows, ListPerformances, ViewSeats, BuySeats, and the administrative operations). Each function retrieves the corresponding ostc_ServerOperation, sets the arguments, executes the operation, and extracts the results.

The class TicketAppDisplay handles end-user I/O. It defines a function for each operation. Each item of the main menu invokes one of these functions. Each function takes input from the end user, passes it to the corresponding member of TicketAppClient, and outputs the results.
