Description
SmartClient has advanced features for queuing multiple requests in one single request. This provides a mechanism for sending multiple requests to the server in a single HTTP turnaround, thus minimizing network traffic as well as allowing the server to treat multiple requests as a single transaction (if the server is able to do so). In this sample the previous sample will be refactored to add support for queuing and transaction support.
In order to work with this transaction request, the code created in DSRequest in the previous article needs to be used. The existing code in RPCManager will need to be refactored. As the transaction request is actually a list of DSRequest objects wrapped with additional information, it is necessary to parse and store the list of DSRequest objects. Then, for each DSRequest object, the execute() method is called (as shown in the previous sample) to get the DSResponse object which will be stored in a list for later use. Once all requests are processed, the DSResponse objects will be used to build and send back the response to the front-end. As a side note, a single DSRequest will also be handled by the same code.
