RemObjects Client: Calling Server Methods

1. In the RemObjects client, the first step is to create a service proxy object to remotely call the server-side interface. This proxy object is responsible for establishing a connection with the server and encapsulating the methods for communication with the server.
2. Call the server-side interface by using a service proxy object. These methods typically correspond one-to-one with the methods of the server-side interface and can be directly called from the client. For example, if the server-side interface has a method called “getData”, then the client can use the “getData” method of the service proxy object to call that interface.
3. When calling a method of a service proxy object, the parameters are passed to the server interface, and the server’s response is awaited. This process takes place over the network, thus there may be some latency.
4. After the server receives the client’s request, it will execute the corresponding method and return the results to the client.
5. After receiving the results returned by the server, the client can process them according to their needs. For example, they can display the results on the interface or carry out other business logic processing.

In conclusion, the process of RemObjects client invoking server interface includes steps such as establishing a connection, calling a method, passing parameters, waiting for results, and handling the results. This process can be done in the client’s code, using the service proxy object.
