This blog gives an introduction about various proxy design pattern implementation variant in Java and ABAP. Below paragraph is quoted directly from Wikipedia: “A proxy, in its most general form, is a class functioning as an interface to something else. The proxy could interface to anything: a network connection, a large object in memory, a file, or some other resource that is expensive or impossible to duplicate. In short, a proxy is a wrapper or agent object that is being called by the client to access the real serving object behind the scenes. Use of the proxy can simply be forwarding to the real object, or can provide additional logic. In the proxy extra functionality can be provided, for example caching when operations on the real object are resource intensive, or checking preconditions before operations on the real object are invoked. For the client, usage of a proxy object is similar to using the real object, because both implement the same interface.“ The UML diagram for Proxy Design pattern: I will first introduce various proxy implementation approaches in Java and then research whether these approaches could be simulated in ABAP as well. Java Proxy Design pattern – static proxy The example is very simple: an interface IDeveloper with only one method writeCode: public interface IDeveloper { public void writeCode(); } // An implementation class for this interface: public class Developer implements IDeveloper{ private String name; public Developer(String name){ this.name = name; } @Override public void writeCode() { System.out.println(\
