Castle windsor interceptor using a method that calls another method

Question

---

interceptor

public class CachingInterceptor : IInterceptor { public void Intercept(IInvocation invocation) { // code comes here.... } } 

---

Business level

 public class Business : IBusiness { public void Add(string a) { var t= GetAll(); // code comes here.... } [CacheAttribute] public string GetAll() { // code comes here.... } } 

---

Class

 public class JustForTest { public JustForTest(IBusiness business) { //if GetAll is invoked directly caching works fine. business.GetAll(); //if GetAll is invoked over Add method caching doesn't work. business.Add(); } } 

The add method calls the GetAll method. If I call the GetAll method directly, caching works. If the Add method calls the GetAll method, caching does not work.

Thanks for the help.

Answer 1

Proxy interfaces are created by moving the proxy target, so this is not possible with interfaces.

You can intercept calls of the same objects, but only for a proxy class (provided that the method is virtual). See the answer to a similar question .

You can also try to structure your code in different ways, move the logic that needs to be cached for services that can be cached without using their own functions.

Answer 2

The problem is that the line

 var t= GetAll(); 

inside the class Business . It can be more clearly written as

 var t = this.GetAll(); 

this not an intercepted / wrapped instance.

Try to separate the responsibilities of the Business class as suggested here and here.
