Annotation Interface ChenileParamType

@Retention(RUNTIME)
@Target(PARAMETER)
public @interface ChenileParamType

The ChenileParamType is required when the method signature of a service does not match the method signature of the controller. Chenile would not be able to determine the method of the service to call by reflection. The @ChenileParamType helps out by stating the correct param type of the actual service.

{ @Code
 public class ServiceImpl {
     public String foo(Object x){}
 } needs to be invoked by a controller which is defined here:

 public class Controller {
     public String Object(@ChenileParamType(Object.class) SomeClass x){
     }
 }
}

This situation can happen when the actual type in the Controller is a String whereas the param type expected is an Object (or some other base class). The actual type is determined by the BodyTypeSelector during runtime

Alternatively, there may be a situation when the same service class is reused multiple times. See chenile-workflow for an example. In this situation as well, the class will be of a more specific type in the Controller whilst it will be more generic in the Service class
