maybe this is easy, but searching it on the internet already give me a head ache
here is the problem:
interface IValidator
{
void Validate(object obj);
}
public class ValidatorA : IValidator
{
public void Validate(object obj) { }
}
public class ValidatorB : IValidator
{
public void Validate(object obj) { }
}
interface IClassA { }
interface IClassB { }
public class MyBaseClass
{
protected IValidator validator;
public void Validate()
{
validator.Validate(this);
}
}
public class ClassA : MyBaseClass, IClassA
{
//problem: validator should ValidatorA
public ClassA(IValidator validator) { }
}
public class ClassB : MyBaseClass, IClassB
{
//problem: validator should ValidatorB
public ClassB(IValidator validator) { }
}
public class OtherClass
{
public OtherClass(IClassA a, IClassB b) { }
}
//on Main
var oc = container.Resolve<OtherClass>();
Any idea?
EDIT
I registered ValidatorA
and ValidatorB
with Named
, now the problem how Castle Windsor can inject those validator properly to the ClassA
and ClassB
, is there a way to do that? or is there any better solution?
if there is someone think my class design is wrong please, i open for any advice. So far i think it correct. Yes, validator have specific configuration for specific Class. but there are reasons it is abstracted:
- Validator is a complex object, sometime should connect to database, so I MUST pass interface instead of implementation to constructor for unit testing reason.
- No way to use different interface for any of Validator, because the only method that i used is
Validate
- I think
MyBaseClass.Validate()
a common template method pattern isn't it?
