fresh off of my last error mail to the list, here's another fun one:
public interface ISomeInterface:
Id as int:
get
public class ConstraintChaining:
public def InnerMethod[of T(ISomeInterface)](foo as T) as int:
return foo.Id;
public def OutterMethod[of T(ISomeInterface)](foo as T) as int:
return InnerMethod[of T](foo)
gives us:
The type 'T' must derive from 'Sandbox.ISomeInterface' in order to
substitute the generic parameter 'T' in
'Sandbox.ConstraintChaining.InnerMethod[of T](T)'. (BCE0149) -
C:\Users\Administrator\Documents\SharpDevelop
Projects\Sandbox\ConstraintsTest.boo:28,23
the error is on the return statement in OutterMethod[of T]()
the corresponding code in C# compiles:
public interface ISomeInterface {
int Id {
get; set;
}
}
public class ConstraintChaining {
public int InnerMethod<T>(T foo) where T : ISomeInterface
{
return foo.Id;
}
public int OutterMethod<T>(T foo) where T : ISomeInterface
{
return InnerMethod<T>(foo);
}
}
cheers
