Recently I found out that C# allows for
For instance, the IScreen in Caliburn.Micro does this in http://caliburnmicro.codeplex.com/SourceControl/latest#src/Caliburn.Micro/IScreen.cs
namespace Caliburn.Micro
{
public interface IScreen : IHaveDisplayName, IActivate, IDeactivate,
IGuardClose, INotifyPropertyChangedEx
{
}
}I get why this is useful, as it implies that a class implementing IScreen also needs to implement the other interfaces.
But I wonder how the C# handles that compiler and run-time wise.
A little background/context of this question:
I come from a background where interfaces define a method-table, and that classes implementing interfaces have both their own method table, and pointers to the method tables of the interfaces they implement.
Sub questions swirling my mind stem from various multiple class inheritance discussions I had with people in the past, of which I think they apply to this case as well:
- Having an interface be able to inherit from multiple base interfaces, how would the order of methods in that table be?
- What if those interfaces have common ancestors: would those methods appear multiple times in the table?
- What if those interfaces have different ancestors, but similar method names?
(I’m using the word methods here, implying that a property defined in an interface will have a get_ or set_ method).
Any insight into this is much appreciated, as well as tips on how to phrase this question better.
