Hi there,
The issue IOC-ISSUE-144 was just created by Jo?o Bragan?a (captainramen).
Key: IOC-ISSUE-144
Summary: Cannot Register Abstract Components With Interceptor as of
r5530
Type: Bug
Importance: Low
Description:
I think DefaultComponentActivator should make an exception for abstract
components that have interceptors set on them. Example:
public abstract class Scale
{
public virtual bool IsOn { get; set; }
public virtual double Weight { get; set; }
}
public class DataBindingInterceptor
: IInterceptor
{
protected PropertyChangedEventHandler propertyChanged = delegate { };
#region IInterceptor Members
public void Intercept(IInvocation invocation)
{
if (invocation.Method.DeclaringType ==
typeof(INotifyPropertyChanged))
{
var handler =
(PropertyChangedEventHandler)invocation.Arguments[0];
if (invocation.Method.Name.StartsWith("add_"))
{
propertyChanged += handler;
}
else
{
propertyChanged -= handler;
}
invocation.ReturnValue = null;
return;
}
Invoke(invocation);
RaiseIfRequired(invocation, invocation.Proxy);
}
#endregion
private void RaiseIfRequired(IInvocation invocation, object target)
{
if (invocation.Method.Name.StartsWith("set_"))
{
propertyChanged(target, new
PropertyChangedEventArgs(invocation.Method.Name.Substring(4)));
}
}
protected virtual void Invoke(IInvocation invocation)
{
invocation.Proceed();
}
}
static void Main()
{
Kernel.Register(Component.For<DataBindingInterceptor>().Named("dataBindingInterceptor").LifeStyle.Transient);
Kernel.Register(Component.For<Scale>()
.Interceptors(new
InterceptorReference("dataBindingInterceptor")).Anywhere
.Proxy.AdditionalInterfaces(typeof
(INotifyPropertyChanged)));
}
