I have found some examples how to create an interceptor, for instance
this http://robtennyson.us/post/2009/08/23/NHibernate-Interceptors.aspx
but what I really want to do is to setup when the interception should
happen kinda like this
public bool ShouldInterceptMethod(Type type, MethodInfo memberInfo)
{ return
(memberInfo.IsGetterOrSetterForPropertyWithAttribute(typeof(SomeAttribute))); }
and then in the interception method i would return the value from the
detailscollection kinda like this
public void Intercept(IInvocation invocation)
2: {
3: TypedPageData invocationTarget = (TypedPageData)
invocation.InvocationTarget;
4: string propertyName = invocation.Method.GetPropertyName();
5: if (invocation.Method.IsGetter())
6: {
7: invocation.ReturnValue = invocationTarget[propertyName];
8: if ((invocation.ReturnValue == null) &&
(invocation.Method.ReturnType == typeof(bool)))
9: {
10: invocation.ReturnValue = false;
11: }
12: }
13: else
14: {
15: invocationTarget.SetValue(propertyName,
invocation.Arguments[0]);
16: }
17: }
any pointers on that?
