Looking for properties to tamper with.

MaybeTamperWith.cs

  return _typeDef.IsClass 
    && HasPropertiesToTamperWith() 
    && ReallyTamperWith();
}

private bool HasPropertiesToTamperWith()

}

private void FindPropertiesToTamperWith()

  var isViewableType = IsViewable(_typeDef);
  foreach (var prop in _typeDef.Properties
    .Where(p => IsViewable(p) || (isViewableType && !IsOpaque(p))))
  {
    HandlePropertyToNotify(prop);
  }
}

private static bool IsViewable(ICustomAttributeProvider item)
{
  return HasAttribute(item, ViewableAttributeName);
}

private static bool IsOpaque(ICustomAttributeProvider item)
{
  return HasAttribute(item, OpaqueAttributeName);
}

private static bool HasAttribute(ICustomAttributeProvider item, 
  string attributeName)
{
  return item.CustomAttributes.Any(
    a => a.AttributeType.Name == attributeName);
}
