Why do managed attributes just work for class attributes and not for instance attributes in python?

help you fix your problem To answer your second question, where is _v? Your version of the descriptor keeps _v in the descriptor itself. Each instance of the descriptor (the class-level instance SomeClass1, and all of the object-level instances in objects of class SomeClass2 will have distinct values of _v. class MyDescriptor(object):
def __get__(self, obj, type=None):
print "get", self, obj, type
return obj._v
def __set__(self, obj, value):
obj._v = value
print "set", self, obj, value

Is it possible to serialize property attributes to XML attributes in C#?

I think the issue was by ths following , I think you're going to have to write your own XML serialization for this and mix in some reflection to check attribute values on properties. There's a good guide to implementing the IXMLSerializable interface here. Unfortunately you will have to implement serialization of all properties in the class, but on the bright side, if you implement IXmlSerializable correctly, you can still use the XmlSerializer class. public class YourClass : IXmlSerializable
{
[IsDirty(true)]
public string Name { get; set; }
// skipped ReadXml and GetSchema interface methods for brevity
public void WriteXml(XmlWriter writer)
{
writer.WriteStartElement("YourClass");
var myType = typeof(YourClass);
foreach(var propInfo in myType.GetProperties())
{
writer.WriteStartElement(propInfo.Name);
foreach(var attr in propInfo.GetCustomAttributes(typeof(IsDirtyAttribute), false))
{
var myAttr = attr as IsDirtyAttribute;
writer.WriteAttributeString("Dirty", attr.Value ? "true" : "false");
}
writer.WriteEndElement();
}
writer.WriteEndElement();
}
}

What is the proper way to check for nulls when accessing attributes of attributes of attributes?
Date : March 29 2020, 07:55 AM
Any of those help This style is to be avoided as far as possible - see the Law of Demeter - though I appreciate that library or legacy code may not leave you much option. Functional programming languages (in particular) avoid this problem through the use of Option or Maybe objects, which can be used in Java to some extent. See this article, for example. Long sequences of null checks can be avoided concisely using Scala for-comprehensions, for eaxmple. But back to Java...

hop of those help? EDIT: After you have revealed the actual problem, I have also changed the stylesheet. Again, your input is not well-formed XML because a namespace is not defined: `xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Xcode access attributes inside user defined runtime attributes
Date : March 29 2020, 07:55 AM
hop of those help? I don't believe that's possible. A runtime attributes value must be a constant, not a variable / property.
