I am not sure what you mean about the last part, could you please elaborate .
You're using a List<Object> and Object is a reference type, so your list will hold references to instances .

I don't want to use XML file created by JAXB marshaller, can I customize it, so that i would give a preferrable format to marshal objects?

If you need to customize the xml then you can use the Jaxb annotations http://java.sun.com/javaee/5/docs/api/javax/xml/bind/annotation/package-summary.html

In any case its undefined behavior, it will crash....
It will probably try to read from NULL, or something .
NULL is obviously not a pointer to a null terminated array .
Well what do you think ? LPstr is A pointer to a null-terminated array of ANSI characters .

I know that in terms of several distributed techniques like RPC the term Marshalling is used, but I don't get the difference with Serialization. It both is transforming objects to series of bits no?

In other words, you would not be able to marshal and unmarshal an object into a state-equivalent instance.

From this question and my own benchmarks it seems that the marshal module is about 20-30x faster than cPickle. Why is this so? What functionality does cPickle offer over marshal that justifies this? (Another way of putting it - why not always use marshal...

Probably that's why marshal is faster.
So, it appears to me that (a) marshal is binary in nature, and (b) pickle is character in nature.
Objects through RPC calls, see the modules pickle and shelve .

What is marshalling and why do we need it.
I find it hard to believe that i cannot send an int over the wire from c# to c and have to marshall it. Why cant c# just send the 32bits over with a starting and terminating signal, telling C code that it has...

You can try to use the XmlJavaTypeAdapter annotation and your implementation of XmlAdapter interface .

Hi,
I have an unmanaged struct I'd like to marshal to c sharp that looks basically like this:
struct MyStruct{ /* ... some stuff ... */ int numChilds; MyStruct *childs; }
I believe that I have to write a custom marshaller but I'm not sure on how to proceed...

If you want just to pass it to some unmanaged function, you could just use unsafe code and stackalloc / fix an array to get a pointer to the array of objects .

Can XmlJavaTypeAdapter marshal from ClassA object to ClassB object? So that when :
public void createClassB (ClassB b) { }
I can pass in ClassA object. Does it possible?
Answer Snippets (Read the full thread at stackoverflow):
A little different solution, which is odd.
So, quiet similar to the example, you should be able to marshal ClassA object to ClassB or something.
marshal a Currency object as a String into your XML.
