Marshalling is the process of transforming the memory representation of an object to a data format suitable for storage or transmission

Marshalling is the process of packing parameters to a message. The reverse process is called unmarshalling. The accurate definition of marshalling differs across programming languages such as Python, Java, and .NET, and in some contexts, is used interchangeably with serialization. The term is also used in RPC steps. For example marshalling in Java is the process of converting Java objects into XML format (JAXB).

JAXB creating context and marshallers cost

The question is a bit theoretical, what is the cost of creating JAXB context, marshaller and unmarshaller? I've found that my code could benefit from keeping the same JAXB context and possibly the same marshaller for all marshaling operations rather…

Marshaling – what is it and why do we need it?

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 can't C# just send the 32 bits over with a starting and terminating signal, telling C code that it…

What input will cause golang's json.Marshal to return an error?

From the docs: JSON cannot represent cyclic data structures and Marshal does not handle them. Passing cyclic structures to Marshal will result in an infinite recursion. I've experienced this situation, which results in a runtime panic. What I'm…

What is marshalling? What is happening when something is "marshalled?"

I know this question has been asked, at least here. But there wasn't a satisfactory answer, at least not to me. There is a lot of talk about marshalling as regards interoperating with unmanaged code, but what about marshalling from one thread to…
