Questions tagged [marshalling]

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).
