In the science of programming, marshaling or marshaling (American notation) can be the process of converting an object’s memory expression into data, formatting it suitable for storage or transmission.[edit] Typically used when data needs to be moved around very differently between parts of a desktop program or from one program to another.
Marshaling can be something like or related to serialization. Marshalling describes the transfer of a target or process to an object via a client to a server, the goal is to deliver the same object that is in a running program to another running program i.e. be an object in the client to be prepared and passed to the server. . Serialization does not necessarily pursue this goal, since it is, for example, about passingBreaking down data into a large stream of bytes. It’s easy to say that marshaling is somewhat different from serialization, but two forms of serialization are commonly used.[1]
This simplifies complex communication by using compound topics instead to link old objects. The reverse process of marshaling is unmistakably called unmarshaling (or unmarshaling, analogous to successful deserialization). The disorganization interface takes the serialized protest and turns it into an internal evidence structure that can be referenced in the executable.
The precise definition of marshaling varies across programming languages such as Python, Java, and .NET in some contexts and is interchangeable with serialization.
Comparison With Serialization
To you, “serializing” a good object means converting its state directly into a byte stream, so that the byte stream can be converted back into a copy of the person object.
The term “marshal” is used for a special type of “serialization” in the Python Essential Library[2], Python’s internal object store:
What do you mean by marshalling?
The Marshal part is primarily intended to support reading in conjunction with writing “pseudo-compiled” code for Python quests from .pyc files.

In Java-related RFC 2713, marshaling is used when objects are serialized on behalf of remote calls. The object, which is usually marshaled, retains the state of the original article, and contains a code base (the code base below refers to the list of URLs where the code for the object can be downloaded, not the source code). Therefore, an order must be made to convert the state of the object, and hence the codebase(s), to unmarshall. The non-marshalled user interface automatically converts the ordered data, which consists of a code base, into a Java executable in a JAXB object. Any object that can be deserialized can, in many cases, be disorganized. However, the reverse may not be true.
What is request marshalling?
Marshalling is the process of converting a higher level structure (object) directly into some lower level representation, often a true “framework”. For example, marshaling is used on the server side to convert this application domain object into a response object.
“Marshaled”object” means to store its state and codebase(s) in such a way that when “unmarshaling” a marshaled object, a copy of the innovative object is retained, possibly automatically. class definitions. You can marshal any object that is normally serializable or remote (i.e. e. implements a specific java.rmi.Remote interface.For example, marshaling is similar to serialization, except that marshaling also preserves codebases.Shunting may differ from serialization in that dog bones specifically manage remote objects.
…
Any object whose methods are frequently called [on another JVM object] must implement the java.rmi.Remote interface. When such an object is considered invoked, its arguments are collected and passed from the local virtual machine to the remote machine, where the arguments can be unpacked and used.

Microsoft .NET also uses marshaling to introduce serialization when using remoteNew:
When you marshal an object by value, a copy of the object is created and serialized so that the server can do it. All method calls made through this object will be executed on your current server

What does it mean to marshal data?
In the modern user interfaceKe marshaling or marshaling (US spelling) is the process of converting a representation of an object’s storage law into a data style suitable for storage or transmission. It is also commonly used when data needs to be processed between different parts of a computer science course or program.
Marshaling is used in implementations related to various remote procedure call (RPC) mechanisms where data needs to be passed between processes and/or between threads. In the Microsoft Component Object Model (COM), interface pointers must be marshaled when they cross COM apartment boundaries.[6][7] Convert between an unmanaged complex type and a CLR type, like the P/Invoke process, is also an incredible example of an action that requires marshaling.
Dialect calls to Go orchestrated the process of generating a specific JSON string from a data structure, and also disorganized the process of parsing JSON for a data structure.
What is meant by marshalling an int?
Marshaling is a process somewhere between managed code and unmanaged code; This is one of the main services offered by the CLR. See activity in this post. Ideally marshaling an int is exactly what you said: copying the memory that spans the managed CLR stack to a place where C code can see it.
