What is marshalling used for?

In computer science, marshalling or marshaling (US spelling) is the process of transforming the memory representation of an object into a data format suitable for storage or transmission. It is typically used when data must be moved between different parts of a computer program or from one program to another.

Why is it called marshalling?

Usually the word "marshalling" is used when you're crossing some sort of boundary. Three obvious use cases: Remoting: the RPC data is marshalled to a separate machine (usually) AppDomains: an object crossing an AppDomain boundary needs to be marshalled (or it may be marshalled by reference)

Marshaling and serialization are loosely synonymous in the context of remote procedure call, but semantically different as a matter of intent. In particular, marshaling is about getting parameters from here to there, while serialization is about copying structured data to or from a primitive form such as a byte stream.

What is marshalling and its types?

Marshalling is the process of transforming types when they need to cross between managed and native code. Marshalling is needed because the types in the managed and unmanaged code are different.

What does marshalling data mean?

To prepare data for processing or for transport over a network. Data marshalling may collect data from a single source or from multiple sources, but then performs the necessary conversion to a common format for processing or for transmission.

Is it marshaling or marshalling?

Marshal (one l) is correct in English. However, both Marshalling or Marshaling are correct. Marshalling (with two lls) "seems to make more sense" in my American-English mind as it softens the "a" explicitly.

Copies data from a managed array to an unmanaged memory pointer, or from an unmanaged memory pointer to a managed array.

Why is it called serialization?

Data stored on a tape is obviously stored in a serial way, i.e. it's basically a series of bits from one end of the tape to the other. However, it's not only data on tapes that is serial in this way.

What is serializing an object?

Serialization is the process of converting an object into a stream of bytes to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization.

What is serialization in OOP?

Introduction. Serialization or marshaling is the process of converting object state into a format that can be transmitted or stored. The serialization changes the object state into series of bits. The object state could be reconstructed later in the opposite process, called deserialization or unmarshalling .

What is lazy loading C#?

Object on Demand is also called Lazy loading pattern, Lazy loading delays the initialization of object. This is a new feature of C# 4.0 and can be used when we are working with large objects when it is not in use.

Can a class be static in C#?

In C#, one is allowed to create a static class, by using static keyword. A static class can only contain static data members, static methods, and a static constructor.It is not allowed to create objects of the static class. Static classes are sealed, means you cannot inherit a static class from another class.

What is polymorphism in C#?

Polymorphism, in C#, is the ability of objects of different types to provide a unique interface for different implementations of methods. It is usually used in the context of late binding, where the behavior of an object to respond to a call to its method members is determined based on object type at run time.

What is marshalling and Unmarshalling in operating system?

Marshalling is the process of transforming the memory representation of an object to a data format suitable for the storage and transmission. Unmarshalling refers to the process of transforming a representation of an object that is used for storage or transmission to a representation of the object that is executable.

What is marshalling and unmarshalling JSON?

JSON has 3 basic types: booleans, numbers, strings, combined using arrays and objects to build complex structures. Go's terminology calls marshal the process of generating a JSON string from a data structure, and unmarshal the act of parsing JSON to a data structure.
