what is object serialization

Most of the time, we understand that object-oriented means adding methods to data, encapsulation means hiding data, but this is not comprehensive. For example, a cat has a head, four legs, and a tail. Although there is no error, it is not comprehensive. In terms of appearance, this

JS provides 11 types of references: Object, Array, Date, Function, Error, REGEXP, Math, number, String, Boolean, globle. This includes three basic wrapper types, number, String, and Boolean, which are special reference types that are similar to other reference types and have special behaviors corresponding to their original types.First, what is the type of packag

Array in C #, what is the difference between ArrayList and List object, In C #, when we want to store a group of objects, we will think of using arrays, ArrayList, and List. So what are the differences between the three?Let's take a look at the array first, because the array first appeared in C.Array Arrays have many a

Object serialization in. net Piet ObermeyerMicrosoft Corporation August 2001 Abstract:Why use serialization? The two most important reasons are: Saving the object state in the storage media so that identical copies can be re-created later; send objects from one application domain to another by value. For example,

What is coverageIn Java, overrides are the concept of inheritance, where a subclass needs some method or property, but does not want to use a method or property of the same name in the parent class.To be blunt, it is to write a method with the same name, the same number of parameters, the same return value, or a pr

Before all the text, I need to emphasize that I personally opposed to structure typing, so even if the content of the text "looks like" go interface, readers should not feel that I am praising go interface. What I like more is the way that Haskell and rust. Unfortunately rust and go as much as I want to shrink all the words are the shortest, the result code written to even the readability

In fact, I don't want to comment on this question any more, but I have a lot to answer, so I have to post a reply.

main task of application analysis is to dynamically describe the legal state sequence of the object in the system, to express the dynamic behavior of the object with the dynamic model, the message transmission between the objects and the dynamic information of the cooperative work, the basic idea of theOTM method is t

What is object-oriented. This question puzzled me for a long time, In reading a book that has a After writing thousands of lines of code, I've learned so many times, Many times I think I've found the answer, Just like I'm asking the answer to love, The answer to happiness is the same, Every time the answer, To

Serialization is the process of converting the object state to a format that can be maintained or transmitted. In contrast to serialization, deserialization converts a stream into an object. These two processes can be combined to easily store and transmit data. For example,

IntroductionSerialization refers to the process of storing the status of the object instance to the storage media. In this process, the public and private fields of the object and the name of the class (includingProgramSet), and then write the byte stream into the data stream. When the object is deserialized, a copy id

The title of the next section was supposed to be "an overview of the classes in the hotel management system", which now appears to be "an overview of the objects in the hotel management system". It may seem irrelevant, but now that Allen Holub it clearly, I think he has his own meaning (and rightly so) that the methods used in Delphi programmin
