CN103176803A - Code serialization method - Google Patents

Abstract

The invention discloses a code serialization method and belongs to the field of software development. The computer software consists of codes and data, and the functions of the software are shown by the codes and data. The code serialization method comprises the following steps: 1, assigning the codes to a character string code so as to realize code serialization, compiling the serialized codes into machine codes which can be identified by a virtual machine, thus obtaining a character string P-Code; and 2, combining the character string P-Code and host software. The code comprises an applied logic, the data can be stored and transmitted in the software operation, and the codes are relatively stable in the operation process and cannot be changed. The increase and change of the functions of the software can be generally realized by data only. After the codes are serialized into data, the data can be transmitted and changed and is reduced into codes, and the flexibility of the software is improved; and moreover, the method is suitable for business software development.

Description

A kind of method of code sequence

Technical field

The present invention relates to technical field of computer programs, a kind of method of code sequence is provided.

Background technology

the increasing micro-chip processor of using in present various product, go to control the behavior of product with software, improving reliability and the expanded function of product. the characteristics of this series products are, software embodies in the mode of firmware, in case install, not by producer and and the specialized maintenance station just basically can not upgrade to software. in order to solve the problem of having found, such as automobile industry, solve by recalling a large amount of same model products. waste time and energy. also allow potential problem solve and can not get timely processing. such as the brake problem of some automobile, be exactly the problem of software control algorithm or logic. repair software, will inevitably cause solidification software again. other desktop software system also exists similar problem, such as the software of a production control flow process, change due to user's flow process, causing the variation of software. the variation of any software is upgraded, all need again to issue, if be from developing software, not affecting present production if need to upgrade each computer software. difficulty and cost are all larger. and be the business software of buying, be difficult in time obtain upgrading so later software. those problems above-mentioned, all in software life-cycle in fact, variation due to software requirement, cause the variation of code, thereby cause issue again and the installation of software.

Here introduce our ratio juris with a simple example. take the charging unit of automobile as example, the below is a software model of having simplified fully:

Charging unit object (Charger)

{

Attribute:

Current battery tension (V)

Voltage minimum (Min)

Voltage max (Max)

Detect voltage time interval (Interval)

Method:

Detect current voltage (Detect)

Charging (Charge)

{

If current voltage＜voltage minimum is charging just

If current voltage〉voltage max just stop the charging

}

}

above-mentioned object is exactly data (Data) and code (composition), data embody with attribute, such as current voltage, code is exactly that method with applied logic embodies, such as charging method. code section can not change after the software issue and before the issue of next version, data are to store, change, be delivered to the other system of automobile. cause software change except revising existing system, also have other factors also to cause the upgrading of software to change, for example: system need to increase new function, revise and strengthen existing function, delete unwanted function, above-mentioned behavior also can cause the variation of data structure, take relational database as example, cause increasing and decreasing the row of tables of data, type and the width change of row.

Summary of the invention

The present invention be intended to provide a kind of by serializing with code data, and the later code of datumization in essence or data, so long as data are just revised very easily, update routine is by revising getting final product of the later data stream of serializing, facilitates like this method of code sequence of the modification of later stage program.

The present invention is to achieve these goals by the following technical solutions:

A kind of method of code sequence is characterized in that comprising the following steps:

Step 1, with the code value of paying to a character string code, code serializing; The later code of serializing, be compiled into the machine code of virtual function identification, obtain character string P-Code;

Step 2, character string P-Code and host software are combined.

In such scheme, described character string code is stored in lane database, then reads from lane database, with the position of character string forms link (insertion) to original serializing.

In such scheme, adopt script.Execute (code, this) to carry out the unserializing action, the data character string code that serializing is later and current host software runtime environment this pass to script.Execute (code, this), the code after executing data.

In such scheme, host software combines and can adopt following 2 kinds of methods:

The first: P-Code, be converted to the machine code of host software, such as Java language, so just be converted to bytecode;

The second: be dynamically embedded into operation.

Code sequenceization is common a kind of sequencing method to the character crossfire, can also serializing arrive binary data, XML etc., for the ease of the simplification problem, with describe the problem, the later data layout of seriation is directly with the form of code source program, this is exactly the character string code that in literary composition, example is showed, because use source program format, using serializing is exactly a simple job, there is no in article and carry. key problem in technology is exactly how the later character crossfire unserializing of serializing, allows it equally go operation with real code.

1, a definition character string code (this is exactly the later data of serializing in fact), this character string is to be stored in lane database usually, then reads from lane database, with the position of character string forms link (insertion) to original serializing;

2, adopt script.Execute (code, this) carry out the unserializing action, code (data that serializing is later) and this (current host software runtime environment) are passed to script.Execute (code, this), the code after executing data.

The advantage that adopts above technical scheme is exactly with code data by serializing, and the later code of datumization in essence or data, so long as data are just revised very easily, update routine facilitates the modification of later stage program like this by revising getting final product of the later data stream of serializing.

The present invention has following beneficial effect:

This method allows the code that has existed that the straightforward procedure of a serializing has been arranged, thereby improves the flexibility of software.By the modification to the later data of code sequenceization, increase and newly subtract function, thereby allow the consumer of data after code sequence, in the situation that do not reinstall/solidification software, update functions has been arranged. can be a large amount of economize on the use of funds and the time. wide market outlook are arranged.

Embodiment

A computer system has even up to a hundred microprocessors (perhaps computing machine) composition of dozens of usually, and these collaborative computers participate in finishing the work.What transmit between computing machine is all data (message, order, data) basically.After computing machine is received data, carry out corresponding predetermined action, but can't produce a new action (action outside predetermined action).System cooperating is completed a task according to certain flow process (workflow).Flow process is preset.In computer realm, exactly object (object) serializing (Serialization) is delivered to other computing machine and is reduced to object (Deserialization), carry out predetermined action (operation).The later data that obtain of serializing can also be stored except transmitting.The serializing of object is exactly the serializing to the software object attribute in essence.The form of common serializing data has 2 classes, and a class is privately owned binary format data, and also having a class is to use the XML form, or the mutation of XML, and widely used have JSON, such as the SOAP form that uses in Web Service.Take the charging object as example, the below is the data layout of XML:

<Charger>

<Voltage>10</Voltage>

<Max>14</Max>

<Min>7</Min>

<Interval>5</Interval>

</Charger>

The JSON form:

{"Charger":

{"Voltage": 10,

"Max": 14,

"Min": 7

"Interval": 5

}

}

So-called action is exactly to carry out some computer codes, the method in computer software namely, and generally we can not be to code sequence.Code is used for presentation logic knowledge.If code also can serializing, represent that so software has:

1, the transmission capacity of knowledge: if we can be delivered to some code sequences in other computing machine B from computer A, allow computing machine B carry out corresponding new action.

2, the self-learning capability of knowledge: in the situation that computing machine loses and other computing machine contacts, oneself has learning ability computing machine.Carry out and create the action that makes new advances.

Traditional way is used knowledge system, and in essence or data transmission and generation, these knowledge can produce new action, but these actions or preset, and it can not solve the problem of generation new element.

1, do intelligence system, such as knowledge represents (essence or traditional data) with rule

2, knowledge can also represent with model, such as the model of neural network (being a data structure)

The example of the code sequence of the above's charging object is:

{"Charger":

{"Voltage": 10,

"Max": 14,

"Min": 7

"Interval": 5

"Charge": if(voltage > Max) StopCharge(); if(Voltage<Min) StartCharge();

}

}

After code sequence turned to data, except the attribute as the knowledge representation of code own, as data attribute, the later code of serializing can be retrieved by image data like that, revised increase and decrease.How the serializing code has become key issue.

If designing and developing of brand-new software can be selected above-mentioned design so. for the software that has existed, the top design effort of taking a lot of work that seems.

The below is process and the grade of the example serializing that comes description code with C# language design Windows Form window.This simple Form shows a Label and a Button exactly.

After clicking Button, the displaying contents of Button is " OK ", the content of Label is shown as " and Good bye (n) "

After clicking Label, the displaying contents of Button is " Cancel (n) ", the content of Label is shown as " and Hello World ", wherein (n) clicks for the n time for integer representation. and following is the C# program of standard, can programing operation

1 class LabelButtonForm0 : Form

2 {

3 private System.Windows.Forms.Button button1;

4 private System.Windows.Forms.Label label1;

5 int count = 0;

6 public LabelButtonForm0()

7 {

8 button1 = new System.Windows.Forms.Button();

9 label1 = new System.Windows.Forms.Label();

10 button1.Location = new System.Drawing.Point(50, 140);

11 button1.Size = new System.Drawing.Size(120, 24);

12 button1.Text = "Cancel";

13 label1.Location = new System.Drawing.Point(50, 40);

14 label1.AutoSize = true;

15 label1.Size = new System.Drawing.Size(120, 24);

16 label1.Text = "Good Morning!";

17 Controls.Add(this.label1);

18 Controls.Add(this.button1);

19 button1.Click += delegate(object sender, EventArgs e)

20 {

21 ((Button)sender).Text="OK";

22 label1.Text = "Good bye "+ count++;

23 };

24 label1.Click += delegate(object sender, EventArgs e)

25 {

26 ((Label)sender).Text="Hello World";

27 button1.Text = "Cancel " + count++;

28 };

29 this.Show();

30 }

31 }

We demonstrate the Event triggered serializing Button and Label now, and button1.Click and label1.Click sequence turn to the information flow of string format, and the below is example:

1 class LabelButtonForm1 : Form

2 {

3 private System.Windows.Forms.Button button1;

4 private System.Windows.Forms.Label label1;

5 int count = 0;

6 Script script = new Script();

7 public LabelButtonForm1()

8 {

9 button1 = new System.Windows.Forms.Button();

10 label1 = new System.Windows.Forms.Label();

11 button1.Location = new System.Drawing.Point(50, 140);

12 button1.Size = new System.Drawing.Size(120, 24);

13 button1.Text = "Cancel";

14 label1.Location = new System.Drawing.Point(50, 40);

15 label1.AutoSize = true;

16 label1.Size = new System.Drawing.Size(120, 24);

17 label1.Text = "Good Morning!";

18 Controls.Add(this.label1);

Controls.Add(this.button1);

19 this.Text = "Event Handler";

20 string code=" code that // serializing is later

21 button1.Click += delegate(sender,e)

22 {

23 sender.Text='OK';

24 label1.Text = 'Good bye '+ count++;

25 };

26 label1.Click += delegate(sender,e)

27 {

28 sender.Text='Hello World';

29 button1.Text = 'Cancel ' + count++;

30 };

31 ";

32 script.Execute(code, this);

33 this.Show();

34 }

35 }

More top two programs, we can find, the later code section (20-32 section) of serializing is consistent with original code basically.Unique difference is used dynamic variable exactly. do not need to state types of variables.Serializing module (Script) can the Auto-Sensing type of variables.

We also can carry out serializing to the attribute statement of Button and Label. referring to the 15-21 section of code.

1 class LabelButtonForm2 : Form

2 {

3 private System.Windows.Forms.Button button1;

4 private System.Windows.Forms.Label label1;

5 int count = 0;

6 Script script;

7 public LabelButtonForm2()

8 {

9 button1 = new System.Windows.Forms.Button();

10 label1 = new System.Windows.Forms.Label();

11 Controls.Add(this.label1);

12 Controls.Add(this.button1);

13 script = new Script();

14 string code=" code that // serializing is later

15 button1.Location = new System.Drawing.Point(50, 140);

16 button1.Size = new System.Drawing.Size(120, 24);

17 button1.Text = 'Cancel';

18 label1.Location = new System.Drawing.Point(50, 40);

19 label1.AutoSize = true;

20 label1.Size = new System.Drawing.Size(120, 24);

21 label1.Text = 'Good Morning!';

22 button1.Click += delegate(sender,e)

23 {

24 sender.Text='OK';

25 label1.Text = 'Good bye '+ count++;

26 };

27 label1.Click += delegate(sender,e)

28 {

29 sender.Text='Hello World';

30 button1.Text = 'Cancel ' + count++;

31 };

32 ";

33 script.Execute(code, this);

34 this.Show();

35 }

36 }
