Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
In computer field, data format used in different software systems may be different, therefore in certain softwares
In the data exchange process of system, need to carry out the conversion of data format.Data processing method provided by the present application, mainly exists
It is converted between structural body object and JSON (JavaScript Object Notation, JS object numbered musical notation) message.Its
The middle process that structural body object is converted to JSON message becomes serializing, and JSON message is converted to the process of structural body object
Referred to as unserializing.
It should be noted that the application environment of the application be C++ programming language environment, performed program code be using
The code that C++ programming language is write.It is primarily due to, there is many system code of high performance demands all to use C++ programming language
Speech is write, and this language environment itself is not provided with " code reflection " function, therefore not can be carried out serializing and inverted sequence
The process of column.
Currently, in order to execute serializing and unserializing process, a kind of common processing under this language environment
Method be manually be that each structural body object writes serializing and unserializing function by programming personnel, in such software systems
How many structural body objects used, it is necessary to write serializing and the unserializing function of respective numbers.More specifically, serializing letter
It needs to write the code of splicing JSON message in number for each structural body object, needs in unserializing function for each structural body
Object writes the assignment code from JSON message to structural body object.
This kind of processing method is the prior art has at least the following problems: first is that each structural body object has respective serializing and inverted sequence
Columnization function, although the processing logic inside function is similar, since the specific structure difference of structural body object makes function not
It can be multiplexed, and then cause size of code larger；Second is that serializing function and unserializing function were executed in the code operation phase, fortune
The execution efficiency of row order section is lower, to reduce the whole efficiency of data processing.
Another kind carries out serializing and the method for unserializing does not need to write splicing for each structural body object
The code of JSON message, but the member variable for each structural body object is needed to write the generation with the mapping relations of JSON message
Code, then serializing unserializing function is executed, this mode can equally generate the problems in the first above-mentioned data processing method.
In order at least solve said one technical problem, this application provides a kind of data processing method, this method is used for
Complete serializing and unserializing step.
See Fig. 1, it illustrates a flow charts of data processing method.As shown in Figure 1, the data processing method is specifically wrapped
Include following steps S101~S104.
S101: the target type of structural body object is determined.
Wherein, a plurality of types of structural body objects can be pre-established in practical applications, and a structural body object is just made
For a kind of type structure object.Different structural body object orienteds is different, therefore the title table of structural body object can be used
Show the type of structural body object.
Structural body object include it is a variety of, need in specific implementation for which type of structural body object execute data processing
Method just determines the type of the structural body object, for ease of description, the type of the structural body object is known as target type.
Target type can be determining according to the program of calling notebook data processing method.Specifically, it calls at notebook data
The program of reason method can send to notebook data processing unit and instruct, and include the title of structural body object in instruction, and then will
The name of the structural body object received is referred to as the target type of structural body object.
S102: it is predefined macro in compilation phase execution, to obtain the member property letter of the structural body object of target type
Breath.
Wherein, macro is a kind of replacement of grammer, for illustrating how a certain specific input is converted into according to predefined rule
Corresponding output.Macro executed in the compilation phase, referred to as macro expansion.
The present invention is pre-defined, and to have macro, macro input parameter include the target type of structural body object, and macro function is to obtain
Take the information of the member property of structural body object.Member property information includes: the title of the character string forms of member property, member
The data type of attribute and the number of member property.
In order to make it easy to understand, being briefly described to the member property of structural body object.One structural body object can wrap
Containing several member properties, each member data has each customized data type.An entitled student described as follows
Structural body object shown in, the structural body object include two member properties, respectively name and age.The wherein data of name
Type is the character array comprising 10 elements；The data type of age is integer.
struct student{
char name[10]；
int age；
}
It is executed macro to obtain target type in the compilation phase to the target type of predefined macro input structure body object
The structural body object member property that is included above-mentioned attribute information.
In a kind of concrete implementation mode, it is predefined it is macro in include: macro, data type for stringification processing obtain
Take function and for the macro of the number that gets parms.For ease of description, it may be respectively referred to as the first macro, first function and second
It is macro.
Correspondingly, a kind of specific implementation of this step is as follows:
See Fig. 2, executes following step S201~S203 in the compilation phase.It should be noted that following steps are all in journey
What the sequence code compilation stage completed.
S201: it the name for the member property that the structural body object of target type includes is referred to as parameter is passed to be used for character string
Change the macro of processing, and executes for the macro of stringification processing, to obtain the title of the character string forms of member property.
Wherein, the name for each member property that the first macro incoming parameter includes by the structural body object of target type
Claim, it is character string that the first macro function, which is by incoming parameter processing,.To, by title be passed to first it is macro after, execute first it is macro just
The title of the character string forms of available each member property.
As shown in following examples:
#define PRINT_PARAMS (STRUCT_NAME, PROPERTY_NAME) // first parameter indicates structural body
The target type of object, second parameter indicate the title of member variable
{
cout<<#STRUCT_NAME<<""<<#PROPERTY_NAME；// it is previous it is macro be by this parameter of target type into
Line character string, it is latter it is macro be by this parameter of the title of member variable carry out stringification
}
It should be noted that input first it is macro be parametric form title, output be character string forms title, the
One it is macro only title handle as character string, such as the entitled name of the member property to the first macro interior input, export
Be title name labeled as character string.Why carrying out this processing is because carrying out serializing and antitone sequence subsequent
When change, need using the title after stringification.
S202: the title for the member property that the structural body object of target type includes is input to data type and obtains function
In, and execute data type and obtain function, to obtain the data type of member property.
Wherein, the present invention pre-defines first function, that is, data type and obtains function, and as its name suggests, the function of the function is
Its data type is determined for the parameter of input.The parameter of this step input includes the member property that structural body object is included
Title, therefore first function can be according to the title of member property, to determine the data type of member property.
The present invention applies in C++ programmed environment, and the function that C++ itself offer can be used realizes this function.Specifically
Ground, data type, which obtains function, can specifically include two functions, and one is constexpr function, and one is decltype letter
Number.
Wherein, the data type of each member property can have number-mark in advance.The function of constexpr function
It is that the number-mark of the data type of member property can be determined according to the title of the member property of input；Decltype function
Function be that the corresponding data type of the number-mark is determined according to the number-mark of data type.Therefore, in conjunction with two letters
Number can determine the data type of member property.
A kind of realization code is as follows:
#define REGISTER_TYPE(Type,Index)
REGISTER_TYPE (unsigned short, 1) // corresponding number-mark of data type unsigned short
It is 1
REGISTER_TYPE (unsigned int, 2) // corresponding number-mark of data type unsigned int is 2
REGISTER_TYPE (unsigned long long, 3) corresponding volume of data type unsigned long long
Number it is identified as 3
constexprstd::size_ttype_to_id(identity<Type>){return Index；}
template<class T>
struct identity{}；
For example, a specific calling process is as follows:
Std::size_tIdx=constexprstd::size_ttype_to_id (identity <unsigned int
>)；
// assume that the value of the Idx of constexpr function output is 2
decltype(Idx)type；//decltype function can determine that data type is according to number-mark 2
unsigned int
As it can be seen that the number-mark of the data type of member property is determined by constexpr function first, then by the volume
Number mark is input in decltype function and obtains the particular content of data type.
S203: it the name for all member variables that the structural body object of target type includes is referred to as parameter is passed to be used to obtain
The macro of number of parameters is taken, and is executed for the macro of the number that gets parms, to obtain the number of member property.
Specifically, pre-defined second is macro i.e. for the macro of the number that gets parms, which is all members
The title of attribute, the macro function are that the number of member property is determined according to the title of all member properties.
In C++ programmed environment, the macro method that the variable length generated can be obtained with reference to variadic macros.
A kind of realization code is as follows:
#define ARG_N (a1, a2, a3, N ...) // preset interception four figures N
#define ARG_N_HELPER(...)ARG_N(__VA_ARGS__)
#define COUNT_ARG(...)ARG_N_HELPER(__VA_ARGS__,3,2,1,0)
With COUNT_ARG (x, y) citing, the title of the member property inputted in the example is respectively x and y.Specifically hold
Row process is as follows:
COUNT_ARG(x,y)
->ARG_N_HELPER(X,Y,3,2,1,0)
-> ARG_N (X, Y, 3,2,1,0) // interception four figures is 2, to know that the number of the member property of input is 2
It is a.
To sum up, the present invention it is available to the information of member property include, the title of the stringification of member property, at
Member's data type of attribute and the number of member property.
S103: if desired the structural body object instance of target type is serialized in the execution stage, then according to member
Member property sequence in structural body object instance is turned to character string message example by attribute information.
Wherein, it needs to enter the execution stage after compiling, in the stage of execution, if receiving a certain tool to target type
The serializing of the structural body object of body is requested, then demonstrates the need for serializing a certain specific structural body object.Specifically
Structural body object be known as structural body object instance.
Specific serialization process includes that structural body object instance is passed into serializing function, serializing function according to
The target type of structural body object instance obtains the member property information that the compilation phase corresponds to target type, by structural body object
Member property sequence in example turns to character string message i.e. JSON message, wherein the character string message after conversion is known as character string
Message example.
The implementation procedure for serializing function is to determine member property all in structural body object instance, by member property
The names of character string forms be referred to as the key in character string message, and each member property is taken out from structural body object instance
Attribute value is assigned to corresponding key by attribute value.Key-value pair is assembled according to the reference format of JSON message, to obtain
Character string message example.
A kind of concrete implementation mode of this step is as follows:
If the request serialized to the structural body object instance of target type is received in the execution stage, by member
The number of attribute successively recycles each member property and executes following steps as cycle-index cut-off condition:
The name of the character string forms of member property is referred to as key, and acquisition title is corresponding from structural body object instance
Value, as the corresponding value of key；And the data type according to member property, the data type of the corresponding value of determination key；
Wherein, the key-value pair that each member property generates forms character string message example.
Specifically, it is asked if received in the execution stage to what the structural body object instance of target type was serialized
It asks, then circulate operation is carried out to the member property of structural body object instance, the content of each circulate operation is, in word to be generated
It accords with and adds a key-value pair in crossfire text example.
The specific adding procedure of key-value pair is that key is the title of the character string forms of member property, and value is from structural body pair
As the value of the member property extracted in example.In addition, each value in key-value pair is it needs to be determined that data type, different data
The data format of type, value is different.The data type of value from member property data type, therefore by member property
Data type as value data type.
It should be noted that cyclic process is controlled by cycle-index, 1 initially is set by cycle-index, every circulation primary,
By cycle-index plus 1, until the value of cycle-index is equal to the number of member property, circulation terminates, to generate character string
Message example.
S104: real in if desired structural body object that character string message example is deserialized as target type by the execution stage
Character string message example, then according to member property information, is deserialized as the structural body object instance of target type by example.
Wherein, it needs to enter the execution stage after compiling, in the stage of execution, if received a certain specific character string
Message is deserialized as the request of the specific structural body object of target type one, then needs to be implemented unserializing process, antitone sequence
Change process is to generate a specific structural body object.Wherein, specific character string message is known as character string message example, tool
The structural body object of body is known as structural body object instance.
Specific unserializing process includes inputting character string message example into unserializing function and will being assigned
Structural body object instance, for unserializing function according to the target type of structural body object instance, obtaining the compilation phase corresponds to mesh
Character string message instance transfer is structural body object instance according to member property information by the member property information for marking type.
The implementation procedure of unserializing function is, according to segment identifiers such as " { } []: " etc. from character string message example
Each key-value pair is extracted, each key is matched with the member property in the structural body object of target type, by each key
Value is as the value with the matched member property of key.
More specifically, a kind of specific implementation of this step is as follows.
If receiving the structural body object instance that character string message example is deserialized as to target type in the execution stage
Request successively each member property circulation is executed following then using the number of member property as cycle-index cut-off condition
Step:
The name of the character string forms of member property is referred to as to the target designation of the member property of structural body object, and from word
It accords with and extracts the corresponding value of title, the target value of the member property as structural body object instance in crossfire text example.
It should be noted that cyclic process is controlled by cycle-index, 1 initially is set by cycle-index, every circulation primary,
By cycle-index plus 1, until the value of cycle-index is equal to the number of member property, circulation terminates, to be structural body pair
As each member property of example is assigned to target value.
From the above technical scheme, this application provides a kind of data processing method, this method determines structural body first
The type of object, it is predefined macro in compilation phase execution, to obtain the information of the member property of the structural body object of the type,
Serializing or antitone sequence process are carried out in the execution stage according to the information of the member property.Compared with prior art, in this method
Programming personnel is not necessarily to splice message for different structural body object manual compiling, macro can obtain each knot using predefined
The information of the member property of structure body object, so as to greatly reduce size of code, and macro expansion be in the compilation phase rather than
The execution stage, when executing stage needs serializing or unserializing, without repeating this process, so as to improve data processing
