Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings.
The method for generating a model of an object provided in the embodiments may be performed by a model generating device of an object, where the model generating device of an object may be implemented in a software and/or hardware manner, and the model generating device of an object may be formed by two or more physical entities or may be formed by one physical entity. The model generation device of the object can be a computer, a mobile phone, a tablet or an intelligent interactive tablet and the like. In the embodiment, the model generating apparatus with a computer as an object is described as an example, wherein the computer may be a desktop computer or a notebook computer, which has a code input function and is provided with a grammar library of a plurality of programming languages, and in general, the computer can meet general programming requirements.
Specifically, the method for generating the object model provided by the embodiment is suitable for a scene in which the same object is modeled in different programming languages. For example, in a Windows system, a local electronic whiteboard application is developed by using a C # language, and a web-based electronic whiteboard application is developed by using a JavaScript language. At this time, objects in the local electronic whiteboard application exist model objects in the C # language, and all of "handwriting", "rectangle", "circle", and "picture" have model objects in the C # language. The object in the webpage version electronic whiteboard application also has a model object in the JavaScript language. In order to ensure compatibility between the local electronic whiteboard application and the web page version electronic whiteboard application, for example, the same "rectangle" may be used in both the local electronic whiteboard application and the web page version electronic whiteboard, it is necessary to ensure that the model object of the same object in the C # language is completely consistent with the model object in the JavaScript language. The method for generating the model of the object provided in the embodiment is just applied to the above example scenario to provide a simple and fast method for realizing modeling of the same object in different programming languages.
Example one
Fig. 1 is a flowchart of a method for generating a model of an object according to an embodiment of the present invention. Referring to fig. 1, the object code generation method provided in this embodiment specifically includes:
and S110, acquiring a model definition file.
The model definition file is used for defining an object to be modeled.
Specifically, an object refers to a single individual that actually exists in the real world. The object to be modeled refers to an object which needs to be modeled currently. The model object is a section of program which ensures that the object to be modeled can be called by an application program in the using process of the application program. For example, if the object to be modeled is a rectangle, then the model object may be a piece of program that enables an electronic whiteboard application to draw the rectangle. Generally, the programming language of the model object is the same as the programming language used by the application program when running, for example, the application program is an application in C # language, and then the programming language of the model object is C #.
For example, when generating the model definition file, the programming language of the model object does not need to be considered, and the model object is described by using the set intermediate syntax. Specifically, the specific content of the intermediate grammar can be set according to the actual situation. Optionally, in the embodiment, the model definition file includes: the documentation of the field, the name the field was used to store, and the field definition. Wherein the field represents the object to be modeled or the model base data of the object to be modeled. The model basic data of the object to be modeled comprises elements of the object to be modeled or parameters called by the model object. An element is a child object that the object to be modeled includes at the time of invocation. For example, the object to be modeled is a page, the corresponding element may be a rectangular box displayed in the page, and the called parameter may be height, width, background color, and the like. Further, the name used when the field is stored may be understood as the name used when the field is stored by the computer, which is generally the name of the field type, for example, the name may be: page, height, width, background color, etc., without reference to the type specific data. In the subsequent process, the computer can call corresponding programs in other files according to the name. In general, the same field stores the same name in different files, e.g., the name in the model definition file is the same as the name that the field stores in the object model base data. The basic data of the object model is generated by the pointer to the object to be modeled and contains the code data of the attribute information of the object to be modeled.
Based on the specific contents of the model definition file, exemplary description of the corresponding intermediate syntax is as follows:
the syntax includes a model name (modelname), a document description of a field, a name used when the field is stored, and a field definition. Based on the model definition file, the computer may determine the object to be modeled. In general, a model definition file only implements the definition of objects to be modeled, and does not refer to the specific programming language of the corresponding model object.
And S120, generating a language model of the programming language based on the model definition file.
Wherein, the language models corresponding to different programming languages are different.
In particular, the programming language is a formal language used to define computer programs. The programming language mentioned in the embodiments may be selected as a high-level programming language, which may include at least one of: c language, C + + language, C # language, Java language, JavaScript language (JS language), Typescript language, Microsoft Visual C + + language. In practice, the programming language may also include other categories, such as structured query language, etc. Generally, as long as the conversion relation and the language library of the programming language are stored in the computer, the language model of the programming language can be generated based on the model definition file. Optionally, the programming language of the currently generated language model may be determined according to a programming language environment when the application program is running, for example, a certain application program only includes a Java language environment and a C + + language environment, and at this time, only the Java language model and the C + + language model need to be generated.
Specifically, the language model of the programming language is generally source code in the programming language, which represents basic rules of the object to be modeled when generating the model object in the programming language. The same object to be programmed can correspond to different language models in different programming languages, and different objects to be programmed can correspond to different language models in the same programming language. In generating the language model of the programming language, the template recognition model definition file may be generated using a code of the programming language. The code generation template is a basic rule of the code writing under the programming language, is irrelevant to an object to be coded, and can be understood as a universal rule. Generally, a code generation template of a programming language only needs to be generated once, and can be used for identifying a model definition file of any object to be coded to generate a language model of the object to be modeled in the programming language.
And S130, acquiring the basic data of the object model of the object to be modeled.
Illustratively, the object model basic data refers to code data which is generated aiming at an object to be modeled and contains attribute information of the object to be modeled. In short, the basic data of the object model may include an application program or all data that may be used by the application program when the application program uses the object to be modeled in a certain scenario, where the application program does not limit the version mode, such as the application programs of a mobile phone end, a computer end, and a web page end. In practical application, the contents of the object model basic data corresponding to different objects to be modeled may be different, and the specific contents included therein may be set according to actual conditions. Taking an object to be modeled displayed in a display screen as an example, the basic data of the object model comprises: the method comprises the following steps of identifying Identification (ID) of an object to be modeled, height of the object to be modeled, width of the object to be modeled, background information of the object to be modeled, element data contained in the object to be modeled and the like. Wherein, the background information of the object to be modeled comprises a background color. Further, the element data included in the object to be modeled includes basic information of the element, and the basic information specifically includes: the geometry of the element, the background color of the element, the foreground color of the element, the thickness of the element, the line type of the element, the opacity of the element, the ID of the element, the coordinate position of the origin of the element, the width of the element, the height of the element, the angle of the element, whether the element is locked, whether the element is copied, the position of the center of rotation, and the like. Generally, the basic data of the object model is input by a developer and then stored in a computer so as to be called and used by the computer when needed, and the basic data can be generally regarded as a document and not a method.
Further, the Object model basic data is Extensible Markup Language (XML) data or JavaScript Object Notation (JSON) data.
In the embodiment, an XML or JSON is adopted to describe the object to be modeled so as to obtain basic data of the object model. XML is a markup language for marking electronic documents to have a structure. XML can structure documents and data to facilitate the description of objects. JSON is a lightweight data exchange format that stores and represents data in a text format that is completely independent of the programming language. XML and JSON can simply and clearly describe the object to be modeled in a structured way, so that the model object can be conveniently generated according to the basic data of the object model. It should be noted that XML and JSON are only two preferred formats of the object model basic data, and in practical applications, other data formats that can be used for describing the object to be modeled can be used for the object model basic data.
And S140, inputting the basic data of the object model into a language model of the programming language to obtain a model object of the object to be modeled in the programming language.
The model object is generated by converting the basic data of the object model by the language model of the programming language, the model object is used in the application program, and the application program is a program in the programming language environment. For example, the model object is a rectangle used in the electronic whiteboard software, and the electronic whiteboard software is web-based electronic whiteboard software used in JS language, or the model object is still a rectangle used in the electronic whiteboard software, and the electronic whiteboard software is client-side electronic whiteboard software used in C # language.
Specifically, the way in which the language model identifies the basic data of the object model is not limited in the embodiment, and is generally determined according to the basic rule when the model object is encoded in the language model. The basic data of the object model is irrelevant to the programming language, and different programming languages adopt the same model definition file and are also irrelevant to the programming language when the language model is generated, so after the language models of different coding languages identify the basic data of the object model, the obtained model objects are completely consistent, and the compatibility of the same object in the same application program under different programming languages is ensured.
According to the technical scheme provided by the embodiment, the language model of the programming language is generated through the model definition file, the language model of the programming language is utilized, the object model basic data of the object to be modeled is converted into the model object under the programming language, the model object of the object to be modeled under the programming language environment can be rapidly generated, the model objects of the same object to be modeled under different programming language environments can be ensured to be consistent through the model definition file, the compatibility of the object to be modeled is further ensured, meanwhile, the model object can be defined by adopting one model definition file under different programming languages, the modeling process is simplified, the development difficulty is reduced, and the utilization rate of the model definition file is improved.
Example two
Fig. 2 is a flowchart of a method for generating a model of an object according to a second embodiment of the present invention. The present embodiment is embodied on the basis of the above-described embodiments. Specifically, generating the language model of the programming language based on the model definition file includes: compiling the model definition file to obtain a syntax tree file; and utilizing a code generation template recognition grammar tree file of the programming language to obtain a language model of the programming language.
Referring to fig. 2, the object code generation method provided in this embodiment specifically includes:
and S210, obtaining a model definition file.
The model definition file is used for defining an object to be modeled.
And S220, compiling the model definition file to obtain a syntax tree file.
Illustratively, a syntax tree may be considered as a tree formed when a model definition file is derived according to a certain rule, which is helpful for understanding the hierarchy of sentence syntax structure in the model definition file. Each node in the syntax tree represents a structure of the model definition file. Generally, a file containing a syntax tree can be referred to as a syntax tree file.
The specific manner of editing the model definition file is not limited in the embodiments. For example, after lexical and grammatical parsing of the model definition file, a grammar tree is constructed from at least one grammar phrase obtained. The specific operation is as follows:
and S221, performing lexical analysis on the model definition file to determine recognizable words contained in the model definition file.
By way of example, lexical analysis is a process of converting a sequence of characters into a sequence of words in computer science, which is a principle of compilation. In short, lexical analysis identifies various types of words according to the lexical rules of the language. Lexical analysis is generally located in the first stage of the compilation process, and in embodiments is located in the first stage of compiling the model definition file. The program or function that performs the lexical analysis is called a lexical analyzer, which may also be called a scanner, and generally exists in the form of a function.
Specifically, during lexical analysis, the model definition file is scanned in a preselected manner. The method comprises the following steps: reading characters in the model definition file in sequence from left to right, and recognizing words with independent meanings in the model definition file by using lexical rules of the language. Where words with independent meaning can be marked as recognizable words, which are typically used by a parser.
S222, carrying out grammar analysis on the recognizable words to form at least one grammar short sentence.
Specifically, the grammar analysis belongs to program editing, and is mainly used for combining recognizable words into various grammar short sentences on the basis of lexical analysis. The program that performs the parsing task is called a parser. Specifically, the grammar analyzer identifies a corresponding grammar category from a lexical analysis result according to grammar rules of the source language to obtain at least one grammar clause. Optionally, the syntax analysis may further determine whether the model definition file is correct in structure, specifically: and when the grammar short sentence is obtained, carrying out grammar check on the grammar short sentence so as to determine whether the model definition file is correct in structure. Further, during parsing, a top-down parsing method may be adopted, or a bottom-up parsing method may also be adopted, which is not limited in the embodiments.
S223, converting at least one grammar short sentence into a grammar tree and forming a corresponding grammar tree file.
Specifically, the nodes of the syntax tree are allocated according to at least one syntax short sentence obtained by syntax analysis, the syntax tree can be obtained after the node allocation is completed, and the syntax tree is further stored to obtain a corresponding syntax tree file.
And S230, generating a template recognition grammar tree file by using codes of the programming language to obtain a language model of the programming language.
The code generation template is a basic rule of the code writing under the programming language, is irrelevant to an object to be coded, and can be understood as a universal rule. It is typically written by a developer and saved and called when needed. Generally, a code generation template of a programming language only needs to be written once and can be reused.
Further, the file format of the code generation template of the programming language is as follows: an EJS file format, an extended Stylesheet Language Transformation (XSLT) format, or a Mustache file format. The EJS is a JavaScript template library which is mainly used for generating an HTML character string from JSON data. When the basic data of the object model is JSON data, the code generation template can adopt a file in an EJS format to ensure that the generated language model accurately identifies the JSON data. XSLT is a language for translating XML documents. When the basic data of the object model is XML data, the code generation template can adopt a file in an XSLT format to ensure that the generated language model can accurately identify the XML data. Mustache is a front-end template engine, and can directly generate HTML of a corresponding module through JSON data. When the basic data of the object model is JSON data, a Mustache file can be selected as the code generation template so as to ensure that the generated language model can accurately identify the JSON data.
Further, after the code generation template identifies the syntax tree file, the rule for calling the object model basic data and the processing rule for calling the object model basic data can be determined, that is, the language model of the programming language is generated, and at this time, the language model can be regarded as the generation method of the model object.
The following describes an exemplary creation process of the language model in the embodiment:
specifically, the programming languages include: c + + language, Java language and JS language, at this time, the corresponding language model includes: a language model of C + +, a language model of Java, and a language model of JS.
Illustratively, FIG. 3 is a block flow diagram of the generation of a language model. Referring to fig. 3, the model definition file is compiled by the compiler 21, wherein the compiler 21 includes three parts: lexical analysis, syntactic analysis, and construction of a syntax tree. Specifically, after the model definition file is input into the compiler 21, the compiler 21 performs lexical analysis on the model definition file to obtain at least one recognizable word, and then uses syntactic analysis to form at least one syntactic short sentence from the at least one recognizable word, and then allocates nodes of the syntactic tree based on the syntactic short sentence to obtain the syntactic tree.
Further, the language model is executed by the model generation module 22. Specifically, the compiler 21 compiles the model definition file and outputs the syntax tree file to the model generation module 22. Further, the model generation module 22 may call the C + + code generation template, the Java code generation template, and the JS code generation template, and respectively identify the syntax tree file by using the three code generation templates to obtain a corresponding C + + language model, a Java language model, and a JS language model, where the language model is a source code in a corresponding programming language. The specific execution sequence of the three code generation templates identifying the syntax tree file is not limited in the embodiment. For example, three code generation templates may simultaneously recognize syntax tree files to simultaneously generate language models for three programming languages. For another example, any one of the three code generation templates is selected to identify the syntax tree file, and after the language model is generated, another code generation template is selected to identify the syntax tree file, and so on, so as to obtain the three language models in sequence.
And S240, acquiring the basic data of the object model of the object to be modeled.
And S250, acquiring a programming language selection instruction.
Specifically, the programming language selection instruction is used to instruct the computer to determine which type of programming language the model object belongs to, which may be determined by the computer according to the programming language environment of the application program, and generally speaking, the programming language selection instruction includes a name or an identifier of at least one programming language. For example, if the current application program can be executed in JS language or C # language, the computer can determine that the programming language selected instruction includes JS language and C # language. As another example, the current application may run in the Java language, and the computer may then determine that the programming language selected instructions include the Java language.
And S260, determining a programming language according to the selected programming language instruction.
Specifically, after the selected instruction of the programming language is analyzed, the selected programming language can be determined, and then the language model of the selected programming language is called to obtain the object model of the object to be selected in the programming language.
S240 may be executed after the execution of S250 and S260 is completed. In addition, the execution sequence of S210-S230 is not limited in the embodiments, and may be executed before, after, or simultaneously with S240, S250, or S260. When S210-S230 is executed before S240 or S250, it is a language model that generates all possible programming languages in advance so as to directly call the language model in the subsequent process. When the S210-S230 is executed after S260, it may be determined whether a language model of a programming language exists, if the language model of the programming language exists, the language model may be directly called, and if the language model of the programming language does not exist, the language model in the programming language may be generated according to S210-S230. This has the advantage that the entire language model does not need to be generated in advance, reducing the computer throughput.
And S270, inputting the basic data of the object model into a language model of the programming language to obtain a model object of the object to be modeled in the programming language.
The model object is generated by converting the basic data of the object model by the language model of the programming language, the model object is used in the application program, and the application program is a program in the programming language environment.
The technical solution provided by this embodiment is to generate a syntax tree file by identifying a model definition file, generate a language model of a programming language by identifying the syntax tree file by a code generation template, convert object model basic data of an object to be modeled into a model object in the programming language by using the language model of the programming language, the model objects of the objects to be modeled can be obtained quickly, and the model objects of the same object to be modeled are consistent under different programming language environments, so as to ensure the compatibility of the objects to be modeled, and simultaneously, since the basic data of the object model is a document, and the code generation template in the language model is a general method, therefore, the model definition file can be considered to associate the general method with the document of the object to be modeled to obtain the model object, and the model object under different programming languages is not required to be defined repeatedly.
The following describes an exemplary method for generating a model of an object provided in the embodiment:
specifically, the object to be modeled is a page of the electronic whiteboard, and the model definition file is recorded as: the TopModel model file has the following specific model definition file:
based on the model definition file, the model definition file includes: the method comprises the steps of describing a document description 'representing page' of an object to be modeled, a name 'Slide' of the object to be modeled when the object to be modeled is stored, defining 'model Slide' of a model of the object to be modeled, and describing, names and definitions of model basic data (such as unique identification, page width, page height, background and the like) contained in the page.
Furthermore, the model definition file is analyzed in a lexical mode and a syntactic mode, a syntactic tree file is constructed, and the syntactic tree file is recognized according to a code generation template so as to obtain a language model of the programming language.
The source code of the language model is as follows:
further, the basic data of the object model is JSON data, which is specifically as follows:
specifically, the basic rule of the model object can be obtained from the language model, and the description is performed by combining the language model and the basic data of the object model by taking the unique identifier, the page width and the element combination as examples. When a model object is created, its unique identification needs to reference an "Id" in the object model base data. The page Width of the model object needs to be according to the numerical value recorded in the Width of the object model basic data. The set of Elements contained in the model object needs to be based on the data set of "Elements" in the object model base data.
Further, the following is a model object generated by the language model recognizing the object model basic data:
the obtained model object can be called by an application program. If a model object of another programming language needs to be obtained, only a corresponding code generation template needs to be called to identify a syntax tree file of the TopModel template file so as to obtain a language model, and then basic data of the object model is input into the language model so as to obtain a corresponding model object without reprogramming a source program of the model object by developers.
