With the increase in global informatization speed, computer programming languages are widely used in development work of related persons as a formal language for defining computer programs.
For a computer programming language such as Java, when an application program is to acquire a certain member or make a judgment on a certain member, it is required to acquire the member layer by layer according to a hierarchy. For example, a d object is a member of a c object, a c object is a member of a b object, and a b object is a member of a c object. When the d member of the a object is to be acquired, the application program can be acquired by adopting an if/else judgment mode, namely a, b, c, d is needed to acquire the d member, and none of a, b and c can be empty objects. However, in the above-described hierarchical layer-by-layer acquisition method, when the number of hierarchical layers is large, the code written for the object acquisition method is complex, resulting in low development efficiency.

Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.
The computer programming language may include Java, C, C++, phython, javaScript, and the like as a formal language for defining a computer program. Object acquisition is a common logical process flow in computer programming languages. Several mainstream object acquisition modes will be briefly described below.
Currently, koltin language has a compact writing on the grammar level for object acquisition of a multi-layer class structure, such as a? B? C? D, namely, the object a is not the blank object b, otherwise, returning to null, and so on, so as to obtain the object d. In one embodiment, the multi-layer class structure may also be referred to as a multi-layer structure. The multi-layer class structure may be made up of multiple layers of members that the source object includes. Where a source object refers to an object that includes multiple layers of members. No corresponding syntax and APIs in the Java language support object retrieval for such multi-level class structures, which can only be achieved through some conventional judgment, design mode or Java-based certain properties. For example, the object acquisition of the multi-layer class structure can be realized by using an if/else judgment mode, or the object acquisition of the multi-layer class structure can be realized by using a NullObject design mode to finish multi-layer empty judgment, or the object acquisition of the multi-layer class structure can be realized by using the Optional characteristic of Java 8 through a stream writing method.
However, the aforementioned object acquisition methods require writing out intermediate objects between the source object and the target object during the code writing process. If the intermediate states of the object acquisition modes are too long, for example, hundreds of intermediate objects are included between the source object and the target object, the development efficiency is low because the code written for the object acquisition modes is complex. For example, koltin, if/else, optional may be written as follows:
Furthermore, the Koltin language has a compact writing at the grammar level for object acquisition of the multi-level class structure, but for other Java applications, migration costs are too great if it is not practical to switch to Koltin for this. The mode of using NullObject design mode to complete multi-layer empty judgment requires program development software, such as installing corresponding plug-in on IDEA, and manually adapting the mode in code, so that the configuration process is complicated. Object acquisition using Optional features to achieve a multi-layer class structure requires JDK versions above 1.8, but JDK versions for many applications do not reach 1.8 at present, so adapting such features is not possible. Moreover, the large-scale application upgrade JDK version needs to make a lot of adaptations and bears some upgrade risks, and if the upgrade is not strongly dependent on the high-version JDK, the upgrade to the high-version JDK can occupy more resources of an operating system, so that the upgrade JDK is somewhat inexpensible only for realizing more concise acquisition of key objects of the multi-layer structure.
In order to solve the problems in the prior art, an object acquisition scheme is provided in the embodiment of the present invention, a target object of a multi-layer class structure may be acquired through the identifiers of the source object and the target object, that is, the target object may be acquired from multi-layer members included in the source object through the identifiers of the source object and the target object. The object obtaining scheme may be performed by an electronic device, which may be a terminal or a server. The terminal comprises, but is not limited to, intelligent terminals such as intelligent mobile phones, tablet computers, notebook computers, desktop computers and the like. A server may refer to a server or a cluster of servers. The electronic device can apply the object acquisition scheme to different application scenes according to different programming requirements, for example, the object acquisition scheme can be used in a scene that a multi-layer class structure of Java directly acquires a key object. The object acquisition scheme of the embodiment of the invention can rely on the existing object acquisition function to realize the process of object acquisition according to the identifications of the source object and the target object, and compared with the mode of acquiring the object layer by layer according to the hierarchy in the prior art, the code writing process aiming at the object acquisition of the embodiment of the invention is simpler, thereby improving the development efficiency. In addition, the object acquisition scheme of the embodiment of the invention has the following advantages: (1) Compared with a Koltin-based mode, the object acquisition scheme of the embodiment of the invention can be implemented without language switching or migration, and has higher feasibility; (2) Compared with a NullObject-based mode, the object acquisition scheme of the embodiment of the invention does not need configuration, and is simple to operate; (3) Compared with a Optional-based mode, the object acquisition scheme of the embodiment of the invention can realize more concise acquisition of the key object of the multi-layer class structure under the condition that the application does not need to upgrade the JDK.
In practical application, a developer can refer to the multi-layer class provided in the application program to obtain the extended library of the key object, and then use the method for obtaining the key object by the multi-layer class in the extended library in the application program. The extended library refers to a standard library that provides object acquisition functions. For example, it is necessary to use doSomething method of the member D below the member c below the member b of the object a, and the object acquisition function of the present invention can be abbreviated as D D =func (a, "D") in comparison with the aforementioned writing method of if/else.
The writing method after the expansion library is introduced can be as follows: func is specifically MultilayerAcquisition </SUB >. GETTARGET, at this point,
D d＝MultilayerAcquisition<D>.getTarget(a，“D”)；
d.doSomething()；
Wherein MultilayerAcquisition < >. GETTARGET (, ") is an object acquisition function, D in < D > may refer to the type of object D, a may refer to the source object, and D in" D "may refer to the identity of object D.
Based on the above description, the embodiment of the invention provides an object acquisition method, which can be applied to electronic equipment, and the electronic equipment can be a terminal or a server. The electronic device is installed with an application. Referring to fig. 1, the object obtaining method specifically includes the following steps:
s101, acquiring a call request of an application program for an object acquisition function, wherein the call request comprises identification of a source object and a target object, and the target object is one member of multiple layers of members included by the source object.
Specifically, the application program can call the object acquisition function to acquire the required object, and when the target object needs to be acquired, a call request for the object acquisition function can be initiated, and at this time, the electronic device can detect the call request initiated by the application program for the object acquisition function. The application program may carry the identifications of the source object and the target object in the call request, where the identifications of the source object and the target object may be used as the incoming parameters when the function is acquired by the call object, and the target object is one member of the multiple layers of members included in the source object.
In one embodiment, the identification of the target object may be a full-type name of the target object, which may include directory information and names. For example, the full type name may be in the format of target information. In one embodiment, the full class name may also be referred to as a full class name. The directory information may be a package name, which may be a class name of the target object.
S102, calling the object acquisition function and acquiring the target object from the multi-layer members included in the source object by utilizing the identification of the source object and the target object.
In one embodiment, the object acquisition function includes an object traverser and an object reflection generator, and the specific manner in which the electronic device invokes the object acquisition function and acquires the target object from the multiple layers of members included in the source object by using the identifications of the source object and the target object may be: the electronic equipment calls an object traverser to generate a membership network among multiple layers of members included in the source object; the electronic equipment determines character description of the target object according to the identification of the target object and the membership network; the electronic device passes the identification of the target object and the character description to an object reflection generator to reflect the generated target object. Wherein the character description refers to a character string for describing the target object. The character description of the target object can be conveniently and quickly determined through the relational network, so that the target object is generated.
For example, the source object is object a and the target object is object D. The electronic device may invoke the object traverser to generate a membership network as shown in fig. 2. And the electronic equipment determines the character description of the object D according to the identification of the object D and the membership network. The electronic device passes the identification and character description of object D into an object reflection generator to reflect the generated object D.
In one embodiment, the electronic device may send the identification and character description of the target object to the object reflection generator in a specific manner of generating the target object by reflection, which may be: the electronic equipment transmits the identification and the character description of the target object into an object reflection generator, and the electronic equipment calls an object reflector to generate the target object by reflection technology according to the identification and the character description of the target object.
In one embodiment, the specific manner in which the electronic device invokes the object traverser to generate a membership network between the multiple layers of members included in the source object may be: invoking an object traverser to traverse the source object from top to bottom to obtain the dependency relationship among each member in the multi-layer members included in the source object; a membership network between the multiple layers of members included in the source object is generated from the dependencies.
For example, the electronic device may invoke an object traverser to traverse object a top-down to obtain the dependencies between the various members of the multi-layer members included in object a. As can be seen from fig. 2, the dependency relationships between the members in the multiple layers included in the source object include the dependency relationships among the object a, the object B, the object C1, the dependency relationships among the object a, the object B, the object C, the object D2, and the like. The electronic device may generate a membership network as shown in fig. 2 among the multiple layers of members included in the object a according to the dependency relationship.
In one embodiment, the electronic device may map out a membership network between multiple layers of members included in the source object according to the dependencies. For example, referring to FIG. 2, the membership network can be presented in the form of a tree structure, the source object and the multi-layer members comprised by the source object can be visually represented in the form of nodes, and the dependencies between the multi-layer members can be visually represented in the form of arrows.
In one embodiment, the object obtaining function further includes a decision maker, and the specific manner of determining, by the electronic device, the character description of the target object according to the identifier of the target object and the membership network may be: the electronic equipment determines character descriptions of a plurality of objects according to the identification of the target object and the membership network, and invokes a decision maker to determine the character descriptions of the target object from the character descriptions of the plurality of objects. Wherein the identity of each of the plurality of objects is the same as the identity of the target object. In one embodiment, the decision maker may also be referred to as an intelligent decision maker or an automatic decision maker. By adopting the mode, when the character descriptions of a plurality of objects are determined, the character descriptions of the target objects are determined through the decision maker, so that the obtained character descriptions of the target objects are more accurate and reliable.
In one embodiment, the specific manner in which the electronic device invokes the decision maker to determine the character description of the target object from the character descriptions of the plurality of objects may be: the electronic equipment acquires the type of the target object; the electronic equipment calls a decision maker to determine a first object with the same type as the target object from a plurality of objects, and determines the character description of the first object as the character description of the target object. In one embodiment, the electronic device may obtain the type of the target object from the application, or may also obtain the type of the target object that the call request includes when the call request includes the type of the target object.
In one embodiment, the electronic device may also incorporate context logic of the application program to determine the character description of the target object from the character descriptions of the plurality of objects, thereby achieving the goal of accurately identifying the character description of the target object. For example, the electronic device may determine whether the type of the target object is a type of a target object included in the application, and if so, may trigger the call decision maker to determine, from the plurality of objects, a first object having a type identical to the type of the target object, or trigger determining a character description of the first object as a character description of the target object.
In one embodiment, if the electronic device does not determine the character description of the target object from the character descriptions of the plurality of objects, the abnormality information may be output to prompt the relevant person.
S103, returning the target object to the application program.
In the embodiment of the invention, the electronic equipment can return the target object to the application program, so that the application program can acquire the target object.
In one embodiment, the specific way in which the electronic device returns the target object to the application may be: the electronic equipment acquires each father object of the target object; the electronic equipment judges whether null pointers exist in each father object; if so, the electronic device returns the null pointer to the application.
The electronic equipment can acquire each father object of the target object according to the membership network and judge whether a null pointer exists in each father object; when there is a null pointer to any of the various parent objects, the electronic device may return the null pointer to the application. For example, referring to fig. 2, the electronic device may determine whether or not there is a null pointer for object B and object C, and may return the null pointer to the application when there is a null pointer for either of object B and object C.
In the embodiment shown in fig. 1, the electronic device may obtain a call request of an application program for an object to obtain a function, where the call request includes an identifier of a source object and an identifier of a target object, the target object is one member of multiple layers of members included in the source object, call the object to obtain the function and obtain the target object from the multiple layers of members included in the source object by using the identifiers of the source object and the target object, and return the target object to the application program, so that the object of a specified key member for obtaining the multiple layers of objects can be obtained in one step, writing or judging of a middle layer is omitted, so that a process of obtaining the object by the application program is more concise, and error probability of a developer in writing codes is reduced, thereby improving development efficiency and robustness of the application program.
The object acquisition method according to the embodiment of the present invention will be briefly described with reference to fig. 3 by taking a source object as an object a and a target object as an object D. As shown in fig. 3, when an application invokes an object acquisition function, the identity of object a and object D may be passed into the object acquisition function. The object acquisition function passes these two parameters to the object traverser. The object traverser traverses the source object top-up to generate a membership network for object a. When determining a character description of an object based on the identity of object D and the membership network, the object traverser may send the character description of the object as the character description of the target object to the object reflection generator. When the character descriptions of the plurality of objects are determined according to the identification of the object D and the membership network, the object traverser may send a member list of the plurality of objects to the decision maker, the member list including the identification of each of the plurality of objects and the character description of each of the objects. The decision maker may screen the character description of the final object D from the member list according to the type of the object D and the context logic of the application and send the identity and character description of the final object D to the object reflection generator. In the filtering process, if the ambiguity is confirmed, the abnormal information is output, and if the ambiguity is confirmed, the identification and the character description of the object D are transmitted to the object reflection generator. The object reflection generator generates the object D by reflection technology according to the identification and character description of the final object D, and returns the object D to the application program through the return result of the object acquisition function, so that the application program can acquire the object D. If there is a null pointer in each parent object of object D, such as the upper level object or the upper level object of object D, the object retrieval function will eventually return the null pointer to the application.
When the application program calls the object obtaining function, the process that the application program transmits the identifiers of the object a and the object D into the object obtaining function may correspond to step S101 in the embodiment of fig. 1. The above-described processing of the object traverser to the object reflection generator may correspond to step S102 in the embodiment of fig. 1. The above procedure of confirming ambiguity may refer to that the character descriptions of the target objects cannot be determined from the character descriptions of the plurality of objects. The above procedure of confirming disambiguation may refer to determining a character description of a target object from character descriptions of a plurality of objects. The above-described process of returning the object D to the application by the object reflection generator may correspond to step S103 in the embodiment of fig. 1.
