(4) if the parent class of the target class is not inquired, a second description container is created, and a second index is established; the second description container of the parent class of the target class is used for storing description information of the parent class of the target class.
Specifically, if the second index does not exist in the parent class of the target class, whether the parent class exists in the parent class of the target class is judged; if the parent class of the target class does not have the parent class, directly creating a second description container and creating a second index, wherein the parent class of the target class may have description information stored in other forms, and the description information of the parent class of the target class may be stored in the second description container when the second description container is created.
In the embodiment of the present application, a possible implementation manner is provided, and the step of obtaining the second description container of the parent class of the target class in step S102 may further include:
(5) if the query obtains the parent class of the target class, taking the parent class of the target class as the parent class of the current target class, and executing the step of obtaining the second description container of the parent class of the target class until the second description container of the parent class of the current target class is established or obtained;
(6) and acquiring a second description container of the parent class of the target class according to the current second description container.
Specifically, if the parent of the target class is obtained through query, the parent of the target class is used as the current parent of the target class, and a step of obtaining a second description container of the parent of the target class is executed, namely, the parent of the target class is circularly operated until the current second description container of the parent of the current target class is obtained; the parent class of the current target class refers to a class having an inheritance relationship with the parent class of the target class.
In a specific implementation process, a specific process of obtaining the second description container of the parent class of the target class according to the current second description container is as follows: and sequentially obtaining the description containers of all subclasses of the parent class of the current target class according to the inheritance relationship until obtaining a second description container of the parent class of the target class.

When the description information of the target class A is received, whether a first index is established in the A is inquired, and if the first index is not established in the target class A, whether a second index is established in a parent class B of the A is inquired; if the second index is not established in the parent class B, inquiring whether the parent class B has a parent class C, if the parent class C is inquired, taking the parent class C as the current parent class B, namely, repeating the operation on the parent class B on the parent class C: querying whether the current parent class B has the current second index, wherein the current parent class B is a parent class C, the current second index is a third index, and querying whether the current second index of the current parent class B is the third index; until a current second index of a parent class of a certain current target class having an inheritance relationship with a parent class B is inquired, obtaining a current second description container, or until the parent class of the certain current target class having the inheritance relationship with the parent class B is inquired without the parent class, directly creating the current second description container of the parent class of the current target class; that is, the fourth index of class D in fig. 3 is queried or the fourth description container D of class D is directly created, and the description containers of the respective subclasses of the parent class of the current object class are sequentially obtained according to the inheritance relationship, as shown in fig. 3, if class D is the parent class of the current object class, the respective subclasses of the parent class of the current object class are class C, class B, and class a, and the description containers of the respective subclasses of the parent class of the current object class are respectively corresponding to the third description container C, the second description container B, and the first description container a, and the description containers of the respective subclasses are sequentially obtained until the second description container of the parent class of the object class is obtained, that is, the third description container C is obtained according to the fourth description container D until the second description container B of the parent class B of the object class a is obtained according to the third description container C.
If the first index of the target class A needs to be obtained, a corresponding second index and a second description container B need to be established by a parent class B of the target class, so that the first description container a can inherit the second description container B; and the second description container B of the parent class B of the target class is established, and the third description container C needs to be established by the node C, so that the second description container B can inherit the third description container C, and by analogy, the first index and the first description container are established, and all the parent classes of the target class need to establish the corresponding description containers and the corresponding indexes.
If the first index is established, it indicates that all parent classes of the target class have already established corresponding indexes and corresponding description containers, that is, if a has already established the first index and the first description container a, B, C and D have already established corresponding description containers and corresponding indexes.

and acquiring the attribute name of the first description container, and creating a first index according to the name of the target class, the name of the first description container and the attribute name of the first description container.
Specifically, the first index may be created by directly adding an attribute to the target class; for example, there is class a, describing container oa, and the attribute name is "__ attr __", and then the corresponding JavaScript code is "a. __ attr __ ═ oa", and in addition, the creation of the first index may also be implemented by other ways, such as a global module and a global container, and is not limited herein.
According to the storage method of the description information, the description information of the target class is stored in the first description container of the target class, the first description container is obtained from the second description container of the parent class of the target class based on the logical inheritance relationship of the classes, the first description container is associated with the target class by adopting the first index, the description information can be searched according to the corresponding inheritance relationship only through the first index of the target class, and the access efficiency can be effectively improved.
Further, the description information of the target class is stored in a first description container, the first description container is associated with the target class by using a first index, and when the description information of the target class is changed, the description information of a subclass having an inheritance relationship with the target class is changed accordingly, so that the description information can be changed along with the inheritance relationship.
