General data type acquisition method in virtual machine, storage medium, equipment and system

Abstract

The invention discloses a general data type acquisition method in a virtual machine, a storage medium, equipment and a system, and relates to the field of data processing.The method comprises the steps that a general data storage model is created, and all types of data of a C + + layer are stored; creating an object array, and storing the type information of the data stored in the general data storage model; obtaining key value information of data stored in the general data storage model and storing the key value information in the created character string array; based on the type information of the data stored in the object array, storing the numerical value information of the data stored in the general data storage model into the object array; and performing interface registration on the C + + layer based on an interface registration mode provided by a virtual machine, wherein the virtual machine calls a registered interface to obtain key value information, type information and numerical value information of the data. According to the invention, the writing number of interfaces can be reduced, and the maintenance workload of the interfaces is effectively reduced.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method for acquiring general data types in a virtual machine, a storage medium, a device and a system. Background technique [0002] In some cases, the result data calculated in the c++ layer needs to be sent to the virtual machine. For example, the calculation or encryption process of the data is executed in the c++ layer, and the result data obtained by the execution needs to be sent to the virtual machine for use. And these result data may have different types, it may be a string type, an integer type, or a floating point type, or it may contain multiple types of result data at the same time, and each result data The types are all different. [0003] For the above situation, the current common solution is to design an interface separately for each situation to adapt to different types of data, resulting in the formation of multiple interfaces with different return data, makin...

[0003] For the above situation, the current common solution is to design an interface separately for each situation to adapt to different types of data, resulting in the formation of multiple interfaces with different return data, making it difficult to maintain the interface, and when there are When new data types are added, new interfaces need to be added accordingly
