Container traversing method and device

Abstract

The embodiment of the invention provides a container traversing method and device, and the method comprises the steps: carrying out the de-nesting of a to-be-traversed nesting container, and obtainingthe types of a plurality of containers; Wherein the nesting container is a container obtained by nesting a plurality of containers. Traversing the content of the nested container according to the traversing template corresponding to the type of each container; Wherein the traversal template is a code used for traversing the content of the container of the corresponding type. According to the embodiment, the code writing workload can be reduced, and the container traversal flexibility can be improved.

Description

technical field [0001] Embodiments of the present invention relate to computer technology, and in particular to a method and device for traversing containers. Background technique [0002] A container is a commonly used tool in C++. In the process of operating a program containing a container, it is often necessary to traverse the contents of the container to achieve the corresponding operation. [0003] When traversing the content of the container in the prior art, it is usually necessary to first determine the type of the container and the type of the sub-elements contained in the container, and then write the corresponding code according to the type of the container and the type of the sub-elements contained in the container, for the nested type Containers need to use multi-layer loops to traverse the containers. [0004] However, for containers of different nesting types, different codes must be written to achieve traversal. Not only the code writing workload is heavy, ...
