An Automatic Refactoring Method for Object-Oriented Software

Abstract

The invention provides an automatic reconstruction method for object-oriented software and relates to the technical field of improving software quality. This method builds the software system to be reconstructed into a class-level multi-layer dependent directed network model, performs reconstruction preprocessing, merges class-level network connectivity slices, converts each class-level network connectivity slice into a collection of entities of the same type, and analyzes Semantic and structural coupling relationships between the elements of each entity set, construct a method-level coupled undirected network model, determine the weight coefficients of different types of coupling relationships between nodes in the undirected network, divide each method-level network into communities, and generate complex According to the construction suggestions, the software system to be refactored should be refactored. This invention starts from the perspective of global cohesion and coupling of the entire software system, combines semantic similarity, structural similarity and hierarchical clustering algorithm to simultaneously generate relocation functions, relocation attributes and refining class reconstruction operation suggestions, effectively improving the code's reliability. Understandability, reusability and maintainability.

Description

[0001] Technical field: [0002] The invention relates to the technical field of software quality improvement, in particular to an automatic reconfiguration method for object-oriented software. [0003] Background technique: [0004] In the process of software development and maintenance, constantly changing requirements cause the original design structure of the system to be broken, making the structure more confusing, the code difficult to understand, and software reuse and maintenance becoming more and more difficult. Software refactoring is an important means to improve software quality. It improves the comprehensibility, maintainability and scalability of software by adjusting the internal structure of software without changing the external behavior of the software. However, software refactoring is a time-consuming and complex code adjustment activity that requires software developers to perceive the code as a whole and make complex decisions about "where, when, and how" t...

[0008] (3) Too large class (God Class): The class contains too many functions and attributes, and realizes too many functions, resulting in poor code comprehensibility and readability

[0010] The above algorithm can only implement a single refactoring operation to improve the cohesion of the system, and the refactoring operations of the refining class are all semi-automatic algorithms, requiring developers to manually input the categories that need to be decomposed for further analysis. certain limitations
