System and method for automatically identifying compound refactorings of program code through quantitative metric analysis

摘要

A system and method for automatically identifying compound refactorings of program code through quantitative metric analysis is presented. Program code is maintained, including program statements written in accordance with a programming language and defining operations executed following transformation into machine code. Compound refactorings are built. The program code is refactored by evaluating one or more of the program statements against a compound refactoring including a set of one or more individual refactorings. The application of the refactorings to the program statements is validated for each evaluated refactoring. A quantitative measure is analyzed against a threshold to reflect a relative difference between the program statements prior to and after application of the refactorings.
