A Study on Tree-Based Code Extraction Method for Transplantation

Making use of open source software is always a hot topic. Code transplantation is a new idea just proposed for several years, several tools has been built, but no one can solve the problem of open source software transplantation. Abstract syntax tree is a useful way to analyze source code, base on current research, this paper proposes a new method to deal with the code extraction part of transplantation. The experiment result reveals that our method can reduce programmers work of analyze code, make code extraction more convenient and can be used to real word software.
