In computer programming and software design, code refactoring is the process of restructuring existing source code—changing the factoring—without changing its external behavior. Refactoring is intended to improve the design, structure, and/or implementation of the software (its non-functional attributes), while preserving its functionality .
The Byte Code Engineering Library (BCEL) is a project sponsored by the Apache Foundation previously under their Jakarta charter to provide a simple API for decomposing, modifying, and recomposing binary Java classes (I.e. bytecode). The project was conceived and developed by Markus Dahm prior to officially being donated to the Apache Jakarta ...
Rule of three ("Three strikes and you refactor") is a code refactoring rule of thumb to decide when similar pieces of code should be refactored to avoid duplication. It states that two instances of similar code do not require refactoring, but when similar code is used three times, it should be extracted into a new procedure.
Type generalization is a technique commonly used in refactoring.The idea is to draw on the benefits of object-orientation and make more-generalized types, thus enabling more code sharing, leading to better maintainability as there is less code to write.
The first version of IntelliJ IDEA was released in January 2000 and was one of the first available Java IDEs with advanced code navigation and code refactoring capabilities integrated. [6] [7] In 2009, JetBrains released the source code for IntelliJ IDEA under the open-source Apache License 2.0.
CodeLite features project management (workspace/projects), code completion, code refactoring, source browsing, syntax highlighting, Subversion integration, cscope integration, UnitTest++ integration, an interactive debugger built over gdb and a source code editor (based on Scintilla). [6] [7] [8]
However, as more classes are added to a program, especially during maintenance and/or refactoring, the problem of communication between these classes may become more complex. This makes the program harder to read and maintain. Furthermore, it can become difficult to change the program, since any change may affect code in several other classes.
In software engineering, the Extract Class refactoring is applied when a class becomes overweight with too many methods and its purpose becomes unclear. Extract Class refactoring involves creating a new class and moving methods and/or data to the new class.
