• 論文抄録 / 内容記述: Open classes are frequently used in programming languages such as Ruby and Smalltalk to add or change methods of a class that is defined in the same component or in a different one. They are typically used for bug fixing, multi-dimensional separation of concerns, or to modularly add new operations to an existing class. However, they suffer from modularity issues if globally visible: Other components using the same classes are then affected by their modifications. This work presents Extension Classes, a hierarchical approach for dynamically scoping such modifications in Ruby, built on top of ideas from Context-oriented Programming (COP). Our mechanism organizes modifications in classes and allows programmers to define their scope according to a class nesting hierarchy and based on whether programmers regard an affected class as a black box or not. Moreover, Extension Classes support modularizing modifications as mixins, such that they can be reused in other components.; ------------------------------; This is a preprint of an article intended for publication Journal of; Information Processing(JIP). This preprint should not be cited. This; article should be cited as: Journal of Information Processing Vol.25(2017) (online); ------------------------------
