Title
Systematic Change of Data Representation: Program Manipulations and a Case Study
Abstract
We present a set of semantics-based program manipulation techniques to assist in restructuring software encapsulation boundaries and making systematic changes to data representations. These techniques adapt abstraction structure and data representations without altering program functionality. The techniques are intended to be embodied in source-level analysis and manipulation tools used interactively by programmers, rather than in fully automatic tools and compilers. The approach involves combining techniques for adapting and specializing encapsulated data types (classes) and for eliminating redundant operations that are distributed among multiple methods in a class (functions in a data type) with techniques for cloning classes to facilitate specialization and for moving computation across class boundaries. The combined set of techniques is intended to facilitate revision of structural design decisions such as the design of a class hierarchy or an internal component interface. The paper introduces new techniques, provides soundness proofs, and gives details of case study involving production Java code.
