摘要: In the software engineering literature, many works claim that use of design patterns improves comprehensibility programs and, more generally, their maintainability. Yet, little work attempted to study impact on developers' tasks program comprehension and modification. We perform an experiment collect data Visitor pattern modification with class diagrams. eye-tracker register saccades fixations, latter representing focus attention. Collected show plays a role in maintenance tasks: diagrams its canonical representation requires less efforts from developers.
