Analysis

Overview

This task involves the improvement of org.sophie2.core module.

Task requirements

• Revise org.sophie2.core and add some extra functionality that is needed:
  • Provide a @Lazy annotation for AutoProperties:
    • currently the compute() method is invoked on creation of the AutoProperty
    • @Lazy should be used to implement lazy invocation of the compute() method in the AutoProperty, which means the method will be called on demand
    • this would provide a performance optimization of AutoProperties holding references to objects which potentially will be never used - for instance some GUI object like an "Advanced settings" panel, which the majority of users wouldn't use at all or would use quite seldom
  • Provide a @Const annotation for AutoProperties:
    • @Const must ensure that the compute() method is called only once
• Write appropriate unit tests

Task result

The result of this task should be source code (including unit tests).

Implementation idea

Use reflection for @Const.
