singleton-controlled-global-access

Status: OUT

Singleton provides controlled global access that systematically improves on raw global/static objects across four dimensions: lazy initialization avoids premature construction, the Instance() method controls the creation point, a registry enables subclass selection without modifying clients, and the pattern permits future evolution to multiple instances.

Justifications

Four base beliefs about Singleton's advantages unify into a single controlled-access thesis

Depends on (SL): singleton-lazy-initialization-pattern, singleton-more-flexible-than-static-methods, singleton-not-global-static-object-cpp, singleton-registry-for-subclass-selection
