Incomplete objects cause lots of issues.
- Incomplete objects
- Concurrency inconsistencies between creation and essence setting.
Nude Models — Part I : Setters
Ye olde Reliable Data Structures and Their Controversial (Write) Access.
- Pass the object’s essence on creation
The evil powers of mutants
To mutate is to evolve. It was proposed by Sir Charles Darwin and we use it in the software industry. But something is…
- Some persistence frameworks in static typed languages require an empty constructor.
- Stateless objects. Always better solution than static class methods.
Any linter can warn this (possible) situation.
Always create complete objects. Make their essence immutable to endure through time. Every object needs its essence to be a valid one since inception.
Writing a class without its contract would be similar to producing an engineering component (electrical circuit, VLSI (Very Large Scale Integration) chip, bridge, engine…) without a spec. No professional engineer would even consider the idea.
