Design 👍 Fast 67
Design 👍 Fast 👎 Reusability 👎 Method’s or class size
👎 Testability 68

Design 👉 Externalise the constraints 👉 DIC 70
With external constraints 71
The Constraint 72
The Constraint 73
Let’s add an interface ✨ 74
Type definition 75
Type definition 76
Add some tags 77
ServiceLocator 78
The ConstraintValidator (1/2) 79
The ConstraintValidator (2/2) 80
81
TL;DR: 👉 Validate ! ✨ $context->getValidator()->inContext($context) 👉 External constraint :
- Maintainable - Testable - Reusable 👉 _instanceof & !tagged_locator - + default_index_method 82
