Study Notes
Open-Closed Principle (OCP)
- Software entities should be open for extension but closed for modification.
Origin of the Term
- The term "open-closed principle" was originated by Bertrand Meyer.
Resolving the Dilemma
- Abstraction is the technique used to resolve the apparent dilemma in the open-closed principle.
SOLID Principles
- The open-closed principle is one of the five SOLID principles of object-oriented design.
Module Openness
- According to Meyer's open-closed principle, for a module to be 'open' means it is open to extension, but closed to modification.
