2 Forms of Dispatch

• static dispatch - is the process of selecting which implementation of a polymorphic operation (method or function) to call during COMPILE TIME
• dynamic dispatch - is the process of selecting which implementation of a polymorphic operation (method or function) to call at RUNTIME

Advantages of dynamic dispatching

• Develop plug-ins for existing products. No need to recompile the portion of code that relies on the dynamically bonded code
• Create loosely coupled components that are easily unit tested
• Present the same interface by using different implementations (polymorphism)
