Intent
Defines the skeleton of an algorithm in an operation, deferring some steps to sub classes. Template Method sub-classes redefine certain steps of an algorithm without changing the algorithms structure.
Why is this used?
This ensures the algorithm's structure stays unchanged, while sub classes provide some part of the implementation.
Why is this used?
This ensures the algorithm's structure stays unchanged, while sub classes provide some part of the implementation.
How is this applied?
- An abstract class will contain the template methods
- This will then be used as abstract versions of the operations used in the template method
- There may well be many sub classes that want to implement the full set of operations in the template method
