As I mentioned earlier, In C , the template method is used extensively through predefined interfaces, one such interface is IComparable. It is defined in the IComparable interface, which many predefined C types already implement. For example, CompareTo is available for integers and strings. Because our sort methods are meant to be general, we declare that the item types must implement the interface using:.

Any class can do so if it provides a CompareTo method. So, inside a Person class, we have to implement the IComparable interface like this:. But how is CompareTo defined in terms of CompareTo? Well, we are looking at names, so the name will presumably be a string. CompareTo is defined for strings so that is what will be called. The check for the type of the object is necessary because the implementation of CompareTo must match its interface, which is defined on the object.

When a Template Method uses an interface for specifying the primitive operations, the classes must implement those operations. Contents Exit focus mode. Is this page helpful? Please rate your experience Yes No. Any additional feedback? Submit and view feedback for This product This page.
