Description

Implement the IEnumerator interface in the class that has to act as an enumerator for a container. An IEnumerator is usually obtained by a call to the container's GetEnumerator method.

Classes that implement the IEnumerator interface are considered enumerators in Delphi language and are used automatically by the for..in statement.

Note: It is not required that IEnumerator be actually implemented by a class in order to be considered an enumerator. It is enough to simply implement the required methods in your class. Still, we recommend that you implement the IEnumerator interface.
