Description

IEnumerable is the generic interface for enumerable containers.

To make your container enumerable, implement the IEnumerable interface. IEnumerable exposes a single method called GetEnumerator, that must return a reference to an IEnumerator interface.

Classes that implement the IEnumerable interface are considered enumerable in Delphi language and can be used in for..in statements.

Note: It is not required that IEnumerable be actually implemented by a class in order to be considered enumerable. It is enough to export a public method called GetEnumerator that returns an enumerator object. Still, we recommend that you implement the IEnumerable interface.
