public class ELIterateTag
extends IterateTag

Custom tag that iterates the elements of a collection, which can be either an attribute or the property of an attribute. The collection can be any of the following: an array of objects, an Enumeration, an Iterator, a Collection (which includes Lists, Sets and Vectors), or a Map (which includes Hashtables) whose elements will be iterated over.

This class is a subclass of the class org.apache.struts.taglib.logic.IterateTag which provides most of the described functionality. This subclass allows all attribute values to be specified as expressions utilizing the JavaServer Pages Standard Library expression language.
