org.apache.cocoon.taglib.core.LoopTagSupport
   org.apache.cocoon.taglib.core.ForEachSupport

All known Subclasses:   org.apache.cocoon.taglib.jxpath.core.ForEachTag,
ForEachSupport
abstract public class ForEachSupport extends LoopTagSupport (Code)

Support for tag handlers for <forEach>, the core iteration tag in JSTL 1.0. This class extends LoopTagSupport and provides ForEach-specific functionality. The rtexprvalue library and the expression-evaluating library each have handlers that extend this class.

Localized here is the logic for handling the veritable smorgasbord of types supported by <forEach>, including arrays, Collections, and others. To see how the actual iteration is controlled, review the org.apache.cocoon.taglib.core.LoopTagSupport class instead.
