LoopTag

public interface LoopTag implements javax.servlet.jsp.tagext.Tag

JSTL allows developers to write custom iteration tags by implementing the LoopTag interface. This is not to be confused with javax.servlet.jsp.tagext.IterationTag as defined in JSP 1.2. LoopTag establishes a mechanism for iteration tags to be recognized and for type-safe implicit collaboration with custom subtags.

In most cases, it will not be necessary to implement this interface manually, for a base support class (LoopTagSupport) is provided to facilitate implementation.
