ForTokensSupport

public abstract class ForTokensSupport extends javax.servlet.jsp.jstl.core.LoopTagSupport

Support for tag handlers for <forTokens>, the tokenizing iteration tag in JSTL 1.0. This class extends LoopTagSupport and provides ForTokens-specific functionality. The rtexprvalue and expression-evaluating libraries each have handlers that extend this class.
