Class ChooseTag

  • All Implemented Interfaces:, IterationTag, JspTag, Tag

    public class ChooseTag
    extends TagSupport

    Tag handler for <choose> in JSTL.

    <choose> is a very simple tag that acts primarily as a container; it always includes its body and allows exactly one of its child <when> tags to run. Since this tag handler doesn't have any attributes, it is common.core to both the rtexprvalue and expression- evaluating versions of the JSTL library.
