JspFragment

Synopsis

The JspFragment class represents an object that encapsulates a set of JSP actions and/or EL expressions, possibly mixed with template text, that a tag handler can invoke as many times as needed. The container creates an instance of this class for the body of a custom action implemented by a simple tag handler, as well as for the body of the <jsp:attribute> for an attribute of type JspFragment.
