Class JspFragmentHelper

java.lang.Object
jakarta.servlet.jsp.tagext.JspFragment
org.apache.jasper.runtime.JspFragmentHelper
public abstract class JspFragmentHelper extends JspFragment
Helper class from which all Jsp Fragment helper classes extend. This class allows for the emulation of numerous fragments within a single class, which in turn reduces the load on the class loader since there are potentially many JspFragments in a single page.

The class also provides various utility methods for JspFragment implementations.
