Class JspContextWrapper

    java.lang.Object
      javax.servlet.jsp.JspContext
          javax.servlet.jsp.PageContext
              org.apache.struts2.jasper.runtime.JspContextWrapper

All Implemented Interfaces:
  javax.servlet.jsp.el.VariableResolver

    public class JspContextWrapper

extends javax.servlet.jsp.PageContext
implements javax.servlet.jsp.el.VariableResolver

Implementation of a JSP Context Wrapper. The JSP Context Wrapper is a JspContext created and maintained by a tag handler implementation. It wraps the Invoking JSP Context, that is, the JspContext instance passed to the tag handler by the invoking page via setJspContext().
