public ApplicationFilterChain() 
{
        super();
}

Construct a new chain instance with no defined filters.

  void addFilter(ApplicationFilterConfig filterConfig) 
{
        if (n == filters.length) {
            ApplicationFilterConfig[] newFilters =
                new ApplicationFilterConfig[n + INCREMENT];
            System.arraycopy(filters, 0, newFilters, 0, n);
            filters = newFilters;
        }
        filters[n++] = filterConfig;
}

Add a filter to the set of filters that will be executed in this chain.

 public  void doFilter(ServletRequest request,
    ServletResponse response) throws IOException, ServletException 
{
        if( Globals.IS_SECURITY_ENABLED ) {
            final ServletRequest req = request;
            final ServletResponse res = response;
            try {
                java.security.AccessController.doPrivileged(
                    new java.security.PrivilegedExceptionAction() {
                        public Object run() 
                            throws ServletException, IOException {
                            internalDoFilter(req,res);
                            return null;
                        }
                    }
                );
            } catch( PrivilegedActionException pe) {
                Exception e = pe.getException();
                if (e instanceof ServletException)
                    throw (ServletException) e;
                else if (e instanceof IOException)
                    throw (IOException) e;
                else if (e instanceof RuntimeException)
                    throw (RuntimeException) e;
                else
                    throw new ServletException(e.getMessage(), e);
            }
        } else {
            internalDoFilter(request,response);
        }
}

Invoke the next filter in this chain, passing the specified request and response. If there are no more filters in this chain, invoke the service() method of the servlet itself.

 public  void doFilterEvent(CometEvent event) throws IOException, ServletException 
{
        if( Globals.IS_SECURITY_ENABLED ) {
            final CometEvent ev = event;
            try {

                    new java.security.PrivilegedExceptionAction() {
                        public Object run() 
                            throws ServletException, IOException {
                            internalDoFilterEvent(ev);
                            return null;
                        }
                    }
                );
            } catch( PrivilegedActionException pe) {
                Exception e = pe.getException();
                if (e instanceof ServletException)
                    throw (ServletException) e;
                else if (e instanceof IOException)
                    throw (IOException) e;
                else if (e instanceof RuntimeException)
                    throw (RuntimeException) e;
                else
                    throw new ServletException(e.getMessage(), e);
            }
        } else {
            internalDoFilterEvent(event);
        }
}

Invoke the next filter in this chain, passing the specified request and response. If there are no more filters in this chain, invoke the service() method of the servlet itself.

 public static ServletRequest getLastServicedRequest() 
{
        return (ServletRequest) lastServicedRequest.get();
}

The last request passed to a servlet for servicing from the current thread.

 public static ServletResponse getLastServicedResponse() 
{
        return (ServletResponse) lastServicedResponse.get();
}

The last response passed to a servlet for servicing from the current thread.

  void release() 
{
        for (int i = 0; i <  n; i++) {
            filters[i] = null;
        }
        n = 0;
        pos = 0;
        servlet = null;
        support = null;
}

Release references to the filters and wrapper executed by this chain.

  void reuse() 
{
        pos = 0;
}

Prepare for reuse of the filters and wrapper executed by this chain.

  void setServlet(Servlet servlet) 
{
        this.servlet = servlet;
}

Set the servlet that will be executed at the end of this chain.

  void setSupport(InstanceSupport support) 
{
        this.support = support;
}

Set the InstanceSupport object used for event notifications for this filter chain.
