All Implemented Interfaces:

Descriptor

public class scanparser
extends ProcessorModule

scanpage is a container class it holds all objects needed per scan page it was introduced to make servscan threadsafe but will probably in the future hold all page related info instead of HttpServletR equest and HttpServletResponse because we want extend the model of offline page generation.

public scanparser()

Method Detail

init

public void init()

Init the servscan, this is needed because it was created using a newInstanceOf().

Overrides:

init in class ProcessorModule

getMimeType

public String getMimeType(String ext)

getMimeType: Returns the mimetype using ServletContext.getServletContext which returns the servlet context which is set when servscan is loaded. Fixed on 22 December 1999 by daniel & davzev.

Parameters:

ext - A String containing the extension.

Returns:

The mimetype.

getMimeTypeFile

public String getMimeTypeFile(String fileName)

doPrePart

public String doPrePart(String template,
                        int last,
                        int rpos,
                        int numitems,
                        int epos)

doEndPart

public String doEndPart(String template,
                        int last,
                        int rpos,
                        int numitems,
                        int epos)

reverse

public Vector reverse(List input,
                      int num)

do_vals

boolean do_vals(String cmd,
                sessionInfo session,
                scanpage sp)
          throws ParseException

Throws:

ParseException

do_val

boolean do_val(String cmd,
               sessionInfo session,
               scanpage sp)
         throws ParseException

Throws:

ParseException

handle_line

public final String handle_line(String body,
                                sessionInfo session,
                                scanpage sp)
                         throws ParseException

Process the HTML for our own extensions

Throws:

ParseException

getfile

public final String getfile(String where)

Parameters:

where - A string with the location of the to be parsed file

Returns:

A html-page

do_conditions_lif

String do_conditions_lif(String body,
                         sessionInfo session,
                         scanpage sp)
                   throws ParseException

handle if/then/elseif/\/if

Throws:

ParseException

do_if

String do_if(String body,
             sessionInfo session,
             scanpage sp)
       throws ParseException

Throws:

ParseException

do_conditions

String do_conditions(String body,
                     sessionInfo session,
                     scanpage sp)
               throws ParseException

handle if/then/elseif/\/if

Throws:

ParseException

getRoots

Hashtable getRoots()

do_proc_input

public final void do_proc_input(String rq_line,
                                HttpPost poster,
                                Hashtable proc_var,
                                Hashtable proc_cmd,
                                scanpage sp)

This does the handling of the Form inputs. It calls the processor to handle the PRC-CMD's it finds after it has done the PRC-VAR's fill in.

calcPage

public String calcPage(String part2,
                       scanpage sp,
                       int cachetype)

processPage

public void processPage(scanpage sp,
                        String uri)

Start a process to calculate a page in the background used by scancache to generate new pages for expired ones

Parameters:

sp - The request of the page (duplicated from the original)

uri - The uri of the request

removeProcess

public void removeProcess(String uri)

Remove a PageProcess from the list of pages currently being calculated

Parameters:

uri - Uri of the request being calculated

doMAlphaSort

Vector doMAlphaSort(List input,
                    String sortonnumbers,
                    int numberofitems)

davzev changed method syntax from int sortonnumber to String sortonnumbers. Sort the lines in the vector, to do this we need to first group them and then sort them by item number defined

Parameters:

input - - the result Vector unsorted.

sortonnumbers - - a String with colpositions eg. "6:4" denoting the order and colpositions for the sort.

numberofitems - - integer with the amount of items.

Returns:

a Vector with sorted items.
