All Implemented Interfaces:

ProcessorInterface

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.

Method Detail

init

public void init()

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

Overrides:

init in class ProcessorModule

Parameters:

int - worker id

doPrePart

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

doEndPart

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

reverse

public java.util.Vector reverse(java.util.Vector input,
                                int num)

handle_line

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

Process the HTML for our own extensions

getfile

public final java.lang.String getfile(java.lang.String where)

Parameters:

in: - A string with the location of the to be parsed file

out: - A html-page

do_proc_input

public final void do_proc_input(java.lang.String rq_line,
                                HttpPost poster,
                                java.util.Hashtable proc_var,
                                java.util.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.

maintainance

public void maintainance()

maintainance call, will be called by the admin to perform managment tasks. This can be used instead of its own thread.

Overrides:

maintainance in class Module

calcPage

public java.lang.String calcPage(java.lang.String part2,
                                 scanpage sp,
                                 int cachetype)

processPage

public void processPage(scanpage sp,
                        java.lang.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(java.lang.String uri)

Remove a PageProcess from the list of pages currently being calculated

Parameters:

uri - Uri of the request being calculated

calccrc32

public static int calccrc32(java.lang.String str)
