#if("$!{request.xpage}" == 'plain')
  $response.setContentType('application/json')
#end
##==============================
## Offset = item # at which to start displaying data
##==============================
#set($offset = $util.parseInt($request.get('offset')))
## offset starts from 0 in velocity and 1 in javascript
#set($offset = $offset - 1)
#if($offset < 0)
  #set($offset = 0)
#end
##==================
## Limit = # of items to display
##==================
#set($limit = $util.parseInt($request.get('limit')))
##====================================
## Step1: Transform Map into list, one list item per link/page
##====================================
#set ($states = $services.linkchecker.getLinkStates())
#set ($stateList = [])
#foreach ($link in $states.keySet())
  #set ($pages = $states.get($link))
  #foreach ($page in $pages.keySet())
    #set ($tmpMap = {})
    #set ($dummy = $tmpMap.put("link", $link))
    #set ($dummy = $tmpMap.put("page", $page))
    #set ($dummy = $tmpMap.put("code", $pages.get($page).getResponseCode()))
    #set ($dummy = $tmpMap.put("date", $datetool.format($pages.get($page).getLastCheckedTime())))
    #set ($dummy = $stateList.add($tmpMap))
  #end
#end
##============
## Step2: Filter the list
##============
#set ($filteredList = [])
#set ($linkFilter = "$!{request.get('link')}")
#set ($pageFilter = "$!{request.get('page')}")
#set ($codeFilter = "$!{request.get('code')}")
#set ($dateFilter = "$!{request.get('date')}")
#foreach ($entry in $stateList)
  #set ($codeString = "$entry.get('code')")
  #if ($codeFilter.startsWith("!") && $codeFilter.length() > 1)
    #set ($codeMatch = !$codeString.contains($codeFilter.substring(1)))
  #else
    #set ($codeMatch = $codeString.contains($codeFilter))
  #end
  #if ($entry.get("link").contains($linkFilter) && $entry.get("page").contains($pageFilter) && $codeMatch && $entry.get("date").contains($dateFilter))
    #set ($dummy = $filteredList.add($entry))
  #end
#end
##===================
## Step3: Handle offset and limit
##===================
#set ($added = 0)
#set ($resultList = [])
#if ($offset < $filteredList.size())
  #set ($toIndex = $mathtool.min($mathtool.add($offset, $limit), $filteredList.size()))
  #set ($resultList = $filteredList.subList($offset, $toIndex))
#end

## JSON Generation
