public class MapToArrayDefaultFirst
extends DynamoServlet

This droplet is used to convert a map of items to a sorted array of map entries with the default item in the beginning of the array. The default item is specified either through defaultId parameter (only for repository items) or through defaultKey parameter that is the map key that corresponds to the default item.

The droplet is primarily intended to sort shipping addresses or credit cards so that the default address or card is displayed as the first item on the JSP page.

If sortByKeys parameter is set to true then the returning array will be sorted by keys otherwise an unsorted array will be returned. In the case of a null map, the returning array would be null.

This droplet takes the following parameters

defaultId

The parameter that defines the repositoryId of the default item. Can be used only for repository item, for other types of objects like ShippingGroup the defaultKey parameter should be used.

defaultKey

The parameter that defines the map key of the default item that should be placed in the beginning of the array.

sortByKeys

Boolean that specifies whether to sort map entries by keys or not.

map

The parameter that defines the map of items to convert to the sorted array.

Example

  <dsp:droplet name="MapToArrayDefaultFirst">
     <param name="defaultId" value="Profile.shippingAddress.repositoryId"/>
     <param name="map" value="Profile.secondaryAddresses"/>
     <oparam name="output">
        <dsp:droplet name="ForEach">
           <param name="array" value="sortedArray"/>
           <oparam name="output">
              key: &ltdsp:valueof param="element.key"/&gt
              address city: <dsp:valueof param="element.value.city"&gt/>
           </oparam>
        </dsp:droplet>
     </oparam>>
  </droplet>

Method Detail

service

public void service(DynamoHttpServletRequest pRequest,
           DynamoHttpServletResponse pResponse)
             throws javax.servlet.ServletException,
                    java.io.IOException

See the class documentation above.

Overrides:

service in class DynamoServlet

Parameters:

pRequest - - http request

pResponse - - http response

Throws:

javax.servlet.ServletException - if an error occurs

java.io.IOException - if an error occurs

getSortedArray

protected java.lang.Object[] getSortedArray(java.util.Map pMap,
                                java.lang.String pDefaultKey,
                                boolean pSortByKeys,
                                DynamoHttpServletRequest pRequest)

Converts the map to the array of map entries with the default one in the beginning of the array. If pSortByKeys boolean is true then map entries are sorted by keys.

Parameters:

pMap - - the map to convert to the sorted array

pDefaultKey - - the map key that corresponds to the default item

pSortByKeys - - boolean that specifies whether to sort items by keys or not

pRequest - - the http request

Returns:

Object[] sorted array of items

getDefaultMapKey

protected java.lang.String getDefaultMapKey(java.util.Map pMap,
                                java.lang.String pDefaultId)

Taken the map of repository items and default ID value returns a map key that corresponds to the item with the specified repository ID. This method is intended for the map of repository items only. For maps of objects different from repository items returns null.

Parameters:

pMap - - map of repository items to check

pDefaultId - - default id

Returns:

the map key that corresponds to the item with default ID or null if the map holds objects different from repository items or default ID is not specified.
