Class ItemContext

java.lang.Object
net.sf.basedb.core.ItemContext

public class ItemContext
extends Object
This item is a helper class for client applications when they need to store information about the current context for plugins that needs to find out the current context of the running client application. It is optional to use this class and it is recommended that plugins and client applications that expects to find context information also can handle situations without any context information. Some of the settings in this objects are saved in the database, some not.

Typical example for using this class are:

A client application storing list/table settings

SessionControl sc = ...
ItemContext current = sc.getCurrentContext(Item.SAMPLE);
current.setRowsPerPage(50);
current.setPage(0);
current.setSortProperty("name");
current.setSortDirection(SortDirection.DESC);
current.setPropertyFilter(
      new PropertyFilter("name", Operator.LIKE, "Nicklas%", Type.STRING)
   );
ItemQuery query = Sample.getQuery();
current.configureQuery(query, true);
// The query will now return the 50 first samples with a
// a name starting with 'Nicklas' sorted in descending order

A client application using filter information when creating new items

SessionControl sc = ...
DbControl dc = sc.newDbControl();
ItemContext current = sc.getCurrentContext(Item.SAMPLE);
Sample sample = Sample.getNew(dc);
if (current.getPropertyValue("name") != null)
{
   sample.setName(current.getPropertyValue("name"));
}
// The name is now 'Nicklas%'

Plugin finds out which items in a list has been selected

SessionControl sc = ...
ItemContext current = sc.getCurrentContext(Item.SAMPLE);
ItemQuery query = Sample.getQuery();
Set selected = current.getSelected();
if (selected != null && selected.size() > 0)
{
   query.restrict(
         Restrictions.in(Hql.property("id"), 
         Expressions.parameter("selected", selected, Type.INT))
      );
)
// The query will now return the selected items only

An import plugin asks client application for a file with a specific file type

public RequestInformation getRequestInformation(GuiContext context, String command)
   throws BaseException
{
   RequestInformation requestInformation = null;
   if (command.equals(Request.COMMAND_CONFIGURE_PLUGIN))
   {
      requestInformation = getConfigurePluginParameters(context);
   }
   else if (command.equals(Request.COMMAND_CONFIGURE_JOB))
   {
      requestInformation = getConfigureJobParameters(context);
      ItemContext fileContext = sc.getCurrentContext(Item.FILE);
      fileContext.setPropertyFilter(FileType.getPropertyFilter(FileType.REPORTER));
   }
   return requestInformation;
