Query for Components

Using Criteria

In this sample we are searching for Components in a given Publication. Therefore we define two search criteria:

• PublicationCriteria - to limit result to the given Publication ID;
• ItemTypeCriteria - to limit results to only type Component;

We then perform a logical AND between these criteria and feed that into the Query.

    String items[] = query.executeQuery();

    out.println("<p><b>Simple Query: </b>" + list(items) + "</p>");

    PublicationCriteria publicationCriteria = new PublicationCriteria(83);

    query.setCriteria(publicationCriteria);

    items = query.executeQuery();

    out.println("<p><b>Publication=83 Query: </b>" + list(items) + "</p>");

    ItemTypeCriteria itemTypeCriteria = new ItemTypeCriteria(ItemTypes.COMPONENT);

    AndCriteria andCriteria = new AndCriteria(publicationCriteria, itemTypeCriteria);

    query.setCriteria(andCriteria);

    items = query.executeQuery();

    out.println("<p><b>Publication=83 AND ItemType=16 Query: </b>" + list(items) + "</p>");
