Detailed Description
Methods are provided for a number of particular parameters: groupId, itemId, owner and type. There are also a methods for a searchString that can be a complex expression, containing names and values of one or more fields, for example "owner:username AND title:mygroupname".
A typical usage pattern is:
- Create a new PortalQueryParametersForItems object.
- Optionally set one or more of the properties.
- Use the object by passing it to findItems.
- Obtain the PortalQueryResultSetForItems from the findItemsCompleted signal.
- Optionally call nextQueryParameters to get a new PortalQueryParametersForItems object that can be used to 'find' the next batch of results.
Example: Use query parameters to retrieve web maps with specific tags from a portal.
// webmaps authored prior to July 2nd, 2014 are not supported // so search only from that date to the current time (in milliseconds) QString fromDate = QString("000000%1").arg(QDateTime(QDate(2014, 7, 2)).toMSecsSinceEpoch()); QString toDate = QString("000000%1").arg(QDateTime::currentDateTime().toMSecsSinceEpoch()); PortalQueryParametersForItems query; query.setSearchString(QString("tags:\"%1\" AND +uploaded:[%2 TO %3]") .arg(keyword, fromDate, toDate)); query.setTypes(QList<PortalItemType>() << PortalItemType::WebMap); m_portal->findItems(query);
Example: Obtain the next set of query parameters from a result set:
PortalQueryParametersForItems nextQuery = m_webmapResults->nextQueryParameters(); // check whether the startIndex of the new query is valid if (nextQuery.startIndex() != -1) m_portal->findItems(nextQuery);
Detailed information on search capabilities and syntax can be found in the ArcGIS REST API.
