Interface ExtractedResult

All Superinterfaces:

Iterable<ExtractedItem>

public interface ExtractedResult
extends Iterable<ExtractedItem>

Surfaces the data sent from the server-side XQuery search:search API. Note that the most important function is to provide access to the list of ExtractedItem objects. For example:

    String combinedSearch =
     "<search:search xmlns:search=\"http://marklogic.com/appservices/search\">" +
       "<search:qtext>my search terms</search:qtext>" +
       "<search:options>" +
           "<search:extract-document-data>" +
               "<search:extract-path>/some/path</search:extract-path>" +
               "<search:extract-path>/another/path/*</search:extract-path>" +
           "</search:extract-document-data>" +
       "</search:options>" +
     "</search:search>";
   StringHandle queryHandle = new StringHandle(combinedSearch).withMimetype("application/xml");
   QueryDefinition query = queryMgr.newRawCombinedQueryDefinition(queryHandle);
   SearchHandle results = queryMgr.search(query, new SearchHandle());
   MatchDocumentSummary[] summaries = results.getMatchResults();
   for (MatchDocumentSummary summary : summaries) {
       ExtractedResult extracted = summary.getExtracted();
       if ( Format.XML == summary.getFormat() ) {
           for (ExtractedItem item : extracted) {
               Document extractItem = item.getAs(Document.class);
               ...
           }  }  }

Where you can, of course, use any appropriate StructureReadHandle or corresponding class (provided by that handle’s receiveAs() method) passed to the ExtractedItem.getAs(java.lang.Class<T>) method.

Method Summary

Modifier and Type	Method and Description
String	getKind() The xquery type of the extracted data.
boolean	hasNext() Returns true if internal iterator has more elements.
boolean	isEmpty() Returns true if the underlying node is an “extracted-none” XML element or JSON property.
ExtractedItem	next() Returns the next element in the internal iterator, which is separate from any new iterator created by calls to iterator().
int	size() The number of ExtractedItem objects in the Iterator.

Method Detail

getKind

String getKind()

The xquery type of the extracted data. For XML it will be “element”. For JSON it will be “object” or “array”. Not always available, returns null if unavailable.

Returns:

the xquery type of the extracted data

isEmpty

boolean isEmpty()

Returns true if the underlying node is an “extracted-none” XML element or JSON property.

Returns:

if the underlying node is an “extracted-none” XML element or JSON property

size

int size()

The number of ExtractedItem objects in the Iterator.

Returns:

the number of ExtractedItem object in the Iterator

next

ExtractedItem next()

Returns the next element in the internal iterator, which is separate from any new iterator created by calls to iterator().

Returns:

the next element in the iteration

hasNext

boolean hasNext()

Returns true if internal iterator has more elements. The internal iterator is separate from any new iterator created by calls to iterator().

Returns:

true if the internal iterator has more elements
