org.elasticsearch.script.GeoPointFieldScript

public abstract class GeoPointFieldScript
extends AbstractFieldScript

Script producing geo points. Similarly to what LatLonDocValuesField does, it encodes the points as a long value.

Method Details

leafAdapter

public static GeoPointFieldScript.Factory leafAdapter(Function<SearchLookup,CompositeFieldScript.LeafFactory> parentFactory)

prepareExecute

protected void prepareExecute()

Specified by:

prepareExecute in class AbstractFieldScript

runForDoc

public final void runForDoc(int docId,
 Consumer<GeoPoint> consumer)

Execute the script for the provided docId, passing results to the consumer

lats

public final double[] lats()

Latitude values from the last time AbstractFieldScript.runForDoc(int) was called. This array is mutable and will change with the next call of AbstractFieldScript.runForDoc(int). It is also oversized and will contain garbage at all indices at and above count().

lons

public final double[] lons()

Longitude values from the last time AbstractFieldScript.runForDoc(int) was called. This array is mutable and will change with the next call of AbstractFieldScript.runForDoc(int). It is also oversized and will contain garbage at all indices at and above count().

count

public final int count()

The number of results produced the last time AbstractFieldScript.runForDoc(int) was called.

extractFromSource

protected List<Object> extractFromSource(String path)

Overrides:

extractFromSource in class AbstractFieldScript

emitFromObject

protected void emitFromObject(Object value)

Specified by:

emitFromObject in class AbstractFieldScript

emit

protected final void emit(double lat,
 double lon)
