All Implemented Interfaces:

SchemaAware, SpatialQueryable

public class LatLonPointSpatialField
extends AbstractSpatialFieldType
implements SchemaAware

A spatial implementation based on Lucene's LatLonPoint and LatLonDocValuesField. The first is based on Lucene's "Points" API, which is a BKD Index. This field type is strictly limited to coordinates in lat/lon decimal degrees. The accuracy is about a centimeter (1.042cm).

Method Detail

checkSupportsDocValues

protected void checkSupportsDocValues()

Description copied from class: FieldType

Called by FieldType.checkSchemaField(SchemaField) if the field has docValues. By default none do.

Overrides:

checkSupportsDocValues in class FieldType

inform

public void inform(IndexSchema schema)

Description copied from interface: SchemaAware

Informs the IndexSchema provided by the schema parameter of an event (e.g., a new FieldType was added, etc.

Specified by:

inform in interface SchemaAware

Parameters:

schema - The IndexSchema instance that inform of the update to.

newSpatialStrategy

protected org.apache.lucene.spatial.SpatialStrategy newSpatialStrategy(String fieldName)

Description copied from class: AbstractSpatialFieldType

Called from AbstractSpatialFieldType.getStrategy(String) upon first use by fieldName. }

Specified by:

newSpatialStrategy in class AbstractSpatialFieldType

decodeDocValueToString

public static String decodeDocValueToString(long value)

Decodes the docValues number into latitude and longitude components, formatting as "lat,lon". The encoding is governed by LatLonDocValuesField. The decimal output representation is reflective of the available precision.

Parameters:

value - Non-null; stored location field data

Returns:

Non-null; "lat, lon"
