Class GeoContextMapping

java.lang.Object

org.elasticsearch.search.suggest.completion.context.ContextMapping<GeoQueryContext>

org.elasticsearch.search.suggest.completion.context.GeoContextMapping

All Implemented Interfaces:

org.elasticsearch.common.xcontent.ToXContent, org.elasticsearch.common.xcontent.ToXContentFragment

public class GeoContextMapping
extends ContextMapping<GeoQueryContext>

A ContextMapping that uses a geo location/area as a criteria. The suggestions can be boosted and/or filtered depending on whether it falls within an area, represented by a query geo hash with a specified precision GeoQueryContext defines the options for constructing a unit of query context for this context type

                                                                     throws IOException

Description copied from class: ContextMapping

Implementations should add specific configurations that need to be persisted

Specified by:

toInnerXContent in class ContextMapping<GeoQueryContext>

Throws:

IOException

parseContext

public Set<String> parseContext(ParseContext parseContext,
 org.elasticsearch.common.xcontent.XContentParser parser)
                         throws IOException,
ElasticsearchParseException

Parse a set of CharSequence contexts at index-time. Acceptable formats:

• Array:

  [<GEO POINT>, ..]

• String/Object/Array:

  "GEO POINT"

see GeoPoint(String) for GEO POINT

Specified by:

parseContext in class ContextMapping<GeoQueryContext>

Throws:

IOException

ElasticsearchParseException

parseContext

public Set<String> parseContext(LuceneDocument document)

Description copied from class: ContextMapping

Retrieves a set of context from a document at index-time.

Specified by:

parseContext in class ContextMapping<GeoQueryContext>

fromXContent

protected GeoQueryContext fromXContent(org.elasticsearch.common.xcontent.XContentParser parser)
                                throws IOException

Description copied from class: ContextMapping

Prototype for the query context

Specified by:

fromXContent in class ContextMapping<GeoQueryContext>

Throws:

IOException

toInternalQueryContexts

public List<ContextMapping.InternalQueryContext> toInternalQueryContexts(List<GeoQueryContext> queryContexts)

Parse a list of GeoQueryContext using parser. A QueryContexts accepts one of the following forms:

• Object: GeoQueryContext
• String: GeoQueryContext value with boost=1 precision=PRECISION neighbours=[PRECISION]
• Array:

  [GeoQueryContext, ..]

A GeoQueryContext has one of the following forms:

• Object:

  • GEO POINT

  • {"lat": <double>, "lon": <double>, "precision":
             <int>, "neighbours": <[int, ..]>}

  • {"context": <string>, "boost": <int>, "precision":
             <int>, "neighbours": <[int, ..]>}

  • {"context": <GEO POINT>, "boost": <int>, "precision":
             <int>, "neighbours": <[int, ..]>}

• String:

  GEO POINT

see GeoPoint(String) for GEO POINT

Specified by:

toInternalQueryContexts in class ContextMapping<GeoQueryContext>

validateReferences

public void validateReferences(Version indexVersionCreated,
 Function<String,MappedFieldType> fieldResolver)

Description copied from class: ContextMapping

Checks if the current context is consistent with the rest of the fields. For example, the GeoContext should check that the field that it points to has the correct type.

Overrides:

validateReferences in class ContextMapping<GeoQueryContext>

equals

public boolean equals(Object o)

Overrides:

equals in class ContextMapping<GeoQueryContext>

hashCode

public int hashCode()

Overrides:

hashCode in class ContextMapping<GeoQueryContext>
