Class CategoryContextMapping

java.lang.Object

org.elasticsearch.search.suggest.context.ContextMapping

org.elasticsearch.search.suggest.context.CategoryContextMapping

All Implemented Interfaces:

ToXContent

public class CategoryContextMapping
extends ContextMapping

The CategoryContextMapping is used to define a ContextMapping that references a field within a document. The value of the field in turn will be used to setup the suggestions made by the completion suggester.

Throws:

ElasticsearchParseException

toInnerXContent

protected XContentBuilder toInnerXContent(XContentBuilder builder,
                                          ToXContent.Params params)
                                   throws IOException

Description copied from class: ContextMapping

Since every context mapping is assumed to have a name given by the field name of an context object, this method is used to build the value used to serialize the mapping

Specified by:

toInnerXContent in class ContextMapping

Parameters:

builder - builder to append the mapping to

params - parameters passed to the builder

Returns:

the builder used

Throws:

IOException

Description copied from class: ContextMapping

A ContextMapping combined with the information provided by a document form a ContextMapping.ContextConfig which is used to build the underlying FST.

Specified by:

parseContext in class ContextMapping

Parameters:
