    Modifier and Type
    Field
    Description
    static final NestedLookup
    EMPTY
    A NestedLookup for a mapping with no nested mappers

  • Method Summary

    Modifier and Type
    Method
    Description
    static NestedLookup
    build(List<NestedObjectMapper> mappers)
    Construct a NestedLookup from a list of NestedObjectMappers
    Map<String,NestedObjectMapper>
    getNestedMappers()
     
    String
    getNestedParent(String path)
    Given a nested object path, returns the path to its nested parent In particular, if a nested field `foo` contains an object field `bar.baz`, then calling this method with `foo.bar.baz` will return the path `foo`, skipping over the object-but-not-nested `foo.bar`
    Map<String,org.apache.lucene.search.Query>
    getNestedParentFilters()
