    Modifier and Type Field Description
    static java.util.function.Function<java.lang.String,​java.util.function.Predicate<java.lang.String>> NOOP_FIELD_FILTER

  • Method Summary

    Modifier and Type Method Description
    default java.util.function.Function<java.lang.String,​java.util.function.Predicate<java.lang.String>> getFieldFilter()
    Returns a function that given an index name returns a predicate which fields must match in order to be returned by get mappings, get index, get field mappings and field capabilities API.
    default java.util.Map<java.lang.String,​Mapper.TypeParser> getMappers()
    Returns additional mapper implementations added by this plugin.
    default java.util.Map<java.lang.String,​MetadataFieldMapper.TypeParser> getMetadataMappers()
    Returns additional metadata mapper implementations added by this plugin.
  • Field Details

    • NOOP_FIELD_PREDICATE

      static final java.util.function.Predicate<java.lang.String> NOOP_FIELD_PREDICATE
      The default field predicate applied, which doesn't filter anything. That means that by default get mappings, get index get field mappings and field capabilities API will return every field that's present in the mappings.
    • NOOP_FIELD_FILTER

      static final java.util.function.Function<java.lang.String,​java.util.function.Predicate<java.lang.String>> NOOP_FIELD_FILTER
      The default field filter applied, which doesn't filter anything. That means that by default get mappings, get index get field mappings and field capabilities API will return every field that's present in the mappings.

    • getMappers

      default java.util.Map<java.lang.String,​Mapper.TypeParser> getMappers()
      Returns additional mapper implementations added by this plugin.

      The key of the returned Map is the unique name for the mapper which will be used as the mapping type, and the value is a Mapper.TypeParser to parse the mapper settings into a Mapper.

    • getMetadataMappers

      default java.util.Map<java.lang.String,​MetadataFieldMapper.TypeParser> getMetadataMappers()
      Returns additional metadata mapper implementations added by this plugin.

      The key of the returned Map is the unique name for the metadata mapper, which is used in the mapping json to configure the metadata mapper, and the value is a MetadataFieldMapper.TypeParser to parse the mapper settings into a MetadataFieldMapper.

    • getFieldFilter

      default java.util.function.Function<java.lang.String,​java.util.function.Predicate<java.lang.String>> getFieldFilter()
      Returns a function that given an index name returns a predicate which fields must match in order to be returned by get mappings, get index, get field mappings and field capabilities API. Useful to filter the fields that such API return. The predicate receives the field name as input argument and should return true to show the field and false to hide it.
