    • extractRawValues

      public static java.util.List<java.lang.Object> extractRawValues​(java.lang.String path, java.util.Map<java.lang.String,​java.lang.Object> map)
      Extracts raw values (string, int, and so on) based on the path provided returning all of them as a single list.

    • extractValue

      public static java.lang.Object extractValue​(java.util.Map<?,​?> map, java.lang.String... pathElements)

    • filter

      public static java.util.Map<java.lang.String,​java.lang.Object> filter​(java.util.Map<java.lang.String,​?> map, java.lang.String[] includes, java.lang.String[] excludes)
      Only keep properties in map that match the includes but not the excludes. An empty list of includes is interpreted as a wildcard while an empty list of excludes does not match anything. If a property matches both an include and an exclude, then the exclude wins. If an object matches, then any of its sub properties are automatically considered as matching as well, both for includes and excludes. Dots in field names are treated as sub objects. So for instance if a document contains a.b as a property and a is an include, then a.b will be kept in the filtered map.

      Returns a function that filters a document map based on the given include and exclude rules.
