  28. def toJsonObject: Any

    Returns a representation of the Stat to be serialized

    Returns a representation of the Stat to be serialized

    This function should return a representation (view) of the Stat to be serialized as JSON. Instances of Map can be used to represent JSON dictionaries or Seq for JSON arrays. A collection.SortedMap such as collection.immutable.ListMap is recommended if key order should be deterministic. Other types may be used but could require the creation and registration of custom serializers dependent on the JSON framework being utilized (currently Gson).

    returns

    stat as a json serializable object

    Tries to remove the given simple feature from the compiled statistics. Note: may not be possible to un-observe a feature, in which case this method will have no effect.
