Interface JsObj

All Superinterfaces:

Iterable<Map.Entry<String,JsElem>>, JsElem, Json<JsObj>, Serializable

public interface JsObj
extends Json<JsObj>, Iterable<Map.Entry<String,JsElem>>

Represents a json object, which is an unordered set of name/element pairs. Two implementations are provided, an immutable which uses the persistent Scala HashMap, and a mutable which uses the conventional Java HashMap.
