Class JsonObject

  • All Implemented Interfaces:
    Serializable, Cloneable, Map<String,​Object>, Jsonable
    public class JsonObject
extends HashMap<String,​Object>
implements Jsonable
    JsonObject is a common non-thread safe data format for string to data mappings. The contents of a JsonObject are only validated as JSON values on serialization. Meaning all values added to a JsonObject must be recognized by the Jsoner for it to be a true 'JsonObject', so it is really a JsonableHashMap that will serialize to a JsonObject if all of its contents are valid JSON.
    Since:
    2.0.0

    • Constructor Detail

      • JsonObject

        public JsonObject()
        Instantiates an empty JsonObject.

      • JsonObject

        public JsonObject​(Map<String,​?> map)
        Instantiate a new JsonObject by accepting a map's entries, which could lead to de/serialization issues of the resulting JsonObject since the entry values aren't validated as JSON values.
        Parameters:
        map - represents the mappings to produce the JsonObject with.
