Examples of org.openx.data.jsonserde.json.JSONObject$Null

org.openx.data.jsonserde.json.JSONObject
JSONObject.NULL is equivalent to the value that JavaScript calls null, whilst Java's null is equivalent to the value that JavaScript calls undefined.

        JsonSerDe serde = getNumericSerde();
        Text line = new Text("{ cfloat:3.1415E02, cdouble:-1.65788E-12}");
