Examples of javax.json.stream.JsonGenerator.writeStartObject()

javax.json.stream.JsonGenerator.writeStartObject()
Writes the JSON start object character. It starts a new child object context within which JSON name/value pairs can be written to the object. This method is valid only in an array context or in no context (when a context is not yet started). This method can only be called once in no context. @return this generator @throws javax.json.JsonException if an i/o error occurs (IOExceptionwould be cause of JsonException) @throws JsonGenerationException if called within object contextor if called more than once in no context

    public void testNestedStructure() throws JSONException {
        JsonGeneratorFactory factory = Json.createGeneratorFactory(null);
        StringWriter w = new StringWriter();
        JsonGenerator gen = factory.createGenerator(w);

                .write("title", "The Matrix")
                .write("year", 1999)
                .writeStartArray("cast")
                .write("Keanu Reaves")
