Examples of org.codehaus.jackson.JsonGenerator.writeObject()

org.codehaus.jackson.JsonGenerator.writeObject()
Method for writing given Java object (POJO) as Json. Exactly how the object gets written depends on object in question (ad on codec, its configuration); for most beans it will result in Json object, but for others Json array, or String or numeric value (and for nulls, Json null literal. NOTE: generator must have its object codec set to non-null value; for generators created by a mapping factory this is the case, for others not.

          g.writeStartObject();
          g.writeFieldName("__cmds");
          g.writeStartArray();
          List<Object> functions = new ArrayList<Object>(context.getFunctions());
          for (Object function : functions) {
            g.writeObject(function);
          }
          g.writeEndArray();
          g.writeEndObject();
          g.close();
        }
