To serialize native container objects such as List and Map objects, you must use Template.

Template objects are pairs of serializer and deserializer. For example, to serialize a List object where the Integer object is an element, you can create a Template object using the following method:

Template listTmpl = Templates.tList(Templates.TInteger);

Class tList, TInteger is a static method, the field is Templates.

A use case for List and Map objects is shown below:
