Interface representing a movies
Trailer data transfer object.
The methods of this class provide easy access to all trailer related data which was returned by the remote
service in JSON format. Please note that, as the remote service declares all of the properties to be optional,
most of the methods are marked as Nullable. Methods returning collection-based values however will return
an empty collection in case no corresponding data was received.
The sole purpose of these DTO objects is to encapsulate the exact raw JSON data as received from the remote
service in order to facilitate API integration by working with simple Java POJO's instead of nested JSON nodes.
Although there will be no intense post-processing of the actual JSON values a type-casting may be applied to
some of them to improve the usability and relieve the API user of this task.
