# Create a module, and put this somewhere your controllers can access.

# In this example, all required parameters must be provided during

#
# There are two classes here belonging to the same data transfer object
# They follow the first example, but are hierarcal. Meaning that the DTO called
# BirthdayCard has a sub-DTO called BirthdayCard::Template.
#
# It is possible to have more deeply nested hiearcies within
# BirthdayCard::Template depending on the use-case.
#
# Finally, if the DTO becomes overly-complex, i.e. say BirthdayCard had 3 layers
# of hiearchy, and more than one branch:

minghz

#
# Mutable DTOs applies in case scenarios where the entire DTO may not be fully
# created in one go. Maybe it needs to be passed around several services and
# gradually enriched before being consumed.
#
# For example, passing around our birthday card to many friends to leave
# messages before finally delivering it to our recipient.
