module Decidim
# This class generates a notification based on the given event, for the given
# resource/recipient couple. It is intended to be used by the
# `Decidim::NotificationGenerator` class, which schedules a job for each recipient
# of the event, so that we can easily control which jobs fail.
class NotificationGeneratorForRecipient
# Initializes the class.
#
# event - A String with the name of the event.
# event_class - The class that wraps the event, in order to decorate it.
# resource - an instance of a class implementing the `Decidim::Resource` concern.
# recipient - the ID of the User that will receive the notification.
# extra - a Hash with extra information to be included in the notification.
def initialize(event, event_class, resource, recipient_id, extra)
@event = event
@event_class = event_class
@resource = resource
@recipient_id = recipient_id
@extra = extra
end
# Generates the notification. Returns `nil` if the resource is not resource
# or if the resource or the user are not present.
#
# Returns a Decidim::Notification.
