end

#merged_contract ⇒ Object

Override these to control how your validations and merge variables get integrated with Launch Control defaults. For example:

def merged_options(options)
  options.merge(to_json)
end

This allows you to wrap any custom merge vars into a to_json method for a cleaner interaction.
