#
# ActiveModelSerializers provides hooks during the life cycle of serialization and
# allow you to trigger logic. Available callbacks are:
#
# * <tt>around_render</tt>
#
module Callbacks
extend ActiveSupport::Concern
include ActiveSupport::Callbacks

define_callbacks :render
end
# These methods will be included into any ActiveModelSerializers object, adding
# callbacks for +render+.
module ClassMethods
# Defines a callback that will get called around the render method,
# whether it is as_json, to_json, or serializable_hash
#
# class ActiveModelSerializers::SerializableResource
# include ActiveModelSerializers::Callbacks
#
# around_render do |args, block|
# tag_logger do
# notify_render do
# block.call(args)
# end

# def as_json
# run_callbacks :render do
# adapter.as_json

# # Note: So that we can re-use the instrumenter for as_json, to_json, and
# # serializable_hash, we aren't using the usual format, which would be:
# # def render(args)
# # adapter.as_json
# # end
