module Recurly
class Schema
# A mixin that allows a class to be treated like a recurly
# object. This gives the class the power to describe
# it's schema. It adds the *define_attribute* method
# and a *schema* reader.
module SchemaFactory
# Gets the schema for this class
# @return [Schema]
def schema
@schema ||= ::Recurly::Schema.new
end
protected
# Macro that allows this class to define it's schema and associated
# attribute getters and setters.
#
# @example
# class Account
# extend Schema::SchemaFactory
# define_attribute :code, String, {:read_only=>true}
# end
# account = Account.new(code: "mycode")
# account.schema
# #=> Recurly::Schema
# acount.code = "newcode" # this method protected since read_only = true
# account.code
# #=> "mycode"

# Define the reader

self.attributes[name]
end
# Define the writer
