def data=(data)
  data = HashWithIndifferentAccess.new(data)
  multi_parameter_attributes = [] 
  data.each do |k,v|
    k.include?("(") ? multi_parameter_attributes << [k,v] : send(k+"=",v)
  end
  assign_multiparameter_attributes(multi_parameter_attributes)
end

#data_before_type_cast ⇒ Object

Returns a hash before it was typecasted, is empty when we didn’t set any data through any virtual accessors yet.
