Every method that should be exposed to the interfaces supported in a given Ladon installation must register itself through the ladonize decorator. zJakob Simon-Gaardeé)Úglobal_service_collection)Ú validate_type)Ú*cs‡‡fdd„}|S)a’ The entry-point for all Ladon service methods. You could call this the magic-decorator that does initiates all the parsing analysing and pre-storing of service method capabilities and requirements. The ladonize decorator takes exactly the same amount of arguments as the method it is decorating plus one mandatory keyword argument *rtype* that type-defines the return type of the method. Each argument given to the decorator type-defines the order- wise corresponding parameter of the method being decorated:: class SessionService(object): @ladonize(str,str,rtype=str) def login(self,username,password): ... ... return session_id There are a couple of optional keyword arguments to ladonize aswell: +-------------------------+------------------------------------------------------------------------------------+ | keyword arg | Description | +=========================+====================================================================================+ | encoding | Control the encoding to be used internally in the service method for raw strings. | +-------------------------+------------------------------------------------------------------------------------+ | allow_unsafe_conversion | True means that Ladon will try to convert arguments and return values if nessecary | +-------------------------+------------------------------------------------------------------------------------+ cs<‡‡fdd„‰tƒjˆfˆžˆŽ}|ˆ_|jˆ_|jˆ_ˆS)Nc s–ˆj}|dd…}xPtt|ƒƒD]@}t|j|||ƒs t|j|j|j||j|t ||ƒƒ‚q Wˆ||Ž}t|j |ƒs’t |j|j|j t |ƒƒ‚|S)ab The Ladon inner injection function is called from the dispatcher. It does run-time type checking against the types registered with the service method. If everything is OK the user method is called. The result of the userspace-method is then checked before it is passed back to the dispatcher. éN) Ú_ladon_method_infoÚrangeÚlenrZ _arg_typesZArgTypeMismatchZsinfoÚ _func_nameZ _arg_namesÚtypeZ_rtypeZReturnTypeMismatch)ÚargsÚkwZlmiZcallargsZargidxÚres)ÚfÚinjector©ú9G:\easytimepro\master/mysite/ladon\ladonizer\decorator.pyr2s    z-ladonize..decorator..injector)rZadd_service_methodrZ_docÚ__doc__r Z func_name)rZladon_method_info)Údef_argsÚdef_kw)rrrÚ decorator1s (zladonize..decoratorr)rrrr)rrrÚladonizes 1rN)rÚ __author__Z!mysite.ladon.ladonizer.collectionrZmysite.ladon.typesrZ!mysite.ladon.exceptions.ladonizerrrrrrÚs
