Python/InterfaceはPythonで、JavaやC#におけるいわゆるinterfaceの機能を実現します．
使用例
class SearchEngine:
app_key=''
def search(self, q):
pass
class YahooSearch:
app_key=1
def __init__(self):
interface(YahooSearch, SearchEngine)
class GoogleSearch:
app_key=''
def __init__(self):
# do not check method arguments
interface(GoogleSearch, SearchEngine, check_method_args=False)
def search(self, q, start):
pass
g = GoogleSearch() #ok
y = YahooSearch() #ng
実行結果
AssertionError: Method __main__.YahooSearch.search(self, q) is required by __main__.SearchEngine Variable __main__.YahooSearch.app_key <type 'str'> is required by __main__.SearchEngine
