繼承與contextlib.contextmanager

Question

提供類

class SomeClass: 
    @contextlib.contextmanager 
    def on_connection(self, target_terminal, source_terminal): 
     ... 
     yield 
     ... 

如何從它繼承？

Answer 1

這是可能的contextlib.contextmanager模式與with塊超上下文管理，使結合：

class SomeDerivedClass(SomeClass): 
    @contextlib.contextmanager 
    def on_connection(self, target_terminal, source_terminal): 
     with super().on_connection(target_terminal, source_terminal): 
      ... 
      yield 
      ...
