[Twisted-Python] twisted.internet.protocol.Protocol.connected flag purpose

[Adi Roiban]

Hi,

Looking at the code in trunk [1] I can see that
t.internet.protocol.Protocol will update the 'connected' attribute
upon makeConnection but will not update it on connectionLost

Is this the intended design?
Is this design documented somewhere ?

I have check the narrative docs [2] and api-docs[3] but this attribute
is not documented.

What is the purpose of t.internet.protocol.Protocol.connected ?

Thanks!
