commit 910941c712f20816c70e06e64add5e8530218c1c Author: Isis Lovecruft isis@torproject.org Date: Tue Jun 9 00:16:37 2015 +0000
Define IBridge interface for sufficiently "bridge-like" things.
* ADD bridgedb.bridges.IBridge interface specification. * CHANGE the following classes to declare that they implement the IBridge interface: - bridgedb.bridges.BridgeAddressBase - bridgedb.bridges.PluggableTransport - bridgedb.bridges.BridgeBase - bridgedb.bridges.BridgeBackwardsCompatibility - bridgedb.bridges.Bridge
