| void CNode::CloseSocketDisconnect | ( | ) |
| Network CNode::ConnectedThroughNetwork | ( | ) | const |
Get network the peer connected through.
Returns Network::NET_ONION for inbound onion connections, and CNetAddr::GetNetClass() otherwise. The latter cannot be used directly because it doesn't detect the former, and it's not the responsibility of the CNetAddr class to know the actual network a peer is connected through.

| std::shared_ptr< Sock > m_sock CNode::GUARDED_BY | ( | m_sock_mutex | ) |
Socket used for communication with the node.
May not own a Sock object (after CloseSocketDisconnect() or during tests). shared_ptr (instead of unique_ptr) is used to avoid premature close of the underlying file descriptor by one thread while another thread is poll(2)-ing it for activity.

The availability score is calculated using an exponentially weighted average.
This has several interesting properties:
This is expected to be called at a fixed interval of AVALANCHE_STATISTICS_REFRESH_PERIOD.
