Member Function Documentation

interpretCapabilityPacket()

virtual void dev::p2p::CapabilityFace::interpretCapabilityPacket ( std::weak_ptr< Session >  session, unsigned  packet_type, RLP const &  payload  )

pure virtual

Called by the Host when the messaege is received from the peer

Returns

true if the message was interpreted, false if the message had not supported type.

Implemented in taraxa::network::tarcap::TaraxaCapability.

messageCount()

virtual unsigned dev::p2p::CapabilityFace::messageCount ( ) const

pure virtual

Number of messages supported by the subprotocol version.

Implemented in taraxa::network::tarcap::TaraxaCapability.

name()

virtual std::string dev::p2p::CapabilityFace::name ( ) const

pure virtual

Subprotocol name, used in negotiating common capabilities with the peers.

Implemented in taraxa::network::tarcap::TaraxaCapability.

onConnect()

virtual void dev::p2p::CapabilityFace::onConnect ( std::weak_ptr< Session >  session, u256 const &  _peerCapabilityVersion  )

pure virtual

Called by the Host when new peer is connected. Guaranteed to be called first before any interpretCapabilityPacket for this peer.

onDisconnect()

virtual void dev::p2p::CapabilityFace::onDisconnect ( NodeID const &  _nodeID )

pure virtual

Called by the Host when the peer is disconnected. Guaranteed to be called last after any interpretCapabilityPacket for this peer.

Implemented in taraxa::network::tarcap::TaraxaCapability.

packetTypeToString()

virtual std::string dev::p2p::CapabilityFace::packetTypeToString ( unsigned  _packetType ) const

pure virtual

Convert supplied packet type to string - used for logging purposes.

Implemented in taraxa::network::tarcap::TaraxaCapability.

version()

virtual unsigned dev::p2p::CapabilityFace::version ( ) const

pure virtual

Subprotocol version, used in negotiating common capabilities with the peers.

Implemented in taraxa::network::tarcap::TaraxaCapability.
