Detailed Description

This interface is implemented by network protocols which want provide netfilter hooks to customize their behavior.

For example, implementing a reactive routing protocol can be done using this interface.

Member Function Documentation

dropQueuedDatagram()

virtual void inet::INetfilter::dropQueuedDatagram ( const Packet *  daragram )

pure virtual

Requests the network layer to drop the datagram, because it's no longer needed.

This function may be used by a reactive routing protocol when it cancels the route discovery process.

Implemented in inet::Ipv6, inet::Ipv4, and inet::NextHopForwarding.

registerHook()

virtual void inet::INetfilter::registerHook ( int  priority, IHook *  hook  )

pure virtual

Adds the provided hook to the list of registered hooks that will be called by the network layer when it processes datagrams.

Implemented in inet::NetfilterBase, inet::Ipv4, inet::Ipv6, and inet::NextHopForwarding.

Referenced by inet::sctp::SctpNatHook::initialize(), inet::tcp::TcpLwip::initialize(), inet::Pim::initialize(), inet::tcp::Tcp::initialize(), inet::Udp::initialize(), and inet::sctp::Sctp::initialize().

reinjectQueuedDatagram()

virtual void inet::INetfilter::reinjectQueuedDatagram ( const Packet *  datagram )

pure virtual

Requests the network layer to restart the processing of the datagram.

This function may be used by a reactive routing protocol when it completes the route discovery process.

Implemented in inet::Ipv6, inet::Ipv4, and inet::NextHopForwarding.

unregisterHook()

virtual void inet::INetfilter::unregisterHook ( IHook *  hook )

pure virtual

Removes the provided hook from the list of registered hooks.

Implemented in inet::NetfilterBase, inet::Ipv4, inet::Ipv6, and inet::NextHopForwarding.

Referenced by inet::sctp::SctpNatHook::finish().
