Member Function Documentation

◆ receivePayload()

void nfd::face::EthernetTransport::receivePayload	(	const uint8_t *	payload,
		size_t	length,
		const ethernet::Address &	sender
	)

Processes the payload of an incoming frame.

Parameters

payload	Pointer to the first byte of data after the Ethernet header
length	Payload length
sender	Sender address

◆ doClose()

void nfd::face::EthernetTransport::doClose ( )

finalprotectedvirtual

performs Transport specific operations to close the transport

This is invoked once by close() after changing state to CLOSING. It will not be invoked by Transport class if the transport is already CLOSING or CLOSED.

When the cleanup procedure is complete, this method should change state to CLOSED. This transition can happen synchronously or asynchronously.

Implements nfd::face::Transport.
