Member Function Documentation

void ndn::TcpTransport::close ( )

overridevirtual

Close the connection.

Implements ndn::Transport.

Definition at line 111 of file tcp-transport.cpp.

void ndn::TcpTransport::connect	(	boost::asio::io_service &	ioService,
		const ReceiveCallback &	receiveCallback
	)

overridevirtual

asynchronously open the connection

Parameters

ioService	io_service to create socket on
receiveCallback	callback function when a TLV block is received; must not be empty

Exceptions

boost::system::system_error connection cannot be established

Reimplemented from ndn::Transport.

Definition at line 81 of file tcp-transport.cpp.

shared_ptr< TcpTransport > ndn::TcpTransport::create ( const std::string & uri )

static

Create transport with parameters defined in URI.

Exceptions

Transport::Error incorrect URI or unsupported protocol is specified

Definition at line 41 of file tcp-transport.cpp.

bool ndn::Transport::isConnected ( ) const

inlineinherited

Return values

true	connection has been established
false	connection is not yet established or has been closed

Definition at line 122 of file transport.hpp.

bool ndn::Transport::isReceiving ( ) const

inlineinherited

Return values

true	incoming packets are expected, receiveCallback will be invoked
false	incoming packets are not expected, receiveCallback will not be invoked

Definition at line 128 of file transport.hpp.

void ndn::TcpTransport::pause ( )

overridevirtual

pause the transport

Postcondition: receiveCallback will not be invoked

Note: This operation has no effect if transport has been paused, or when connection is being established.

Implements ndn::Transport.

Definition at line 120 of file tcp-transport.cpp.

void ndn::Transport::receive ( const Block & wire )

inlineprotectedinherited

invoke the receive callback

Definition at line 134 of file transport.hpp.

void ndn::TcpTransport::resume ( )

overridevirtual

resume the transport

Postcondition: receiveCallback will be invoked

Note: This operation has no effect if transport is not paused, or when connection is being established.

Implements ndn::Transport.

Definition at line 129 of file tcp-transport.cpp.

void ndn::TcpTransport::send ( const Block & wire )

overridevirtual

send a TLV block through the transport

Implements ndn::Transport.

Definition at line 97 of file tcp-transport.cpp.

void ndn::TcpTransport::send	(	const Block &	header,
		const Block &	payload
	)

overridevirtual

send two memory blocks through the transport

Scatter/gather API is utilized to send two non-consecutive memory blocks together (as part of the same message in datagram-oriented transports).

Implements ndn::Transport.

Definition at line 104 of file tcp-transport.cpp.
