Member Function Documentation

void dtn::streams::StreamConnection::handshake	(	const dtn::data::EID &	eid,
		const size_t	timeout = 10,
		const char	flags = 0
	)

Do a handshake with the other peer. This operation is needed to communicate.

Parameters:

eid	The local address of this node.
timeout	The desired timeout for this connection.

Here is the call graph for this function:

void dtn::streams::StreamConnection::keepalive

(

)

send a keepalive

Definition at line 54 of file StreamConnection.cpp.

void dtn::streams::StreamConnection::reject

(

)

This method rejects the currently transmitted bundle

void dtn::streams::StreamConnection::shutdown

(

ConnectionShutdownCases

csc = CONNECTION_SHUTDOWN_SIMPLE_SHUTDOWN

)

This method shutdown the whole connection handling process. To differ between the expected cases of disconnection a connection shutdown case is needed.

CONNECTION_SHUTDOWN_IDLE The connection was idle and should go down now.

CONNECTION_SHUTDOWN_ERROR A critical tcp error occured and the connection is closed.

CONNECTION_SHUTDOWN_SIMPLE_SHUTDOWN The connection is ok, but a shutdown is requested from anywhere.

CONNECTION_SHUTDOWN_NODE_TIMEOUT The node of this connection is gone. So shutdown this connection.

CONNECTION_SHUTDOWN_PEER_SHUTDOWN The peer has shutdown this connection by a shutdown message.

Parameters:

csc	The case of the requested shutdown.
