Constructor Detail

ConnectionImpl

public ConnectionImpl(TorConfig config,
                      SSLSocket socket,
                      Router router,
                      TorInitializationTracker tracker,
                      boolean isDirectoryConnection)

Method Detail

getRouter

public Router getRouter()

Description copied from interface: Connection

Return the Router associated with this connection.

Specified by:

getRouter in interface Connection

Returns:

The entry router this connection represents.

isClosed

public boolean isClosed()

Description copied from interface: Connection

Return true if the socket for this connection has been closed. Otherwise, false.

Specified by:

isClosed in interface Connection

Returns:

true if this connection is closed or false otherwise.

bindCircuit

public int bindCircuit(Circuit circuit)

Description copied from interface: Connection

Choose an available circuit id value and bind this Circuit to that id value, returning the id value. Once bound, any incoming relay cells will be delivered to the Circuit with Circuit.deliverRelayCell(Cell) and other cells will be delivered with Circuit.deliverControlCell(Cell).

Specified by:

bindCircuit in interface Connection

Parameters:

circuit - The Circuit to bind to this connection.

Returns:

the circuit id value for this binding.

sendCell

public void sendCell(Cell cell)
              throws ConnectionIOException

Description copied from interface: Connection

Send a protocol Cell on this connection.

Specified by:

sendCell in interface Connection

Parameters:

cell - The Cell to transfer.

Throws:

ConnectionIOException - If the cell could not be send because the connection is not connected or if an error occured while sending the cell data.

removeCircuit

public void removeCircuit(Circuit circuit)

Description copied from interface: Connection

Remove a Circuit which has been bound to this Connection by a previous call to bindCircuit. After removing a Circuit, any further received incoming cells for the Circuit will be discarded.

Specified by:

removeCircuit in interface Connection

Parameters:

circuit - The Circuit to remove.

toString

public String toString()

Overrides:

toString in class Object

dashboardRender

public void dashboardRender(DashboardRenderer renderer,
                            PrintWriter writer,
                            int flags)
                     throws IOException

Specified by:

dashboardRender in interface DashboardRenderable

Throws:

IOException
