Method Detail

getBackEnd

public BackEnd getBackEnd(FrontEnd fe,
                          Properties p)
                   throws IMTPException

Create a BackEnd in the fixed network and return a stub to communicate with it

Specified by:

getBackEnd in interface FEConnectionManager

Parameters:

fe - The FrontEnd container that is requesting the connection setup.

p - Additional (implementation dependent) connection configuration properties.

Returns:

A stub of the remote BackEnd.

Throws:

IMTPException

shutdown

public void shutdown()

Make this HTTPFEDispatcher terminate. Note that when the BackEnd receives the termination notification (explicitly sent in case of a self-initiated shutdown or attached to the response to the EXIT command), it closes the input connection. The InputManager gets an exception and, since it has been killed, terminates.

Specified by:

shutdown in interface FEConnectionManager

dispatch

public byte[] dispatch(byte[] payload,
                       boolean flush,
                       int oldSessionId)
                throws ICPException

Dispatch a serialized command to the BackEnd and get back a serialized response. Mutual exclusion with itself to preserve dispatching order

Specified by:

dispatch in interface Dispatcher

Throws:

ICPException

getConnection

protected Connection getConnection(TransportAddress ta)

doTimeOut

public void doTimeOut(Timer t)

Specified by:

doTimeOut in interface TimerListener
