Constructor Detail

OutletProtocol

public OutletProtocol(Object synchThreadStart,
                      Socket clientSock,
                      String NozzleID,
                      String ChannelID,
                      ChannelState State)

Instantiates a new outlet protocol. The instance is set as a daemon thread and is started

Parameters:

synchThreadStart - the object the client should wait on until the thread is started and a notify is emitted

clientSock - the socket the protocol should write and read synchronization info

NozzleID - the id of the nozzle this protocol is acting on behalf of

ChannelID - the id of the channel the nozzle is interested in

State - the state where to emit incoming events and register for outgoing events

Method Detail

public Boolean HasConnected()

Checks if the outlet is connected to the inlet channel

Returns:

whether or not the outlet is connected to the inlet channel

StillConnected

public Boolean StillConnected()

Checks if the outlet is still connected to the inlet channel

Returns:

whether or not the outlet is still connected to the inlet channel

update

public void update(Observable o,
                   Object arg)

Specified by:
