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

Dispose

public void Dispose()

Disposes the protocol state and unregisters from events

run

public void run()

Specified by:

run in interface Runnable

Overrides:

run in class Thread

HasConnected

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:

update in interface Observer
