Method Detail

connect

public void connect(java.lang.String servername,
                    java.lang.String sessionKey)
             throws ServiceRefusedException,
                    TimeoutException,
                    java.io.IOException

Connects to the given server with the given nickname.

Specified by:

connect in interface ReceiverClient

Parameters:

servername - The name of a spChatServer host, in a notation accepted by Socket.Socket(String,int).

sessionkey - The identification key for this session

Throws:

ServiceRefusedException - If the server rejected logging in. Generally not being able to open the socket produces some java.net exception.

TimeoutException - If the Server did not react within a certain timeout.

java.io.IOException - For problems in lower layers.

join

public void join(java.lang.String sessionKey,
                 java.lang.String channelName)
          throws ServiceRefusedException,
                 TimeoutException,
                 NotConnectedException,
                 java.io.IOException

join specified channel

Specified by:

join in interface ReceiverClient

Parameters:

sessionKey - that identifies the client

String - the Channel to join

leave

public void leave(java.lang.String channelName)
           throws ServiceRefusedException,
                  TimeoutException,
                  NotConnectedException,
                  java.io.IOException

leave the specified channel

Specified by:

leave in interface ReceiverClient

Parameters:

strChannel - the channel to left

disconnect

public void disconnect()
                throws java.io.IOException

Disconnect from the server. As a receiver is not really disconnected, this simply handles an internal state.

Specified by:

disconnect in interface ReceiverClient

Throws:

java.io.IOException - If something broken.

isConnected

public boolean isConnected()

Checks wether the client is connected. Currently, this checks only the internal state of the client, not wether the connection is operational.

Specified by:

isConnected in interface ReceiverClient

Returns:

true If the client (thinks it) is connected to a server.
