Constructor Detail

MessageReceiver

public MessageReceiver(ClientControls clientControls,
                       ChatStreamTokenizer tokenizer,
                       java.net.Socket socket)

Constructor of the class MessageReceiver.

Parameters:

outputArea - TextArea where the received messages are put out.

reader - BufferedReader where the messages are received from.

socket - Socket connected to the server.

Method Detail

getTimeout

public int getTimeout()

return the Timeout

Returns:

time the time to which the timeout is set. After invoking getTimout() you have to wait for time time in seconds; you understand ??

run

public void run()

Overrides the method run() in Thread.

Overrides:

run in class java.lang.Thread

readCommand

private java.util.Vector readCommand(ChatStreamTokenizer tokenizer)
                              throws java.io.IOException

Fetch one command from the input.

Parameters:

tokenizer - ChatStreamTokenizer which reads the command.

Returns:

a Vector containing the command.

setDisconnect

public void setDisconnect()

Give the MessageReceiver the signal to stop receiving. You must call this method to ensure that the MessageReceiver stops taking chars from the InputStream.

getReplyWaiter

public Waiter getReplyWaiter(java.lang.String msg)

returns a waiter thread which will wait for the event specified in msg, see Waiter for details.

Parameters:

msg - the message to wait for (e.g. LeaveReply)

handleNormalRequests

public void handleNormalRequests(java.util.Vector tokenlist)

handles all Requests

Parameters:

tokenlist - is the Vector that is read by the tokenizer
