Method Detail

tryToAddConnection

public boolean tryToAddConnection(java.lang.String strgKey,
                                  ClientConnection clientConnection)

Method tries to add ClientConnection to hashtable and is threadsave

Parameters:

strgKey -

connection -

Returns:

true if clientConnection was added, else false

removeConnection

public void removeConnection(java.lang.String strgNick)
                      throws NoSuchMemberException

remove a ClientConnection from controlCollection

Parameters:

strgNick - the String specifying the sessionKey of the ClientConnection to remove

getControlConnection

public ClientConnection getControlConnection(java.lang.String sessionKey)
                                      throws NoSuchMemberException

Parameters:

sessionKey - speifying the sessionKey of the requested ClientConnection

Returns:

the connection that is specified by the sessionKey

sendControlMessage

public void sendControlMessage(java.lang.String control,
                               java.lang.String message1,
                               java.lang.String message2,
                               java.lang.String message3)

sends to every ClientConnection from controlCollection a message that is handled by the ControlProtocolHandler

Parameters:

control - is the {@java.lang.String} that identifys the command to do in the ControlProtocolHandler

message1 - is a {@java.lang.String} specifying part1 of message

message2 - is a {@java.lang.String} specifying part2 of message The method is threadsave, because otherwise the iterator will be used by several threads (gleichzeitig).
