Constructor Detail

DoChatExecutor

public DoChatExecutor(ServerThreadBase thethreadbase,
                      java.lang.String chatternamex,
                      byte[] chaticon)

Construct a DoChatExecutor. This constructor does three steps: First, it initializes its own state, then it registers its chatter with the main server classe. The third step is the most advanced: It registers its ServerThreadBase instance with the server's chat message logger object so that the messages are actually sent through the network connection.

Parameters:

thethreadbase - The ServerThreadBase object for this incarnation of the executor.

chatternamex - The name of the chatter as sent by the client.

chaticon - The iconpath to the personal icon.

Method Detail

query

public ServerReply query(ServerRequest sq)

The query handling method.

Overrides:

query in class CommandExecutor

Parameters:

sq - The request that has to be handled.

Returns:

A reply object.

leavingActions

public void leavingActions()

Clean up method to be called on disposal of this DoChatExecutor from the server stack. This method is used for cleaning up internal resources in case of disposal of the executor (e.g. due to LEAVESTATE or QUIT command or simply due to the connection being closed). This incarnation removes the receiving ServerThreadBase from the chatmessagelogger's receivers list. Otherwise, it could not be garbage collected and the server would run out of resources in the long run.

Overrides:

leavingActions in class CommandExecutor
