All Implemented Interfaces:

Serializable

public class ProtocolCommandSupport
extends Object
implements Serializable

ProtocolCommandSupport is a convenience class for managing a list of ProtocolCommandListeners and firing ProtocolCommandEvents. You can simply delegate ProtocolCommandEvent firing and listener registering/unregistering tasks to this class.

Constructor Summary

ProtocolCommandSupport(Object source)
Creates a ProtocolCommandSupport instance using the indicated source as the source of ProtocolCommandEvents.

Method Summary

void	addProtocolCommandListener(ProtocolCommandListener listener) Adds a ProtocolCommandListener.
void	fireCommandSent(String command, String message) Fires a ProtocolCommandEvent signalling the sending of a command to all registered listeners, invoking their protocolCommandSent() methods.
void	fireReplyReceived(int replyCode, String message) Fires a ProtocolCommandEvent signalling the reception of a command reply to all registered listeners, invoking their protocolReplyReceived() methods.
int	getListenerCount() Returns the number of ProtocolCommandListeners currently registered.

Constructor Detail

ProtocolCommandSupport

public ProtocolCommandSupport(Object source)

Creates a ProtocolCommandSupport instance using the indicated source as the source of ProtocolCommandEvents.

Parameters:

source - The source to use for all generated ProtocolCommandEvents.

Method Detail

fireCommandSent

public void fireCommandSent(String command,
                            String message)

Fires a ProtocolCommandEvent signalling the sending of a command to all registered listeners, invoking their protocolCommandSent() methods.

Parameters:

command - The string representation of the command type sent, not including the arguments (e.g., "STAT" or "GET").

message - The entire command string verbatim as sent to the server, including all arguments.

fireReplyReceived

public void fireReplyReceived(int replyCode,
                              String message)

Fires a ProtocolCommandEvent signalling the reception of a command reply to all registered listeners, invoking their protocolReplyReceived() methods.

Parameters:

replyCode - The integer code indicating the natureof the reply. This will be the protocol integer value for protocols that use integer reply codes, or the reply class constant corresponding to the reply for protocols like POP3 that use strings like OK rather than integer codes (i.e., POP3Repy.OK).

message - The entire reply as received from the server.

addProtocolCommandListener

public void addProtocolCommandListener(ProtocolCommandListener listener)

Adds a ProtocolCommandListener.

Parameters:

listener - The ProtocolCommandListener to add.

removeProtocolCommandListener

public void removeProtocolCommandListener(ProtocolCommandListener listener)

Removes a ProtocolCommandListener.

Parameters:

listener - The ProtocolCommandListener to remove.

getListenerCount

public int getListenerCount()

Returns the number of ProtocolCommandListeners currently registered.

Returns:

The number of ProtocolCommandListeners currently registered.
