public class ProtocolCommandEvent
extends java.util.EventObject

There exists a large class of IETF protocols that work by sending an ASCII text command and arguments to a server, and then receiving an ASCII text reply. For debugging and other purposes, it is extremely useful to log or keep track of the contents of the protocol messages. The ProtocolCommandEvent class coupled with the ProtocolCommandListener interface facilitate this process.

ProtocolCommandEvent

public ProtocolCommandEvent(java.lang.Object source,
                    java.lang.String command,
                    java.lang.String message)

Creates a ProtocolCommandEvent signalling a command was sent to the server. ProtocolCommandEvents created with this constructor should only be sent after a command has been sent, but before the reply has been received.

参数:

source - The source of the event.

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.

ProtocolCommandEvent

public ProtocolCommandEvent(java.lang.Object source,
                    int replyCode,
                    java.lang.String message)

Creates a ProtocolCommandEvent signalling a reply to a command was received. ProtocolCommandEvents created with this constructor should only be sent after a complete command reply has been received fromt a server.

参数:

source - The source of the event.

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.

方法详细资料

getCommand

public java.lang.String getCommand()

Returns the string representation of the command type sent (e.g., "STAT" or "GET"). If the ProtocolCommandEvent is a reply event, then null is returned.

返回:

The string representation of the command type sent, or null if this is a reply event.

getReplyCode

public int getReplyCode()

Returns the reply code of the received server reply. Undefined if this is not a reply event.

返回:

The reply code of the received server reply. Undefined if not a reply event.

isCommand

public boolean isCommand()

Returns true if the ProtocolCommandEvent was generated as a result of sending a command.

返回:

true If the ProtocolCommandEvent was generated as a result of sending a command. False otherwise.

isReply

public boolean isReply()

Returns true if the ProtocolCommandEvent was generated as a result of receiving a reply.

返回:

true If the ProtocolCommandEvent was generated as a result of receiving a reply. False otherwise.

getMessage

public java.lang.String getMessage()

Returns the entire message sent to or received from the server. Includes the line terminator.
