Class com.oroinc.net.pop3.POP3

- public class POP3
- extends SocketClient
The POP3 class is not meant to be used by itself and is provided
only so that you may easily implement your own POP3 client if
you so desire. If you have no need to perform your own implementation,
you should use POP3Client.
Rather than list it separately for each method, we mention here that
every method communicating with the server and throwing an IOException
can also throw a
MalformedServerReplyException , which is a subclass
of IOException. A MalformedServerReplyException will be thrown when
the reply received from the server deviates enough from the protocol
specification that it cannot be interpreted in a useful manner despite
attempts to be as lenient as possible.

public void addProtocolCommandListener(ProtocolCommandListener listener)
- Adds a ProtocolCommandListener. Delegates this task to
_commandSupport_ .
- Parameters:
- listener - The ProtocolCommandListener to add.
removeProtocolCommandistener
public void removeProtocolCommandistener(ProtocolCommandListener listener)
- Removes a ProtocolCommandListener. Delegates this task to

setState
public void setState(int state)
- Sets POP3 client state. This must be one of the
_STATE
constants.
- Parameters:
- state - The new state.
getState
public int getState()
- Returns the current POP3 client state.
- Returns:
- The current POP3 client state.
getAdditionalReply
public void getAdditionalReply() throws IOException
- Retrieves the additional lines of a multi-line server reply.
disconnect
public void disconnect() throws IOException
- Disconnects the client from the server, and sets the state to
DISCONNECTED_STATE
. The reply text information
from the last issued command is voided to allow garbage collection
of the memory used to store that information.
- Throws: IOException
- If there is an error in disconnecting.
- Overrides:
- disconnect in class SocketClient
sendCommand
public int sendCommand(String command,
String args) throws IOException
- Sends a command an arguments to the server and returns the reply code.
- Parameters:
- command - The POP3 command to send.
- args - The command arguments.
- Returns:
- The server reply code (either POP3Reply.OK or POP3Reply.ERROR).
sendCommand
public int sendCommand(String command) throws IOException
- Sends a command with no arguments to the server and returns the
reply code.
- Parameters:
- command - The POP3 command to send.
- Returns:
- The server reply code (either POP3Reply.OK or POP3Reply.ERROR).
sendCommand
public int sendCommand(int command,
String args) throws IOException
- Sends a command an arguments to the server and returns the reply code.
- Parameters:
- command - The POP3 command to send
(one of the POP3Command constants).
- args - The command arguments.
- Returns:
- The server reply code (either POP3Reply.OK or POP3Reply.ERROR).
sendCommand
public int sendCommand(int command) throws IOException
- Sends a command with no arguments to the server and returns the
reply code.
- Parameters:
- command - The POP3 command to send
(one of the POP3Command constants).
- Returns:
- The server reply code (either POP3Reply.OK or POP3Reply.ERROR).
getReplyStrings
public String[] getReplyStrings()
- Returns an array of lines received as a reply to the last command
sent to the server. The lines have end of lines truncated. If
the reply is a single line, but its format ndicates it should be
a multiline reply, then you must call
getAdditionalReply() to
fetch the rest of the reply, and then call
getReplyStrings
again. You only have to worry about this if you are implementing
your own client using the sendCommand methods.
- Returns:
- The last server response.
getReplyString
public String getReplyString()
- Returns the reply to the last command sent to the server.
The value is a single string containing all the reply lines including
newlines. If the reply is a single line, but its format ndicates it
should be a multiline reply, then you must call
getAdditionalReply() to
fetch the rest of the reply, and then call
getReplyString
again. You only have to worry about this if you are implementing
your own client using the sendCommand methods.
- Returns:
- The last server response.
