XMPPConnection (smack_clone 4.0.7 API)

java.lang.Object
- org.jivesoftware.smack.XMPPConnection

Direct Known Subclasses:

XMPPBOSHConnection, XMPPTCPConnection
```
public abstract class XMPPConnection
extends Object
```
The abstract XMPPConnection class provides an interface for connections to a XMPP server and implements shared methods which are used by the different types of connections (e.g. XMPPTCPConnection or XMPPBOSHConnection). To create a connection to a XMPP server a simple usage of this API might look like the following:
```
 // Create a connection to the igniterealtime.org XMPP server.
 XMPPConnection con = new XMPPTCPConnection("igniterealtime.org");
 // Connect to the server
 con.connect();
 // Most servers require you to login before performing other tasks.
 con.login("jsmith", "mypass");
 // Start a new conversation with John Doe and send him a message.
 Chat chat = ChatManager.getInstanceFor(con).createChat("jdoe@igniterealtime.org", new MessageListener() {
     public void processMessage(Chat chat, Message message) {
         // Print out any messages we get back to standard out.
         System.out.println("Received message: " + message);
     }
 });
 chat.sendMessage("Howdy!");
 // Disconnect from the server
 con.disconnect();
 
```
Connections can be reused between connections. This means that an Connection may be connected, disconnected and then connected again. Listeners of the Connection will be retained accross connections.
If a connected XMPPConnection gets disconnected abruptly and automatic reconnection is enabled ( ConnectionConfiguration.isReconnectionAllowed(), the default), then it will try to reconnect again. To stop the reconnection process, use disconnect(). Once stopped you can use connect() to manually connect to the server.

```
    Abstract method that concrete subclasses of XMPPConnection need to implement to perform their way of XMPP connection establishment. Implementations must guarantee that this method will block until the last features stanzas has been parsed and the features have been reported back to XMPPConnection (e.g. by calling @{link serverRequiresBinding() and such).
    Also implementations are required to perform an automatic login if the previous connection state was logged (authenticated).
    
    Throws:

  - login
```
public void login(String username,
         String password)
           throws XMPPException,
                  SmackException,
                  SaslException,
                  IOException
```
    Logs in to the server using the strongest authentication mode supported by the server, then sets presence to available. If the server supports SASL authentication then the user will be authenticated using SASL if not Non-SASL authentication will be tried. If more than five seconds (default timeout) elapses in each step of the authentication process without a response from the server, or if an error occurs, a XMPPException will be thrown.
    Before logging in (i.e. authenticate) to the server the connection must be connected. It is possible to log in without sending an initial available presence by using ConnectionConfiguration.setSendPresence(boolean). If this connection is not interested in loading its roster upon login then use ConnectionConfiguration.setRosterLoadedAtLogin(boolean). Finally, if you want to not pass a password and instead use a more advanced mechanism while using SASL then you may be interested in using ConnectionConfiguration.setCallbackHandler(javax.security.auth.callback.CallbackHandler). For more advanced login settings see ConnectionConfiguration.
    
    Parameters:
    username - the username.
    password - the password or null if using a CallbackHandler.
    
    Throws:
    
    XMPPException - if an error occurs on the XMPP protocol level.
    
    SmackException - if an error occurs somehwere else besides XMPP protocol level.

                                      IOException
```
    Logs in to the server anonymously. Very few servers are configured to support anonymous authentication, so it's fairly likely logging in anonymously will fail. If anonymous login does succeed, your XMPP address will likely be in the form "123ABC@server/789XYZ" or "server/123ABC" (where "123ABC" and "789XYZ" is a random value generated by the server).
    
    Throws:

  - disconnect
```
public void disconnect()
                throws SmackException.NotConnectedException
```
    Closes the connection by setting presence to unavailable then closing the connection to the XMPP server. The XMPPConnection can still be used for connecting to the server again.
    
    Throws:
    
    SmackException.NotConnectedException
  - disconnect
```
public void disconnect(Presence unavailablePresence)
                throws SmackException.NotConnectedException
```
    Closes the connection. A custom unavailable presence is sent to the server, followed by closing the stream. The XMPPConnection can still be used for connecting to the server again. A custom unavailable presence is useful for communicating offline presence information such as "On vacation". Typically, just the status text of the presence packet is set with online information, but most XMPP servers will deliver the full presence packet with whatever data is set.
    
    Parameters:
    unavailablePresence - the presence packet to send during shutdown.
    
    Throws:
    
    SmackException.NotConnectedException

    Parameters:
    packetFilter - the packet filter to use.
    
    Returns:
    a new packet collector.
  - removePacketCollector
```
protected void removePacketCollector(PacketCollector collector)
```
    Remove a packet collector of this connection.
    
    Parameters:
    collector - a packet collectors which was created for this connection.
  - getPacketCollectors

  - addPacketListener
```
public void addPacketListener(PacketListener packetListener,
                     PacketFilter packetFilter)
```
    Registers a packet listener with this connection. A packet listener will be invoked only when an incoming packet is received. A packet filter determines which packets will be delivered to the listener. If the same packet listener is added again with a different filter, only the new filter will be used.
    NOTE: If you want get a similar callback for outgoing packets, see addPacketInterceptor(PacketInterceptor, PacketFilter).
    
    Parameters:
    packetListener - the packet listener to notify of new received packets.
    packetFilter - the packet filter to use.
  - removePacketListener
```
public void removePacketListener(PacketListener packetListener)
```
    Removes a packet listener for received packets from this connection.
    
    Parameters:
    packetListener - the packet listener to remove.
  - getPacketListeners
```
protected Map<PacketListener,XMPPConnection.ListenerWrapper> getPacketListeners()
```
    Get a map of all packet listeners for received packets of this connection.
    
    Returns:
    a map of all packet listeners for received packets.
  - addPacketSendingListener
```
public void addPacketSendingListener(PacketListener packetListener,
                            PacketFilter packetFilter)
```
    Registers a packet listener with this connection. The listener will be notified of every packet that this connection sends. A packet filter determines which packets will be delivered to the listener. Note that the thread that writes packets will be used to invoke the listeners. Therefore, each packet listener should complete all operations quickly or use a different thread for processing.
    
    Parameters:
    packetListener - the packet listener to notify of sent packets.
    packetFilter - the packet filter to use.
  - removePacketSendingListener
```
public void removePacketSendingListener(PacketListener packetListener)

    Parameters:
    packetListener - the packet listener to remove.
  - getPacketSendingListeners
```
protected Map<PacketListener,XMPPConnection.ListenerWrapper> getPacketSendingListeners()
```
    Get a map of all packet listeners for sending packets of this connection.
    
    Returns:
    a map of all packet listeners for sent packets.
  - addPacketInterceptor
```
public void addPacketInterceptor(PacketInterceptor packetInterceptor,
                        PacketFilter packetFilter)
```
    Registers a packet interceptor with this connection. The interceptor will be invoked every time a packet is about to be sent by this connection. Interceptors may modify the packet to be sent. A packet filter determines which packets will be delivered to the interceptor.
    NOTE: For a similar functionality on incoming packets, see addPacketListener(PacketListener, PacketFilter).
    
    Parameters:
    packetInterceptor - the packet interceptor to notify of packets about to be sent.
