public class SFSEvent
extends BaseEvent

SFSEvent is the class representing most of the events dispatched by the SmartFoxServer 2X Java client API.

The SFSEvent parent class provides a public property called arguments which contains specific parameters depending on the event type.

Example
The following example shows a generic usage of a SFSEvent; please refer to the specific event types for the params object content:

 package sfsTest;
 
 import com.smartfoxserver.v2.exceptions.SFSException;
 import sfs2x.client.SmartFox;
 import sfs2x.client.core.BaseEvent;
 import sfs2x.client.core.IEventListener;
 import sfs2x.client.core.SFSEvent;
 
 import java.util.Map;
 
 public class MyTest 
 {
     private SmartFox sfs;
     
     public MyTest() 
     {
               // Create a SmartFox instance
               sfs = new SmartFox();
         
         // Add event handler for connection
         sfs.addEventListener(SFSEvent.CONNECTION, new IEventListener() 
         {
             public void dispatch(BaseEvent evt) throws SFSException {
                 
                 // Retrieve event parameters
                 Map params = evt.getArguments();
                 
                 if ((Boolean)params.get("success"))
                     System.out.println("Connection established");
                 else
                     System.out.println("Connection failed");
             }
         });
         
         // Connect to server
         sfs.connect("127.0.0.1", 9933);
     }
 }

CONNECTION_RETRY
```
public static final java.lang.String CONNECTION_RETRY
```
The SFSEvent.CONNECTION_RETRY constant defines the value of the type property of the event object for a connectionRetry event.
Dispatched when the connection between the client and the SmartFoxServer 2X instance is interrupted abruptly while the SmartFoxServer 2X HRC system is available in the Zone.

The HRC system allows a broken connection to be re-established transparently within a certain amount of time, without loosing any of the current application state. For example this allows any player to get back to a game without loosing the match because of a sloppy internet connection.

When this event is dispatched the API enters a "freeze" mode where no new requests can be sent until the reconnection is successfully performed. It is highly recommended to handle this event and freeze the application interface accordingly until the connectionResume event is fired, or the reconnection fails and the user is definitely disconnected and the connectionLost event is fired.

No parameters are available for this event object.
Example
The following example handles a temporary disconnection event and the following connection resume:
```
 private void someMethod() 
 {
     sfs.addEventListener(SFSEvent.CONNECTION_RETRY, new IEventListener() 
     {
         public void dispatch(BaseEvent evt) throws SFSException 
         {
             // Freeze the GUI and provide some feedback to the player
             ...
         }
     });
     
     sfs.addEventListener(SFSEvent.CONNECTION_RESUME, new IEventListener() 
     {
         public void dispatch(BaseEvent evt) throws SFSException 
         {
             // Unfreeze the GUI and let the player continue with the game
             ...
         }
     });
     
     sfs.addEventListener(SFSEvent.CONNECTION_LOST, new IEventListener() 
     {
         public void dispatch(BaseEvent evt) throws SFSException 
         {
             System.out.println("Ouch, connection was lost. Reason: " + (String)evt.getArguments().get("reason"));
         }
     });
 }
 
```

CONNECTION_RESUME, CONNECTION_LOST, Constant Field Values

CONNECTION_RESUME
```
public static final java.lang.String CONNECTION_RESUME
```
The SFSEvent.CONNECTION_RESUME constant defines the value of the type property of the event object for a connectionResume event.
Dispatched when the connection between the client and the SmartFoxServer 2X instance is re-established after a temporary disconnection, while the SmartFoxServer 2X HRC system is available in the Zone.

The HRC system allows a broken connection to be re-established transparently within a certain amount of time, without loosing any of the current application state. For example this allows any player to get back to a game without loosing the match because of a sloppy internet connection.

When this event is dispatched the application interface should be reverted to the state it had before the diconnection. In case the reconnection attempt fails, the connectionLost event is fired.

No parameters are available for this event object.
Example
See the example provided in the CONNECTION_RETRY constant description.

See Also:

CONNECTION_RETRY, CONNECTION_LOST, Constant Field Values

This event is fired in response to a call to the loadConfig() method, but only if the connectOnSuccess argument of the loadConfig() method is set to false; otherwise the connection is attempted and the related SFSEvent.CONNECTION event type is fired.

No parameters are available for this event object.

Example
The following example loads an external configuration file:

 private void someMethod() 
 {
     sfs.addEventListener(SFSEvent.CONFIG_LOAD_SUCCESS, new IEventListener() 
     {
         public void dispatch(BaseEvent evt) throws SFSException 
         {
             // Configuration loaded successfully, now connect
             sfs.connect();
         }
     });
     
     sfs.addEventListener(SFSEvent.CONFIG_LOAD_FAILURE, new IEventListener() 
     {
         public void dispatch(BaseEvent evt) throws SFSException 
         {
             System.out.println("Failed loading configuration file");
         }

In this case there is no default way to know who the message was originally sent to. As this information can be useful in scenarios where the sender is chatting privately with more than one user at the same time in separate windows or tabs (and we need to write his own message in the proper one), the data parameter can be used to store, for example, the id of the recipient user.

The properties of the arguments object contained in the event object have the following values:

                 System.out.println("User " + sender.getName() + " sent me this PM: " + evt.getArguments().get("message"));
         }
     });
     
     // Send a private message to Jack

             UserCharacter character = getUserCharacter(sender.getId());
             
             character.x = dataObj.getInt("x");
             character.y = dataObj.getInt("y");
             
         }
     });
     
     // Send my movement to all players
     ISFSObject dataObj = new SFSObject();
     dataObj.putInt("x", myCharacter.x);
     dataObj.putInt("y", myCharacter.y);
