- Method Detail
  - getGameName
```
java.lang.String getGameName()
```
    Returns the 'game name' for this server. This should match the 'game name' set on connecting clients or they will be turned away.
  - getVersion
```
int getVersion()
```
    Returns the game-specific version of this server used for detecting mismatched clients.
  - getServices
```
HostedServiceManager getServices()
```
    Returns the manager for hosted services. Hosted services extend the functionality of the server.
  - broadcast
```
void broadcast(Message message)
```
    Sends the specified message to all connected clients.
  - broadcast
```
void broadcast(Filter<? super HostedConnection> filter,
               Message message)
```
    Sends the specified message to all connected clients that match the filter. If no filter is specified then this is the same as calling broadcast(message) and the message will be delivered to all connections.
    Examples:
```
    // Broadcast to connections: conn1, conn2, and conn3
    server.broadcast( Filters.in( conn1, conn2, conn3 ), message );

    // Broadcast to all connections exception source
    server.broadcast( Filters.notEqualTo( source ), message );
  
```
  - broadcast
```
void broadcast(int channel,
               Filter<? super HostedConnection> filter,
               Message message)
```
    Sends the specified message over the specified alternate channel to all connected clients that match the filter. If no filter is specified then this is the same as calling broadcast(message) and the message will be delivered to all connections.
    Examples:
```
    // Broadcast to connections: conn1, conn2, and conn3
    server.broadcast( Filters.in( conn1, conn2, conn3 ), message );

    // Broadcast to all connections exception source
    server.broadcast( Filters.notEqualTo( source ), message );
  
```
  - start
```
void start()
```
    Start the server so that it will begin accepting new connections and processing messages.
  - addChannel
```
int addChannel(int port)
```
    Adds an alternate channel to the server, using the specified port. This is an entirely separate connection where messages are sent and received in parallel to the two primary default channels. All channels must be added before the connection is started. Returns the ID of the created channel for use when specifying the channel in send or broadcast calls. The ID is returned entirely out of convenience since the IDs are predictably incremented. The first channel is 0, second is 1, and so on.
  - isRunning
```
boolean isRunning()
```
    Returns true if the server has been started.
  - close
```
void close()
```
    Closes all client connections, stops and running processing threads, and closes the host connection.
  - getConnection
```
HostedConnection getConnection(int id)
```
    Retrieves a hosted connection by ID.
  - getConnections
```
java.util.Collection<HostedConnection> getConnections()
```
    Retrieves a read-only collection of all currently connected connections.
  - hasConnections
```
boolean hasConnections()
```
    Returns true if the server has active connections at the time of this call.
  - addConnectionListener
```
void addConnectionListener(ConnectionListener listener)
```
    Adds a listener that will be notified when new hosted connections arrive.
  - removeConnectionListener
```
void removeConnectionListener(ConnectionListener listener)
```
    Removes a previously registered connection listener.
  - addMessageListener
```
void addMessageListener(MessageListener<? super HostedConnection> listener)
```
    Adds a listener that will be notified when any message or object is received from one of the clients.
    Note about MessageListener multithreading: on the server, message events may be delivered by more than one thread depending on the server implementation used. Listener implementations should treat their shared data structures accordingly and set them up for multithreaded access. The only threading guarantee is that for a single HostedConnection, there will only ever be one thread at a time and the messages will always be delivered to that connection in the order that they were delivered. This is the only restriction placed upon server message dispatch pool implementations.
  - addMessageListener
```
void addMessageListener(MessageListener<? super HostedConnection> listener,
                        java.lang.Class... classes)
```
    Adds a listener that will be notified when messages of the specified types are received from one of the clients.
  - removeMessageListener
```
void removeMessageListener(MessageListener<? super HostedConnection> listener)
```
    Removes a previously registered wildcard listener. This does not remove this listener from any type-specific registrations.
  - removeMessageListener
```
void removeMessageListener(MessageListener<? super HostedConnection> listener,
                           java.lang.Class... classes)
```
    Removes a previously registered type-specific listener from the specified types.
