DefaultBroadcaster (atmosphere-runtime 2.1.0-RC1 API)

java.lang.Object
- org.atmosphere.cpr.DefaultBroadcaster

All Implemented Interfaces:

Broadcaster

Direct Known Subclasses:

AbstractBroadcasterProxy, ExcludeSessionBroadcaster, SimpleBroadcaster
```
public class DefaultBroadcaster
extends Object
implements Broadcaster
```
The default Broadcaster implementation.
Broadcast messages to suspended responses using the caller's Thread. This basic Broadcaster use an ExecutorService to broadcast messages, hence the broadcast operation is asynchronous. Make sure you block on broadcast(Object).get()} if you need synchronous operations.

    Specified by:
    
    delayBroadcast in interface Broadcaster
    
    Parameters:
    o - the Object to be broadcasted
    delay - Amount of time to delay
    t - the TimeUnit of the delay
    
    Returns:
    a Future that can be used to synchronize using the Future.get()

```
public Future<Object> scheduleFixedBroadcast(Object o,
                                    long period,
                                    TimeUnit t)
```
    Description copied from interface: Broadcaster
    
    Broadcast periodically. The Object will be broadcasted after every period specified time frame expires. If the TimeUnit is set to null, the Object will be broadcasted when the first Broadcaster.broadcast(java.lang.Object) is invoked.
    
    Specified by:
    
    scheduleFixedBroadcast in interface Broadcaster
    
    Parameters:
    o - the Object to be broadcasted
    period - Every so often broadcast.
    t - a TimeUnit of period.
    
    Returns:
    a Future that can be used to synchronize using the Future.get()
  - scheduleFixedBroadcast

public Future<Object> scheduleFixedBroadcast(Object o,
                                    long waitFor,
                                    long period,
                                    TimeUnit t)
```
    Description copied from interface: Broadcaster
    
    Broadcast periodically. The Object will be broadcasted after every period specified time frame expires. If the TimeUnit is set null, the Object will be broadcasted when the first Broadcaster.broadcast(java.lang.Object) is invoked.
    
    Specified by:
    
    scheduleFixedBroadcast in interface Broadcaster
    
    Parameters:
    o - the Object to be broadcasted
