Method Detail

initialize

public Broadcaster initialize(String id,
                              URI uri,
                              AtmosphereConfig config)

Description copied from interface: Broadcaster

Configure a Broadcaster.

Specified by:

initialize in interface Broadcaster

Overrides:

initialize in class DefaultBroadcaster

config - an AtmosphereConfig

Returns:

a usable Broadcaster.

incomingBroadcast

public abstract void incomingBroadcast()

Implement this method to broadcast message received from an external source like JGroups, Redis, etc.

outgoingBroadcast

public abstract void outgoingBroadcast(Object message)

Implement this method to broadcast message to external source like JGroups, Redis, etc.

Parameters:

message - outgoing message

getBroadcastHandler

protected Runnable getBroadcastHandler()

Overrides:

getBroadcastHandler in class DefaultBroadcaster

reconfigure

protected void reconfigure()

invokeOnStateChange

protected void invokeOnStateChange(AtmosphereResource r,
                                   AtmosphereResourceEvent e)

Overrides:

invokeOnStateChange in class DefaultBroadcaster

broadcastReceivedMessage

protected void broadcastReceivedMessage(Object message)

broadcast

public Future<Object> broadcast(Object msg)

Description copied from interface: Broadcaster

Broadcast the Object to all suspended responses, eg. invoke AtmosphereHandler.onStateChange(org.atmosphere.cpr.AtmosphereResourceEvent).

Specified by:

broadcast in interface Broadcaster

Overrides:

broadcast in class DefaultBroadcaster

Parameters:

msg - the Object to be broadcasted

Returns:

a Future that can be used to synchronize using the Future.get()

b

protected Future<Object> b(Object msg)

broadcast

public Future<Object> broadcast(Object msg,
                                AtmosphereResource r)

Description copied from interface: Broadcaster

Broadcast the Object to all suspended responses, eg. invoke AtmosphereHandler.onStateChange(org.atmosphere.cpr.AtmosphereResourceEvent) with an instance of AtmosphereResource, representing a single suspended response.

Specified by:

broadcast in interface Broadcaster

Overrides:

broadcast in class DefaultBroadcaster

Parameters:

msg - the Object to be broadcasted

r - an AtmosphereResource

Returns:

a Future that can be used to synchronize using the Future.get()

broadcast

public Future<Object> broadcast(Object msg,
                                Set<AtmosphereResource> subset)

Description copied from interface: Broadcaster

Broadcast the Object to all suspended response, eg. invoke AtmosphereHandler.onStateChange(org.atmosphere.cpr.AtmosphereResourceEvent) with a Set of AtmosphereResource, representing a set of AtmosphereHandler.

Specified by:

broadcast in interface Broadcaster

Overrides:

broadcast in class DefaultBroadcaster

Parameters:

msg - the Object to be broadcasted

subset - a Set of AtmosphereResource

Returns:

a Future that can be used to synchronize using the Future.get()
