Class PoolableBroadcasterFactory

  org.atmosphere.cpr.DefaultBroadcasterFactory
      org.atmosphere.pool.PoolableBroadcasterFactory

All Implemented Interfaces:

BroadcasterFactory

public class PoolableBroadcasterFactory
extends DefaultBroadcasterFactory

This class uses a PoolableProvider to retrieve instance of Broadcaster. This class doesn't validate the id of the Broadcaster [Broadcaster.setID(String)] and can return a Broadcaster with was already created under that name. Set trackPooledBroadcaster(boolean) or ApplicationConfig.SUPPORT_TRACKED_BROADCASTER to true to track duplication but be aware it can significantly reduce performance. Use the DefaultBroadcasterFactory is recommended under that scenario.

By default, this factory doesn't keep trace of created Broadcasters hence a new pooled Broadcaster will always be returned unless trackPooledBroadcaster(boolean) or ApplicationConfig.SUPPORT_TRACKED_BROADCASTER is set to true.

This Factory has been designed for application.

This factory is usefull when an application needs a short-lived Broadcaster.

Description copied from interface: BroadcasterFactory

Add a Broadcaster to the list.

Specified by:

add in interface BroadcasterFactory

Overrides:

add in class DefaultBroadcasterFactory

Parameters:

b - a Broadcaster

Returns:

false if a with the same name Broadcaster was already stored

remove

Remove a Broadcaster from the list.

Specified by:

remove in interface BroadcasterFactory

Overrides:

remove in class DefaultBroadcasterFactory

Parameters:

b - a Broadcaster

id - the ID

Returns:

false if wasn't present, or Broadcaster

lookup

public <T extends Broadcaster> T lookup(Class<T> c,
                                        Object id,
                                        boolean createIfNull,
                                        boolean unique)

Overrides:

lookup in class DefaultBroadcasterFactory

removeAllAtmosphereResource

public void removeAllAtmosphereResource(AtmosphereResource r)

Description copied from interface: BroadcasterFactory

Remove all instances of AtmosphereResource from all registered Broadcasters.

Specified by:

removeAllAtmosphereResource in interface BroadcasterFactory

Overrides:

removeAllAtmosphereResource in class DefaultBroadcasterFactory

lookupAll

public Collection<Broadcaster> lookupAll()

Description copied from interface: BroadcasterFactory

Return an immutable Collection of Broadcaster this factory contains.

Specified by:

lookupAll in interface BroadcasterFactory

Overrides:

lookupAll in class DefaultBroadcasterFactory

createBroadcaster

public Broadcaster createBroadcaster()

trackPooledBroadcaster

public PoolableBroadcasterFactory trackPooledBroadcaster(boolean trackPooledBroadcaster)

Set to true to enable tracking of Broadcaster.getID() duplication. Enabling this feature will significantly reduce the performance of the PoolableProvider. Use the DefaultBroadcasterFactory if you need to track's duplication.

Parameters:

Returns:

trackPooledBroadcaster

public boolean trackPooledBroadcaster()

Return true is Broadcaster instance are tracked, e.g stored in a Collection for duplicate id.

Returns:

Broadcaster instance are tracked, e.g stored in a Collection for duplicate id.
