org.jboss.aerogear.unifiedpush.message.serviceHolder.ApnsServiceHolder

@ApplicationScoped
public class ApnsServiceHolder
extends AbstractServiceHolder<com.notnoop.apns.ApnsService>

This cache creates and holds queue of used ApnsService with upper-bound limit of 10 created instances per given push message and variant. This allows for 10 concurrent connections to the APNs push network. Cache allows to return freed up services to the queue or free a slot for creating new services up to the limit. This cache also listens for VariantCompletedEvent event and stops all instantiated ApnsServices and frees the cache.

Method Detail

getFreeServiceSlotQueue

public javax.jms.Queue getFreeServiceSlotQueue()

Description copied from class: AbstractServiceHolder

Returns the Queue used as a counter of free services. This queue is populated with number of messages corresponding to limit of how many services can be created for given push network. The message is borrowed from this queue when new service is created. The message is returned to this queue when service is destroyed. That ensures that there won't be created more service instances in entire cluster of servers than given limit.

Specified by:

getFreeServiceSlotQueue in class AbstractServiceHolder<com.notnoop.apns.ApnsService>

Returns:

the Queue used as a counter of free services.
