org.infinispan.eviction

Interface EvictionManager<K,V>

@ThreadSafe
public interface EvictionManager<K,V>

Central component that deals with eviction of cache entries.

Typically, EvictionManager.processEviction() is called periodically by the eviction thread (which can be configured using org.infinispan.config.FluentConfiguration.ExpirationConfig#wakeUpInterval(Long) and org.infinispan.config.GlobalConfiguration#setEvictionScheduledExecutorFactoryClass(String)).

If the eviction thread is disabled - by setting org.infinispan.config.FluentConfiguration.ExpirationConfig#wakeUpInterval(Long) to 0 - then this method could be called directly, perhaps by any other maintenance thread that runs periodically in the application.

Note that this method is a no-op if the eviction strategy configured is EvictionStrategy.NONE.
