StatefulSessionBeanCache (WildFly: EJB Subsystem 29.0.1.Final API)

Type Parameters:

K - the bean identifier type

V - the bean instance type

All Superinterfaces:

AffinitySupport<K>, BeanStatistics, Restartable

All Known Implementing Classes:

DistributableStatefulSessionBeanCache, SimpleStatefulSessionBeanCache
```
public interface StatefulSessionBeanCache<K,V extends StatefulSessionBeanInstance<K>>
extends Restartable, BeanStatistics, AffinitySupport<K>
```
A stateful session bean cache. Any StatefulSessionBean retrieved from this cache *must* invoke either StatefulSessionBean.close(), StatefulSessionBean.remove(), or StatefulSessionBean.discard() when complete.

Modifier and Type	Method	Description
`K`	`createStatefulSessionBean()`	Creates and caches a stateful bean using a generated identifier.
`StatefulSessionBean<K,V>`	`findStatefulSessionBean(K id)`	Returns the stateful bean with the specified identifier, or null if no such bean exists.
`Supplier<K>`	`getIdentifierFactory()`	Returns the identifier factory of this cache.
`default boolean`	`isRemotable(Throwable throwable)`	Checks whether the supplied `Throwable` is remotable - meaning it can be safely sent to the client over the wire.
