org.picocontainer.gems.adapters

Class ThreadLocalized<T>

java.lang.Object

org.picocontainer.behaviors.AbstractBehavior<T>

org.picocontainer.gems.adapters.ThreadLocalized<T>

All Implemented Interfaces:

Serializable, Behavior<T>, ComponentAdapter<T>, ComponentLifecycle<T>, ComponentMonitorStrategy, LifecycleStrategy

public final class ThreadLocalized<T>
extends AbstractBehavior<T>

A ComponentAdapter that realizes a ThreadLocal component instance.

The adapter creates proxy instances, that will create the necessary instances on-the-fly invoking the methods of the instance. Use this adapter, if you are instantiating your components in a single thread, but should be different when accessed from different threads. See ThreadLocalizing for details.

Note: Because this implementation uses a Proxy, you can only access the methods exposed by the implemented interfaces of your component.
