org.picocontainer.gems.adapters

Class ThreadLocalComponentAdapter

java.lang.Object

org.picocontainer.defaults.DecoratingComponentAdapter

org.picocontainer.gems.adapters.ThreadLocalComponentAdapter

All Implemented Interfaces:

java.io.Serializable, org.picocontainer.ComponentAdapter, org.picocontainer.defaults.ComponentMonitorStrategy, org.picocontainer.defaults.LifecycleStrategy, org.picocontainer.LifecycleManager

public class ThreadLocalComponentAdapter
extends org.picocontainer.defaults.DecoratingComponentAdapter

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 ThreadLocalComponentAdapterFactory for details.

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