Class RefreshableThreadObject<T extends Creatable<T>>

java.lang.Object

com.att.inno.env.util.RefreshableThreadObject<T>

Type Parameters:

T -

public class RefreshableThreadObject<T extends Creatable<T>>
extends Object

RefreshableThreadObject

This is a ThreadLocal like implementation, but it responds to the LifeCycle mechanism for configuration refreshes, and implements Creatable (for use in destroy, etc).

In addition to the Thread instance semantics, it compares when the object was created versus the last "refresh(env)" call when getting, for the thread, and if necessary to replace the created object, destroying the previous.

In most cases, it's better to use the new "Pool" mechanism, as it deals with gaining and returning resources on an as needed basis. This, however, remains in the cases where specific Objects need to be retained to specific Threads.

There is no way to do this kind of specialized behavior in ThreadLocal.
