Class ThreadLocalStack<E>

java.lang.Object

org.jboss.as.jpa.container.ThreadLocalStack<E>

public class ThreadLocalStack<E>
extends Object

A thread local stack data structure. In order to avoid memory churn the underlying ArrayDeque is never freed. If we remove the deque when it is empty then this results in excessive deque allocations.
