Class ThreadLocal.ThreadLocalMap.Entry

java.lang.Object
  java.lang.ref.Reference
      java.lang.ref.WeakReference
          java.lang.ThreadLocal.ThreadLocalMap.Entry

Enclosing class:

ThreadLocal.ThreadLocalMap

private static class ThreadLocal.ThreadLocalMap.Entry

extends WeakReference

The entries in this hash map extend WeakReference, using its main ref field as the key (which is always a ThreadLocal object). Note that null keys (i.e. entry.get() == null) mean that the key is no longer referenced, so the entry can be expunged from table. Such entries are referred to as "stale entries" in the code that follows.
