Enclosing class:

WeakInterningHashSet<E>

protected static class WeakInterningHashSet.Entry<E>
extends WeakReference<E>

A weak reference holder that caches the hash code of the referent and is chained in the WeakInterningHashSet.entries to handle collisions.

Field Details

hashCode

public final int hashCode

The cached hash code.

next

public WeakInterningHashSet.Entry<E> next

The next entry in the collision chain.

Constructor Details

Entry

public Entry(E object,
 int hashCode,
 ReferenceQueue<? super E> queue)

Creates an entry thats part of the set's WeakInterningHashSet.internalQueue or WeakInterningHashSet.externalQueue.

Method Details

getNextEntry

public final WeakInterningHashSet.Entry<E> getNextEntry()

Returns the next entry in the collision chain with the same hashCode.

clear

public void clear()

Specialized to call doClear(). Derived classes should generally override this method only to impose synchronization. All the cleaning up of the fields of the entry should be done in doClear().

Overrides:

clear in class Reference<E>

doClear

protected void doClear()

clear

public final void clear(WeakInterningHashSet<E> set)

removes this entry from the set and then calls doClear().

toString

public String toString()

Returns the string value of the referent.

Overrides:

toString in class Object
