Enclosing class:

References

static final class References.WeakValueReference<V>
extends WeakReference<V>
implements References.InternalReference<V>

The value in a cache that holds values weakly. This class retains a reference to the key in the advent that the value is reclaimed so that the entry can be removed from the cache in constant time.

Method Details

getKeyReference

public Object getKeyReference()

Description copied from interface: References.InternalReference

Returns the key that is associated to the cache entry holding this reference. If the cache holds keys strongly, this is that key instance. Otherwise the cache holds keys weakly and the References.WeakKeyReference is returned.

Specified by:

getKeyReference in interface References.InternalReference<V>

Returns:

the key that is associated to the cached entry

setKeyReference

public void setKeyReference(Object keyReference)

equals

public boolean equals(Object object)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
