K
- The type of key stored by the entry.V
- The type of value stored by the entry.public static class Maps.WeakEntry<K,V>
An Maps.BaseEntry
implementation which holds its value with a WeakReference
.
Because the referent of a soft reference cannot be changed, the setValue(V)
method throws UnsupportedOperationException
if invoked.
