Class Maps.SoftEntry<K,V>

java.lang.Object
  java.lang.ref.Reference<T>
      java.lang.ref.SoftReference<V>
          oracle.javatools.util.Maps.SoftEntry<K,V>

Type Parameters:

K - The type of key stored by the entry.

V - The type of value stored by the entry.

All Implemented Interfaces:

java.util.Map.Entry<K,V>, Maps.BaseEntry<K,V>

Enclosing class:

Maps

public static class Maps.SoftEntry<K,V>
extends java.lang.ref.SoftReference<V>
implements Maps.BaseEntry<K,V>

An Maps.BaseEntry implementation which holds its value with a SoftReference.

Because the referent of a soft reference cannot be changed, the setValue(V) method throws UnsupportedOperationException if invoked.
