Examples of org.springframework.util.ConcurrentReferenceHashMap

• org.springframework.util.ConcurrentReferenceHashMap
  A {@link ConcurrentHashMap} that uses {@link ReferenceType#SOFT soft} or{@linkplain ReferenceType#WEAK weak} references for both {@code keys} and {@code values}.

  This class can be used as an alternative to {@code Collections.synchronizedMap(new WeakHashMap>())} in order tosupport better performance when accessed concurrently. This implementation follows the same design constraints as {@link ConcurrentHashMap} with the exception that{@code null} values and {@code null} keys are supported.

  NOTE: The use of references means that there is no guarantee that items placed into the map will be subsequently available. The garbage collector may discard references at any time, so it may appear that an unknown thread is silently removing entries.

  If not explicitly specified this implementation will use {@linkplain SoftReference soft entry references}. @param < K> The key type @param < V> The value type @author Phillip Webb @since 3.2
