Class OptionUnpackingMap<K,V>

java.lang.Object
  com.atlassian.bamboo.util.OptionUnpackingMap<K,V>

All Implemented Interfaces:

ConcurrentMap<K,V>, Map<K,V>

@ExperimentalApi
public class OptionUnpackingMap<K,V>
extends Object
implements ConcurrentMap<K,V>

This class provides an adapter between a Map containing Option values and a map providing direct nullable values. It's meant to be used for Google nullable Caches, which do not have mutability. If you're planning on using it, make sure you UT the method you're using! It says experimental in the annotation below!
