Class OptionUnpackingMap<K,V>

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

All Implemented Interfaces:

java.util.concurrent.ConcurrentMap<K,V>, java.util.Map<K,V>

public class OptionUnpackingMap<K,V>
extends java.lang.Object
implements java.util.concurrent.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!
