Class UnsafeOneToOneIndex<K,V>

java.lang.Object
com.atlassian.bamboo.plan.cache.index.util.unsafe.UnsafeOneToOneIndex<K,V>
@Internal @NotThreadSafe public class UnsafeOneToOneIndex<K,V> extends Object
A class that allows to index any key <-> value, one-to-one relationship. The key characteristics of this class is that, unlike Map<K,V>, it doesn't require linear scan when removing by value. Both K and V must have hashCode() and equals() correctly defined. This class is _not_ thread safe.
