Method getLiveValue

output/java_guava/1.4.13/LocalCache.java:1960–1973

Gets the value from an entry. Returns null if the entry is invalid, partially-collected, loading, or expired. Unlike Segment#getLiveValue this method does not attempt to cleanup stale entries. As such it should only be called outside of a segment context, such as during iteration.

(ReferenceEntry<K, V> entry, long now)
