Examples of FileReadLockKey

org.infinispan.lucene.FileReadLockKey
Lucene's index segment files are chunked, for safe deletion of elements a read lock is implemented so that all chunks are deleted only after the usage counter is decremented to zero. FileReadLockKey is used as a key for the reference counters; a special purpose key was needed to make atomic operation possible. @author Sanne Grinovero @since 4.0
