Class FileReadLockKey

java.lang.Object

org.infinispan.lucene.FileReadLockKey

All Implemented Interfaces:

Serializable, IndexScopedKey

public final class FileReadLockKey
extends Object
implements Serializable, IndexScopedKey

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.
