Class IndexRevision

A IRevision of a single index files which comprises the list of files that are part of the current Lucene.Net.Index.IndexCommit. To ensure the files are not deleted by Lucene.Net.Index.IndexWriter for as long as this revision stays alive (i.e. until Release(), the current commit point is snapshotted, using Lucene.Net.Index.SnapshotDeletionPolicy (this means that the given writer's IndexDeletionPolicy should return Lucene.Net.Index.SnapshotDeletionPolicy).

When this revision is Release()d, it releases the obtained snapshot as well as calls DeleteUnusedFiles() so that the snapshotted files are deleted (if they are no longer needed).
