C# Class Lucene.Net.Index.SegmentInfos.FindSegmentsFile

Utility class for executing code that needs to do something with the current segments file. This is necessary with lock-less commits because from the time you locate the current segments file name, until you actually open it, read its contents, or check modified time, etc., it could have been deleted due to a writer commit finishing.
