Class SegmentInfos.FindSegmentsFile
- SegmentInfos
public static abstract class 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.
