Class SegmentInfos.FindSegmentsFile
public abstract static
class
SegmentInfos.FindSegmentsFile
extends Object
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.
public FindSegmentsFile(File directory)
protected abstract Object doBody(String segmentFileName)
Subclass must implement this. The assumption is an
IOException will be thrown if something goes wrong
during the processing that could have been caused by
a writer committing.
public Object run()
