public class GigaSpaceDirectory
extends Directory

GigaSpace Directory is a Lucene directory built on top of GigaSpaces.

The direcotry implementation uses FileEntry as the meta data of a file written to the Space. And one or more FileBucketEntry to hold the entry data. Note, the bucket size can eb controlled during index creation, but if connecting to an existing index, the bucket index must be the same.
