Examples of JEDirectory

org.apache.lucene.store.je.JEDirectory
Port of Andi Vajda's DbDirectory to to Java Edition of Berkeley Database A JEDirectory is a Berkeley DB JE based implementation of {@link org.apache.lucene.store.Directory Directory}. It uses two {@link com.sleepycat.je.Database Db} database handles, one for storing filerecords and another for storing file data blocks.
