Class RawDirectoryWrapper

java.lang.Object

org.apache.lucene.store.Directory

org.apache.lucene.store.FilterDirectory

org.apache.lucene.store.BaseDirectoryWrapper

org.apache.lucene.store.RawDirectoryWrapper

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public final class RawDirectoryWrapper
extends BaseDirectoryWrapper

Delegates all operations, even optional ones, to the wrapped directory.

This class is used if you want the most realistic testing, but still with a checkindex on close. If you want asserts and evil things, use MockDirectoryWrapper instead.
