All Implemented Interfaces:

Closeable, AutoCloseable
```
public class MockIndexOutputWrapper
extends org.apache.lucene.store.IndexOutput
```
Used by MockRAMDirectory to create an output stream that will throw an IOException on fake disk full, track max disk space actually used, and maybe throw random IOExceptions.
