All Implemented Interfaces:

LocationAware, Closeable, AutoCloseable
```
public class AsyncBlockCompressedInputStream
extends BlockCompressedInputStream
```
Asynchronous read-ahead implementation of BlockCompressedInputStream. Note that this implementation is not synchronized. If multiple threads access an instance concurrently, it must be synchronized externally.
