java.lang.Object
- java.io.InputStream
- - io.helidon.media.common.DataChunkInputStream

All Implemented Interfaces:

Closeable, AutoCloseable
```
public class DataChunkInputStream
extends InputStream
```
Provides a bridge between a reactive Flow.Publisher in Helidon and an InputStream in Jersey. It subscribes to a Helidon publisher of data chunks and makes the data available to Jersey using the blocking InputStream API. This implementation is documented here /docs-internal/datachunkinputstream.md.

    originalPublisher - The original publisher.
    
    validate - executing thread validation
