HttpObject

All Known Implementing Classes:

AbstractHttpData, ByteBufHttpData, DefaultHttpData
```
public interface HttpData
extends HttpObject
```
HTTP/2 data. Helpers in this class create HttpData objects that leave the stream open. To create an HttpData that closes the stream, directly instantiate DefaultHttpData.
Implementations should generally extend AbstractHttpData to interact with other HttpData implementations.

    the decoded String
  - toInputStream
```
default InputStream toInputStream()
```
    Returns a new InputStream that is sourced from this data.
    Note, if this HttpData is pooled (e.g., it is the result of a call to HttpResponse.aggregateWithPooledObjects(ByteBufAllocator)), then this InputStream will increase the reference count of the underlying buffer. Make sure to call InputStream.close(), usually using a try-with-resources invocation, to release this extra reference. And as usual, don't forget to call ReferenceCountUtil.release(Object) on this HttpData itself too.
  - toReader
```
default Reader toReader(Charset charset)
```
    Returns a new Reader that is sourced from this data and decoded using the specified Charset.
  - toReaderUtf8
```
default Reader toReaderUtf8()
```
    Returns a new Reader that is sourced from this data and decoded using StandardCharsets.UTF_8.

```
default Reader toReaderAscii()
```
    Returns a new Reader that is sourced from this data and decoded using StandardCharsets.US_ASCII.
