HttpInput.Interceptor (Jetty :: Server Core 9.4.47.v20220610 API)

All Known Implementing Classes:

GzipHttpInputInterceptor, HttpInput.ChainedInterceptor

Enclosing class:

HttpInput
```
public static interface HttpInput.Interceptor
```
An interceptor for HTTP Request input.
Unlike InputStream wrappers that can be applied by filters, an interceptor is entirely transparent and works with async IO APIs.

An Interceptor may consume data from the passed content and the interceptor will continue to be called for the same content until the interceptor returns null or an empty content. Thus even if the passed content is completely consumed the interceptor will be called with the same content until it can no longer produce more content.
