Class Http2Reader

java.lang.Object
org.miaixz.bus.http.metric.http.Http2Reader
All Implemented Interfaces:
Closeable, AutoCloseable
public class Http2Reader extends Object implements Closeable
Reads HTTP/2 transport frames. This implementation assumes we haven't sent a SETTINGS frame to the peer that increases the frame size. Therefore, we expect all frames to have a maximum length of Http2.INITIAL_MAX_FRAME_SIZE.
