public final Enum QuicPacket.HeadersType

Class Inheritance

extends Enum<QuicPacket.HeadersType>

java.lang.Object
java.lang.Enum
jdk.internal.net.http.quic.packets.QuicPacket.HeadersType

The Headers Type of the packet. This is either SHORT or LONG, or NONE when it can't be determined, or when we know that the packet is a stateless reset packet. A stateless reset packet is indistinguishable from a short header packet, so we only know that a packet is a stateless reset if we built it. In that case, the packet may advertise its header's type as NONE.
