Method Summary

Modifier and Type	Method and Description
private static int	Returns: the connection ID length connectionIdLength(byte the connection ID length byte. length) Reads a connection ID length from the connection ID length byte.
public QuicPacketDecoder.IncomingQuicPacket	decode(ByteBuffer the buffer with the bytes to be decoded buffer, CodingContext the decoding context context) Decode the contents of the given `ByteBuffer` and, depending on the `PacketType`, return a `QuicPacket` with the corresponding type.
private static QuicConnectionId	decodeConnectionID(ByteBuffer buffer)
private static QuicPacket.HeadersType	Returns: the headers type encoded in the given byte. headersType(byte the first byte of a quic packet first) Reads the headers type from the given byte.
private static boolean	Returns: true if the first packet in the buffer is a version negotiation packet. isVersionNegotiation(ByteBuffer the buffer containing the packet. buffer, int the offset at which the packet starts. offset) Returns true if the first packet in the buffer is a version negotiation packet.
public ByteBuffer	Returns: the next packet. nextPacketSlice(ByteBuffer a buffer containing coalesced packets buffer, int the offset at which the next packet starts offset) Find the length of the next packet in the buffer, and return the next packet bytes as a slice of the original packet.
public static QuicPacketDecoder	Returns: a decoder for the given Quic version or `null` of(QuicVersion the Quic protocol version number quicVersion) Returns a decoder for the given Quic version.
public static QuicPacketDecoder	Returns: A `QuicPacketDecoder` instance to decode the packet starting at the given offset. of(ByteBuffer A buffer containing a Quic packet buffer, int The offset at which the packet starts offset) Returns a `QuicPacketDecoder` to decode the packet starting at the specified offset in the buffer.
private QuicPacket.PacketType	Returns: the packet type encoded in the given byte. packetType(byte the first byte of a quic packet headerByte) Reads the Quic V1 packet type from the given byte.
public static QuicPacket.HeadersType	Returns: the header's type of the packet contained in this byte buffer. NONE if the header's type cannot be determined. peekHeaderType(ByteBuffer the byte buffer containing a packet. buffer, int the offset at which the packet starts. offset) Peeks at the headers type in the given byte buffer.
public static ByteBuffer	Returns: token or null if packet is malformed peekInitialPacketToken(ByteBuffer the buffer containing an initial packet. buffer) Returns a bytebuffer containing the token from initial packet.
public static ByteBuffer	Returns: A ByteBuffer slice containing the connection id bytes, or null if the packet is malformed and the connection id could not be read. peekLongConnectionId(ByteBuffer the buffer containing a long headers packet. buffer) Peeks at the connection id in the long header packet bytes.
public static LongHeader	Returns: A LongHeader containing the packet header data, or null if the packet is malformed peekLongHeader(ByteBuffer the buffer containing a long header packet. buffer) Peeks at the header in the long header packet bytes.
public static LongHeader	Returns: A LongHeader containing the packet header data, or null if the packet is malformed peekLongHeader(ByteBuffer the buffer containing a long header packet. buffer, int the position of the start of the packet offset) Peeks at the header in the long header packet bytes.
private int	Returns: the position just after the first packet present in the buffer. peekPacketEnd(QuicPacket.PacketType the first packet type. Must be INITIAL, HANDSHAKE, or ZERORTT. type, ByteBuffer the byte buffer containing the packet buffer) Returns the position just after the first packet present in the buffer.
public int	Returns: the size of the first packet present in the buffer. peekPacketSize(ByteBuffer A byte buffer containing quic packets buffer) Peek at the size of the first packet present in the buffer.
public QuicPacket.PacketType	peekPacketType(ByteBuffer buffer)
public QuicPacket.PacketType	peekPacketType(ByteBuffer buffer, int offset)
public static ByteBuffer	Returns: A ByteBuffer slice containing the connection id bytes, or null if the packet is malformed and the connection id could not be read. peekShortConnectionId(ByteBuffer the buffer containing a short headers packet. buffer, int the connection id length. length) Peeks at the connection id in the short header packet bytes.
public static int	Returns: the version of the packet in the buffer, or 0. peekVersion(ByteBuffer the buffer containing the packet. buffer) Returns the version of the first packet in the buffer.
public static int	Returns: the version of the packet in the buffer, or 0. peekVersion(ByteBuffer the buffer containing the packet. buffer, int the offset at which the packet starts. offset) Returns the version of the first packet in the buffer.
public void	skipPacket(ByteBuffer A byte buffer containing quic packets buffer, int The offset at which the packet starts offset) Advance the bytebuffer position to the end of the packet
