Detailed Description

Base class for all QUIC v1 packet forms that use the long header (Initial, 0-RTT, Handshake, Retry and Version Negotiation). Provides parsing shared by all of them: the QUIC version and the Destination/Source Connection IDs, which sit at a fixed offset (Destination) or immediately after it (Source) in every long-header packet

Member Function Documentation

◆ getDestinationConnectionId()

std::vector<uint8_t> pcpp::QuicV1LongHeaderLayer::getDestinationConnectionId ( ) const

Returns: The Destination Connection ID, or an empty vector if the packet doesn't contain enough data to read it

◆ getDestinationConnectionIdAsString()

std::string pcpp::QuicV1LongHeaderLayer::getDestinationConnectionIdAsString ( ) const

Returns: The Destination Connection ID as hex string, or an empty string if the packet doesn't contain enough data to read it

◆ getPacketType()

QuicPacketType pcpp::QuicV1LongHeaderLayer::getPacketType ( ) const

overridevirtual

Returns: The packet type, read from the Long Packet Type field of the long header

Implements pcpp::QuicV1Layer.

Reimplemented in pcpp::QuicV1VersionNegotiationLayer.

◆ getSourceConnectionId()

std::vector<uint8_t> pcpp::QuicV1LongHeaderLayer::getSourceConnectionId ( ) const

Returns: The Source Connection ID, or an empty vector if the packet doesn't contain enough data to read it

◆ getSourceConnectionIdAsString()

std::string pcpp::QuicV1LongHeaderLayer::getSourceConnectionIdAsString ( ) const

Returns: The Source Connection ID as hex string, or an empty string if the packet doesn't contain enough data to read it

◆ getVersion()

uint32_t pcpp::QuicV1LongHeaderLayer::getVersion ( ) const

Returns: The QUIC version
