Member Function Documentation

bool CompoundPacketFilter::match (  const StreamKey &  key  )  const [virtual]

Match a StreamKey representing a Trace against a packet filter. Used to determine if all packets in a Trace are guaranteed to match the filter. Implements PacketFilter.

bool CompoundPacketFilter::match (  const TraceIterator &  pkt  )  const [virtual]

Match a packet against a packet filter. Match is done against a TraceIterator (a custom iterator defined relative to a Trace) so that the filter has access to relative features (e.g. frame.time_delta) Implements PacketFilter.

PacketFilter * PacketFilter::parse (  const std::string &  filterString  )  [static, inherited]

parser to generate packet filters from a filter string Returns: pointer to a new PacketFilter (allocated using new; caller is responsible for deallocating when finished)
