Constructor & Destructor Documentation

SimplePacketFilter::SimplePacketFilter const SimplePacketFilter toCopy  ) 

parses the given filter string to generate a filter

Member Function Documentation

bool SimplePacketFilter::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 SimplePacketFilter::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

pointer to a new PacketFilter (allocated using new; caller is responsible for deallocating when finished)
