Detailed Description

PacketListener that checks the packet against a filter before passing it along to the listening object.

Constructor & Destructor Documentation

FilteredPacketListener::FilteredPacketListener (  void   )  [protected]

create a FilteredPacketListener with a NULL filter - works the same as a normal PacketFilter except that you need to override handlePassedPacket() instead of handlePacket().

FilteredPacketListener::FilteredPacketListener (  const PacketFilter &  f  )  [protected]

create a FilteredPacketListener with a given filter

Member Function Documentation

void FilteredPacketListener::handlePacket (  TraceIterator &  newPkt  )  [virtual]

checks the packet against the filter and calls handlePassedPacket if it passes or if the filter is NULL Implements PacketListener.
