Detailed Description

An attribute of a packet; the available attributes depends on the type of the packet.

Some attributes are universal (e.g. "frame.time"), whereas others are specific to packets of a particular protocol or application (e.g. "ip.src"). Packet attribute names are drawn from Ethereal notation, though there are some notable differences (e.g. only those attributes which refer to a single attribute are supported, so some e.g. "ip.addr" are not).

Examples:

profile_streams_thesis.cc, and test_harness.cc.

Member Data Documentation

std::string PacketAttribute::domain [protected]

string indicating the domain of the attribute, e.g. "frame", "ip", "tcp", etc.

std::string PacketAttribute::identifier [protected]

string identifying the attribute itself; an empty string means that the attribute merely specifies that the domain applies; e.g. IPv4Packet should return a value of PacketAttributeValue::TRUE when queried for an attribute of domain "ip" and identifier ""
