Detailed Description

Functor to create WIT data files from PCAP traces.

The created data files are designed to be loaded into databases using LOAD DATA INFILE SQL commands.

anonymous enum [protected]

Enumerator:

channels_max

Maximum number of Wi-Fi channels.

wit::importer::importer ( const std::string & prefix )

Contruct a wit::importer given a prefix to use for data files.

The created data files will have the name <prefix>_c<channel> (for raw frames) and <prefix>_c<channel>_MACIndex (for address to integer mappings).

const wpl::prism::header * wit::importer::handle_prism_header	(	const std::string &	time_string,
		const void *	p,
		size_t	caplen
	)			`[inline, protected]`

Parse a frame's Prism header and update data files accordingly.

Returns:: A pointer to the Prism header, or NULL if the header is truncated. In this case, the data files have been fully updated and processing may stop safely for this frame.

template<class T >

void wit::importer::operator() ( const wpl::pkt::packet< T > & d ) [inline]

Import a frame in the data files.

Parameters:

`[in]`	h	Pointer to the frame's PCAP header.
`[in]`	p	Pointer to the frame.
