Member Function Documentation

void LocationCache::add	(	QString	mac,
		QGeoCoordinate	pos
	)

DEPRECATED: Add a signle AP to the cache.

Parameters:

	mac	the AP's mac address
	pos	the position of the AP

void LocationCache::addCache

(

QHash< QString, QGeoCoordinate >

newCache

)

[slot]

Slot called if WiGLE has downloaded and parsed the APs.

The cache is written to disk.

Parameters:

newCache

is a QHash with the new APs' information

(

QList< QString >

macs

)

Get the mean position of a list of APs.

Parameters:

macs

a list of AP MAC addresses

Returns:

the mean position, or 0.0,0.0 if no AP was is the cache

QGeoCoordinate LocationCache::getPos

(

QString

mac

)

Lookup an APs position in the Cache.

Parameters:

mac

is the APs MAC addres

Returns:

the APs position or 0.0,0.0 if it is not in the cache

void LocationCache::init

(

)

center

)

[slot]

Set the size of the cache region.

The region is 0.1 x 0.1 deg large and is center is given as paramter

Parameters:

center

is the Center of the region
