DtVpfPointFeatureTile::DtVpfPointFeatureTile	(	DtVpfDatabase *	db,
		const DtString &	themePath,
		int	tileID,
		DtVpfTable *	featureTable
	)

Constructor takes a database, theme, tileID and feature table to generate an point feature tile.

Exceptions:

DtInvalidInput

if it cannot open the tables that it needs

virtual DtVpfPointFeatureTile::~DtVpfPointFeatureTile

[virtual]

Destructor.

DtVpfPointFeatureTile::DtVpfPointFeatureTile

Member Function Documentation

virtual bool DtVpfPointFeatureTile::initTile

(

)

[virtual]

Initializes the tile by loading the proper files.

Returns:

a boolean to indicate the success or failure of the load

Implements DtVpfTile.

virtual bool DtVpfPointFeatureTile::loadFeatures

(

DtVectorNetwork *

vectorNetwork

)

[virtual]

Loads the features from the VPF database to the GDB vector network.

Implements DtVpfTile.

virtual bool DtVpfPointFeatureTile::featureInArea	(	double	x,
		double	y,
		double	xMin,
		double	yMin,
		double	xMax,
		double	yMax
	)		const [virtual]

determines if point is in rectangle or not.

should hide the base class function of same name to prevent it from being used. Points will always fail the base class function's test.
