Constructor & Destructor Documentation

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 ( const DtVpfPointFeatureTile &  input )

private

Copy constructor is private to prevent copying.

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.

DtVpfPointFeatureTile& DtVpfPointFeatureTile::operator= ( const DtVpfPointFeatureTile &  input )

private

Assignment operator is private to prevent copying.
