Constructor & Destructor Documentation

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

Constructor takes a database, theme, tileID and feature table to generate the base tile that the subclasses build on.

virtual DtVpfTile::~DtVpfTile ( )

virtual

Destructor.

DtVpfTile::DtVpfTile ( const DtVpfTile &  input )

private

Copy constructor is private to prevent copying.

Member Function Documentation

virtual DtString DtVpfTile::tilePath ( ) const

virtual

returns the relative path to this tile

virtual DtString DtVpfTile::themePath ( ) const

virtual

returns the absolute path to the them for this tile

virtual bool DtVpfTile::loadFeatures ( DtVectorNetwork *  vectorNetwork )

pure virtual

abstract function that subclasses implement to load the features into the GDB vector network

Implemented in DtVpfAreaFeatureTile, DtVpfPointFeatureTile, and DtVpfLineFeatureTile.

virtual bool DtVpfTile::initTile ( )

pure virtual

Initializes the tile by loading the proper files.

Returns

a boolean to indicate the success or failure of the load

Implemented in DtVpfAreaFeatureTile, DtVpfPointFeatureTile, and DtVpfLineFeatureTile.

virtual bool DtVpfTile::featureInTile ( int  featureNumber ) const

virtual

determines whether a given feature is within this tile or not

virtual bool DtVpfTile::featureInAoi ( double  xMin1, double  yMin1, double  xMax1, double  yMax1, double  xMin2, double  yMin2, double  xMax2, double  yMax2  ) const

virtual

determines whether two rectangles overlap or not.

virtual DtVpfDatabase* DtVpfTile::database ( )

virtual

returns a pointer to the database that owns this tile

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

private

Assignment operator is private to prevent copying.
