Detailed Description

This is an VPF tile that contains point features.

It is a subclass of the abstract tile class and is used to load area features from a tile to a GDB vector network.

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

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.
