Detailed Description

The DtTdbManager class is intended to be used as a single point of interface to a terrain database, and to provide an "administrative" interface to that terrain database.

The "administrative" interface includes all operations that affect the terrain database directly as opposed to those that model interactions with a terrain database. For instance, loading, post-processing, and saving a terrain database are all administrative operations. However, performing an intersection to determine altitude at a point and other properties specific to that area of the terrain in question is really modeling an interaction with the terrain.

DtTdbManager& DtTdbManager::operator= ( const DtTdbManager & rhs )

private

virtual bool DtTdbManager::load	(	const DtFilename &	filename,
		const DtList &	searchPaths,
		DtString *	errorString = `0`
	)

virtual

Loads a database by filename.

The searchPaths parameter is passed on to DtTerrainDbFactory::loadDatabase (searchPaths is a list of DtString*s, holding a list of locations in which to search for the given fileName on the file system)

virtual bool DtTdbManager::load	(	const DtFilename &	filename,
		const DtFilename &	path = `DtFilename::nullFilename()`,
		DtString *	errorString = `0`
	)

virtual

Specify a path not derived from mtpFile.

virtual bool DtTdbManager::load	(	DtTdbMetafile &	tdbMeta,
		const DtFilename &	path = `DtFilename::nullFilename()`,
		DtString *	errorString = `0`
	)

virtual

Loads a database by metafile.

virtual Coordinate_System* DtTdbManager::coordinateSystemFrom	(	const DtFilename &	,
		const DtFilename &	path = `DtFilename::nullFilename()`,
		DtString *	errorString = `0`
	)

virtual

virtual bool DtTdbManager::hasOptionalFlags	(	int	flags,
		const DtFilename &	,
		const DtFilename &	path = `DtFilename::nullFilename()`,
		DtString *	errorString = `0`
	)

virtual

virtual bool DtTdbManager::loadPapermaps	(	DtTdbMetafile &	tdbMeta,
		DtTerrainDatabase *	db,
		const DtFilename &	path = `DtFilename::nullFilename()`
	)

virtual

Loads the only the papermaps using the coordinate system of the terrain database given If no database is given, it interally creates a temporary, empty db and uses its coordinate system.

virtual bool DtTdbManager::save ( const DtFilename & filename )

virtual

Saves a database by filename.

virtual bool DtTdbManager::exportPoly ( const DtFilename & filename )

virtual

Exports database polygons to a shapefile.

virtual bool DtTdbManager::createDatabaseFromExtent	(	const DtExtent &	,
		Coordinate_System *	coordSys = `0`
	)

virtual

Creates a simple terrain database from the supplied extent.

The coordinate system used will be the flat earth coordinate system (unless another is supplied). Note that is a coordinate system is supplied, the terrain database will take control of it

virtual bool DtTdbManager::unload ( )

virtual

Unloads the current database without saving it.

Returns: A boolean indicating whether or not the terrain was unloaded successfully or not.

virtual bool DtTdbManager::processDatabase	(	DtTerrainDatabase &	terrainDatabase,
		const DtGdbProcessingMetafileRecord &	postProcessingRecord
	)		const

virtual

Processes the specified terrain database, as configured in the postProcessing record.

Usually used to perform operations such as eliminating duplicate vertices and surfaces, or altering the resolution of the spatial subdivision.

virtual void DtTdbManager::setTerrainFactory ( DtTerrainDbFactory * fac )

virtual

Get/Set the terrainDbFactory.

virtual DtTerrainDbFactory* DtTdbManager::terrainDbFactory ( )

virtual

virtual const DtTerrainDatabase* DtTdbManager::terrainDatabase ( ) const

virtual

Get/Set the terrain database.

virtual DtTerrainDatabase* DtTdbManager::terrainDatabase ( )

virtual

virtual void DtTdbManager::setTerrainDatabase ( DtTerrainDatabase * t )

virtual

virtual const DtPaperMapDatabase* DtTdbManager::paperMapDatabase ( ) const

virtual

Get/Set the paper map database.

virtual DtPaperMapDatabase* DtTdbManager::paperMapDatabase ( )

virtual

virtual void DtTdbManager::setPaperMapDatabase ( DtPaperMapDatabase * p )

virtual

static DtTdbManager* DtTdbManager::create ( DtTerrainDbFactory * )

static

Static creator.

virtual DtTerrainDatabase* DtTdbManager::createTerrainDatabase ( )

virtual

Returns a newly allocated terrain database. Override this method to return your special subclass of the terrain database.

void DtTdbManager::setCheckImageForValidityCallback	(	DtCheckImageForValidityCallbackFcn	,
		void *
	)

Sets callbacks that will be used to see if image can be loaded. Return true to load image and false to not.

DtCheckImageForValidityCallbackFcn DtTdbManager::checkImageForValidityCallback ( void *& userPtr ) const

virtual bool DtTdbManager::loadFor3DVisualization	(	const DtFilename &	filename,
		Coordinate_System *	targetCoordinateSystem = `0`,
		DtString *	errorString = `0`
	)

virtual

Loads a database by filename, specifically for visualization in a 3D viewer.

Incoming filename must either be a shape vector data file (.shp) or a gdb file. If targetCoordinateSystem is non-NULL, transforms resulting terrain database into that coordinate system.

Note: Does not delete the coordinate system provided. (Earlier versions sometimes did)

virtual bool DtTdbManager::loadFeatureDataIntoTerrain	(	const DtFilename &	featureDataFilename,
		DtTerrainDatabase &	terrainDb,
		bool	crop = `false`,
		bool	planarize = `true`
	)

virtual

virtual DtString DtTdbManager::loadedTerrainFilename ( ) const

virtual

virtual void DtTdbManager::setFullyLoad ( bool )

virtual

virtual bool DtTdbManager::fullyLoad ( ) const
