Detailed Description

Abstract base class for TSL3DDataLayer objects.

TSL3DDataLayer is an abstract class and so cannot be instantiated directly. Clients should instantiate one of its derived classes (e.g. TSL3DMapData Layer).

Data layers should be destroyed by calling the destroy method rather than deleting them.

Deprecated: Deprecated as of MapLink 11.1. Advised to use MapLink Earth SDK instead.

◆ get3DExtent()

TSL3DBoundingBox TSL3DDataLayer::get3DExtent ( ) const

Query method to return 3D Bounding Box of the data layers contents.

Returns 3D Bounding Box.

◆ query()

TSL3DMapQuery * TSL3DDataLayer::query	(	const TSL3DBoundingBox &	extent,
		TSL3DSelector *	selector,
		int	drawingSurfaceID = -1 ) const

Query for entities in extent based on a client-supplied search criteria.

This method requests the TSL3DDataLayer to return a TSL3DMapQuery object which allows the user to access the data tiles required for the display of the specified area. The TSL3DMapQuery for a TSL3DDataLayer is only valid for immediate use since the data tiles to which they refer may be removed from memory if the cache is flushed.

The client must specify the selection policy through a suitable TSL3DSelector-derived object. This may analyse both 2D and 3D entities.

Parameters

extent	The 3D bounding box in which to query. Any 2D or 3D entity whose bounding box intersects that specified will be passed to the selector object for further analysis.
selector	pointer to a TSL3DSelector-derived object which specifies the selection criteria.
drawingSurfaceID	ID of drawing surface to use when querying entity extents. This is required when multiple drawingSurfaces are in use and when non-default drawing surface ID's have been used. If the default is used then the extents of symbol and text objects may be defaulted to their origin point. This also has an effect on groups containing such entities.
