Detailed Description

A basic class for handling geometries in TerraLib.

All geometric classes of TerraLib are derived from TeGeometry. This class keep track of a geometryId and of a bounding box for the geometry

Note:

The Geometry classes in TerraLib use the Composite and the Visitor patterns

TeBox TeGeomComposite, TeGeomSingle
