Package jdsl.geomobj.ref Description

This package contains implementations of the interfaces in jdsl.geomobj.api. For each interface two different implementations are provided, corresponding to different representations of the geometric objects: one uses integer arithmetic and the other uses exact rational arithmetic.
Ideally, geometric programs should never access directly the geometric information of the objects they manipulate, except for visualization purposes. All the geometric tests and constructions should be performed invoking the appropriate methods of jdsl.geomobj.api.GeomTester2D and jdsl.geomobj.api.GeomConstructor2D, implemented in GeomTester2DImpl and GeomConstructor2DImpl, respectively.
