A model of AlgebraicStructureTraits reflects the algebraic structure of an associated type Type.
Depending on the concepts that Type fulfills, it contains various functors and descriptive tags. Moreover it gives access to the several possible algebraic operations within that structure.
A model of AlgebraicStructureTraits is supposed to provide:
|
| |
|
The associated type.
| |
|
| |
|
Tag indicating the algebraic structure of the associated type.
| |
|
| |
|
Tag indicating whether Type is exact. This is either CGAL::Tag_true or CGAL::Tag_false. An algebraic structure is considered exact, if all operations required by its concept are computed such that a comparison of two algebraic expressions is always correct. The exactness covers only those operations that are required by the algebraic structure concept. e.g. an exact Field may have a Sqrt functor that is not exact.
| |
|
| |
|
Tag indicating whether Type is numerical sensitive. This is either CGAL::Tag_true or CGAL::Tag_false. An algebraic structure is considered as numerically sensitive, if the performance of the type is sensitive to the condition number of an algorithm.
| |
In case a functor is not provided, it is set to CGAL::Null_functor.
