| /** Interface defining an arbitrary bijective mapping from R^2 to R^2.<p> |
| |
| This interface provides methods to define an arbitrary bijective |
| mapping from R^2 to R^2, i.e. from the two-dimensional space of |
| real numbers onto itself, as is representable by the |
| <type>double</type> floating point type. The mapping must be |
| bijective, i.e. map a pair of real numbers to exactly one other |
| pair of real numbers an vice versa, to facilitate a working |
| inverse. Bijectiveness also implies completeness, i.e. for every |
| pair of real numbers there must be another pair that is mapped |
| upon them.<p> |
